|Canon Mount Adapter EF-EOS M (2012)|
In 2012 Canon finally launched its own mirrorless camera system with the EOS-M (refer to System Cameras > Mirrorless > Canon EOS M), which was based on the back then newly released EOS 650D. As had to be expected, the EOS M did not come with native EF mount. Instead, Canon supplied this optional adapter to mount EF and EF-S lenses to the EOS M. The adapter is compatible with all existing lenses (but according to the spec sheet (Canon Germany) not compatible with extenders) and comes with a removable tripod mount. Afterwards, there seem to be some further limitations in compatibility though. Canon published a huge list of lenses which will not focus properly or at least as fast as usual on the M3 and M10 [source].
Technical Specifications: 66.6mm x 28mm, 110g, no optical elements, feat. 8 electronic contacts
Viltrox Mount Adapter EF-EOS M (2013). The adapter is compatible with EF and EF-S lenses and offers AF and aperture functionality as well as a tripod mount.
Technical Specifications: 66.6mm x 26mm, 119g
Commlite Auto Focus Adapter EF-EOSM (2014). The adapter features an anti-shaking function (like the Viltrox Mount Adapter EF-NEX below) and a removeable 1/4" tripod mount. Compatible with EF and EF-S lenses.

|Canon Mount Adapter EF-EOS R (2018)|
The EOS R system is Canon's full-frame mirrorless camera system, which followed in 2018. There are 3 versions of the adapter:

This is just a selection of recent mirrorless cameras, that are expected to handle low light conditions nearly as easy as some DSLRs do since a few years (ISO ratings above 1000). They all meet or exceed a minimum of 4608 x 3456 pix sensor resolution (15.9 Mpix) and 125 - 16000 ISO range. Noticed the absense of MFT mount cameras? According to available DxO tests there is no MFT camera exceeding the ISO 1000 mark. The best one there is the Oly Pen EP-M2 with a rating of 932 (last check 2018.10). Samsung NX was great, but the whole series was discontinued after only 5 years in 2015, with a total of 18 bodies and a mere 15 lenses. Still much more lenses than Canon has to offer - and quite a good range as well.
For reference, the EOS 5D Mark II achieved a 23.7 bit, 11.9 EV, 1815 ISO rating, the 5D Mark III a 24.0 bit, 11.7 EV, 2293 ISO rating (refer to System Cameras > Cameras > Canon EOS DSLR for more models). Sure, both are (professional) fullframe sensor models and therefore have a huge advantage in lowlight, but that's what you usually will chose to do the shooting as best as possible technically. And seriously, when it comes to high ISO Canon is not even close to beat Sony and Nikon. So the above selection in fact does pretty well compared to Canon's consumer and prosumer APS-C models (70D ratings: 22.5 bit, 11.6 EV, 926 ISO ...), and as you can see, by above named standards for this list the EOS-M would have naturally been deleted for way too bad ISO performance, if this whole page wasn't basically about EOS :(. But hey ... there is always a little grain ready to enter the eye. With the release of the EOS M3 in 2015 Canon finally managed to exceed the ISO 1000 limit and to set itself at least ISO-wise ontop. Do not miss to read Victor Pavlovič's take on Sony NEX.
As an almost final note, it be mentioned, that a) for some reason I currently can't remember, DxO refuses to test Fujifilm cameras and b) as you'll see below, there as of today are no smart adapters available to mount EF lenses to Fuji X mount.
Some more random facts:
1) In the FinePix X-Pro1 Review you can look at a side-by-side sample shot comparison for noise levels of different cameras.
2) Meike offers underwater housings for the Sony NEX-3, NEX-C3, NEX-5 and NEX-5N. Nauticam offers housings for the Sony NEX-5N, NEX-6 and NEX-7.
Beastgrip Pro with Depth OF Field Adapter (2015) is a camera cage like adapter to mount SLR lenses to smartphones, so ... mirrorless - yes, camera - not really. The adapter can be fit to almost any mobile phone out there, with only a few exceptions (exceptions mentioned are the LG G Flex and LG G2). Early versions of the adapter required an upgrade set to be used with iPhone 7 or 7 Plus models, which changed during 2016 - the later versions do not need this set anymore.
Smartphone size requirements:
Lens position on the mobile phone (vertical):
All that yet doesn't help to mount your Canon EF lenses. But the Beastgrip Pro can be combined with the Beastgrip DOF Adapter, which will allow to mount any Canon EF mount lens directly (no further adapter required). The lens has to feature a manual focus ring, and the user guide mentions STM lenses to be incompatible (Do they mean EF-S? See below!). As the name already suggests, the DOF adapter produces an SLR-like depth of field. It consists of 3 modular rings, of which the middle one holds a focusing screen. It also ships with a 37-52mm step-up ring and a 37mm 10x close-up lens, which installs to the rear thread.
Mark I of the adapter was released in 2015, Mark II is about to follow in 10.2017. It features upgraded optics (including an achromatic macro lens) and a complete redesign (focus screen enclosure, rotating barrel with fixing clamps and more). The use of EF-S lenses with Mark II is not recommended, as they will cause extreme vignetting (the whole optical system is calculated for full frame lenses).
Yongnuo Digital YN43 Camera (2018). What the heck is that? It's a fully featured (mirrorless!) camera module with Canon EF mount (compatible with Canon EF-S as well). You can plug it infront of your mobile phone or use it independently, but you'll need your phone to configure camera settings and to see what you are doing (there is no LCD or viewfinder on the module). The app is available for Android and iOS. Here are the major specs:
Thanks to a tripod mounting thread on the bottom of the camera you could even mount it to a handgrip or something alike. Recharging is limited to USB connection by default, but this "FB-LP-E8" is just a Canon LP-E8 compatible battery (EOS 550D - EOS 700D), so you could as well buy the charger accordingly. Fun question: Does the Canon ACK-E8 fit as well?
|Basic Canon EF Lens to Sony NEX and MFT Electronic Mount Adapters|
Back in 2012 Kipon announced to develop electronic adapters to adapt Canon EF lenses to Sony NEX and MFT mirrorless cameras. At that time no further details were published other than that the adapters would support aperture control via camera body.
In the same year at Photokina Roxsen announced the arrival of a "Canon M adapter" as well ("coming soon"). Since Roxsen deals with Kipon, it's most likely been the same story.
Kipon finally came to release their EF-MFT AF and EF-S/E AF adapters during 2015. In 02.2016 a Kipon EF-S/E AF ND was announced for March, which would feature a slot for an included drop-in filter holder and 4x graduated neutral density filter. Baveyes Focal Reducers for EF-MFT and EF-S/E became available as well.
The abbreviations here are a bit misleading. The adapters are compatible with EF lenses: The EF in the model name seems to refer the Canon mount, and the S/E for Sony E, instead of 'Canon EF-S'/'E mount'.
Again Viltrox with their Mount Adapter EF-NEX (2013), Meike with their MK-S-AF4 (2013) and Commlite with the Auto Focus Adapter EF-NEX (the latter in white and black versions) indeed launched such adapters with electronic couplings quite soon. The adapters revived the AF and iris control, the Viltrox and Commlites even offered a built-in 'anti-shaking function'. All of them are equipped with a tripod mount as well - at least on the Commlites this mount is removeable.
Specifications: 66.6 x 26mm, 125g
Viltrox in the meanwhile released a 2nd version of their mount adapter - the EF-NEX II (2014), that fully fits the bigger image circle of Sony E mount full frame cameras (e.g. the A7, also available from Neewer) and a 3rd version - EF-NEX III (2016).
Specifications v2: 66.6 x 26mm, 143g
Specifications v3: 66.6 x 26mm, 141g, detachable tripod mount
Also on offer are - fully electronically coupled - a Viltrox Extension Tube EX-NEX (~2016), a macro extension tube mounting Canon EF lenses to Sony E-mount cameras up to full frame, and a Viltrox Mount Adapter EF-E (~2015), which also serves as a 3 stop speed booster and 0.71x focal length reducer and can be used with APS-C cameras.
Specifications EX-NEX: 74 x 32mm, 120g, detachable tripod mount
Specifications EF-E: 71 x 28mm, 176g, detachable tripod mount
In 2017 the Viltrox EF-M1 and EF-M2 Canon EF to MFT adapters were announced. Being compatible with both Canon EF and EF-S lenses, they will support electronic control of focus and iris and feature gold-plated electronic contacts and USB port for firmware updates. While the EF-M1 is a standard mount adapter, the EF-M2 adds 0.71x focal reducer and 1 stop speed booster functionality. As of May release dates and pricing were still t.b.a..
Specifications EF-M1: 67 x 25mm, 120g, tripod mount
Specifications EF-M2: 67 x 25mm, 135g, tripod mount
|Basic Canon EF Lens to Sony NEX, Fuji FX and MFT Dumb Mounts with Iris|
The already existing dumb mount versions (also available from Fotodiox, Pro-Optic or DSLRKit, just to name a few) comes with built-in adjustable, 14-bladed iris and uses an additional lens element. Even letting alone the additional lens element an iris behind the rear element of the EF mount lens isn't quite the same as an iris in its original position within the lens. Besides other side effects, using an aperture smaller than F6 will result in vignetting. The adapters are further not compatible with EF-S lenses. Despite not offering links to the Fuji FX mount here it does exist. Try a Google on "Kipon EOS-FX A".
|Basic Canon EF to Sony NEX, Fuji FX and MFT Dumb Mounts1|
Dumb is not just a word here. No electronic coupling, not even integrated iris like the Kipons above. Will work perfectly with the Samyangs, otherwise allow for no control beyond manual focus(1).
|Basic Canon EF to Sony NEX, Fuji FX and MFT Dumb Tilt Mounts1|
Now owning a Canon EOS and probably one of the Samyangs this one might give you one more argument to get a secondary mirrorless body instead of a C/EF T/S lens. These adapters will mount your C/EF lenses and provide an adjustable tilt range of up to 8° at a 360° rotation.
|Aputure DEC Canon EF to Sony NEX and MFT Wireless Remote Adapter (2015)|
The Aputure DEC mounts (2015) are primarily targeted at video applications. With the mounting ring comes a wireless controller grip which provides the physical interface to adjust iris and focus. The device further allows to save focus points, which works like Focus Preset known from Canon lenses. The grip can be used handheld or mounted to video head handles. The mount itself supports both EF and EF-S mount lenses. Both the grip and adapter feature OLED screens to display focal length, current aperture, radio signal and battery power. The system uses the 2.4GHz radio bandwidth and features a max. working range of 100m. Mount and control grip are powered by internal batteries lasting for 5 (mount) resp. 48 (grip) hours of operation. Both can be charged via Micro USB.
The Aputure DEC Vari-ND (2017) takes it a step further by adding a variable neutral density filter to the game. The filter can be adjusted (wirelessly of course as well as on the adapter itself) from ND8 to ND2048 (8 stops).
|Aputure DEC LensRegain Canon EF to MFT Wireless Remote Adapter (2016)|
The Aputure DEC LensRegain not only offers the wireless control of the first generation Remote Adapter, but also adds a 0.75x focus reducer.
|Cambo CA-GFX Canon EF to Fuji GFX Adapter (2017)|
In 2016 Fujifilm announced the development of an all new mirrorless medium format GFX camera series. The first model - the GFX 50S - was released in early 2017. Here are some core specifications (... and nooo, there is no 4K/8K movie mode ...):
As you can see the image circle of the Fuji GFX is much bigger than that of a usual Canon EOS camera, but as Hartblei and others already pointed out several times in the past, there are a few Canon EF mount lenses - especially the Canon TS-E models, that will still cover medium format. The resulting crop factor with the Fuji GFX will be 0.79x.
The Cambo CA-GFX is a dumb mount adapter with electronic control of the lens' iris build in. Aperture control is done via control dial on the adapter. The adapter further features a small display showing the selected aperture value as well as a Set/Preset button.
See DPReview's Studio Scene Comparison Tool for pixel peeping needs.
See System Cameras > Cameras > Hartblei Cam or ... Cameras > Alpa 12 for more medium format body options for Canon EF mount lenses. Kipon offers an Electronic Mount Adapter as well.
|Cambo CA-XCD Canon EF to Hasselblad X1D Adapter (2017)|
The Hasselblad X1D (2016) is another medium format mirrorless camera. Same thing as for the Fuji GFX above: Considering its MSRP and its feature set it's surely not the mirrorless camera you buy for your Canon glass. The adapter itself is pricey too and taken all these investments into account it's quite questionable as well, why someone already owning an X1D should want to buy the adapter to use Canon lenses on that camera, instead of just investing in original lenses. But there always are the exceptions from the rule. The core specs of the X1D are as follows:
The Cambo CA-XCD is a dumb mount adapter with electronic control of the lens' iris build in. Power is provided by an internal battery, which can be charged via USB. Aperture is controlled directly on the adapter.
Kipon offers an Electronic Mount Adapter as well.
|Fotodiox Pro EF-Sny(E) Fusion Smart AF Adapter and Fusion EF-E Mount (FE) ND Throttle Auto (2016)|
The Fotodiox Fusion adapters are smart adapters fully supporting electronic control of iris and focus of Canon EF and EF-S lenses mounted to Sony E and FE cameras (well, do not mount EF-S lenses to your FE cam though ...). The EF-Sny(E) is the basic version, the ND Throttle adapter adds a variable ND filter (ND2 - 400). Both come with removable tripod mount. As a little curiosity there are 2 different compatibility charts. According to the chart linked from the basic adapter's page they seem to work flawlessly with all tested original Canon lenses as well as Zeiss ZE lenses, but have problems dealing with most of Sigma's lenses (slow AF if working at all). See that compatibility chart here. The second chart is linked from the ND Throttle version's page (here) and clearly states, that only Canon lenses produced since 2006 are officially supported, but that a user also reported problems with 2 lenses within that range (Canon EF-S 15-85mm F3.5-5.6 IS USM and EF-S 55-250mm F4.0-5.6 IS), and it contains lenses that are not quite compatible according to the other chart's version. Good thing is the price though, especially the basic adapter is quite a bargain selling for 99$.
|Kipon Electronic Mount Adapters for Sony E (2014), MFT (2015), Fuji G and Hasselblad XCD (2017)|
Among all mount adapter manufacturers Kipon probably has the largest catalog of lens mount adapters available. For long they seemed to refuse to join the electronic mount business though. That changed in 2015. Since then the following adapters became available:
The EF-S/E AF and EF-NEX AF adapters were updated during 2015 to support Phase-Detection Autofocus (PDAF). There was no hint whether this was a firmware or hardware update.
In 2017 all 5 adapters were updated to version "II" (i.e. "Kipon EF-MFT AF II") with enhanced AF speed, stability and compatibility.
|Metabones EF - E Mount (2012) a.k.a. Conurus Canon EF Lens To Sony NEX Smart Adapter|
Conurus, who were already known for their conversions of Zeiss Contax N lenses to Canon EF mount using Sigma technology, together with Metabones, a company known for high quality adapters, developed an adapter to mount Canon EF lenses to Sony NEX cameras, which was released in 2012. The adapter was tested to work seamlessly with Sony NEX-3, NEX-5, NEX-5N, NEX-7, NEX-C3, NEX-FS100, FS700 and NEX-VG10 (other models are supposed to work as well, though not tested). It supported EF as well as EF-S mount (EF-S might result in some soft vignetting due to differing crop factors of EF-S (1.6x) and NEX (1.5x)). Support for electronic aperture control via camera as well as proper EXIF data from lens was given (aperture values are rounded up/down though, depending on the camera). IS functionality was tested with different lenses and should work with adapter firmwares v1.02 and newer (factory update required for older firmware versions and granted free shipping, but those were only shipped during the first few days after initial release). The IS was powered by the camera. The adapter featured a button to fully open the iris for manual focusing and bright frame preview as well as it offered a tripod screw mount. There was no AF support. E-M lenses worked flawlessly. Metabones published a list of lenses tested with the adapter. The mount was sold for an initial price of 400$.
In the second half of 2012 the adapter was updated to Version II, then featuring a detachable AS-style quick release plate, a round opening with anti-reflection surface and a power saving mode which reduces iris and image stabilization actuation during image preview. AF support was then given for Canon lenses majorly released since 2006* and seemingly a few third-party lenses** as well. The AF performance was not as fast as with Canon D-SLRs. According to Metabones it's slower than EOS M system or Sony NEX with their LA-EA2 adapter (for Sony A mount lenses), but claimed still faster than A mount lenses mounted using the Sony LA-EA1 adapter. For all other lenses the new version will just work like the old one. Version I Conurus adapters could be (factory) upgraded. For the FS100 and FS700 AF will work in Still Mode only, not in Movie Mode.
Conurus-Metabones Adapter v1 and v2 review/comparison at EOSHD.com.
In 2013 EF - E Mount Mark III was released by Metabones. Additionally to the above features Mark III supported the NEX VG900 (full frame cam) and seemless switching between EF and EF-S lenses (auto-crop). From this version on, Conurus was no longer mentioned nor did they post updates about the product on their site any longer. Still the mount - including the Speedbooster version - has its own subforum within the Conurus forum structuresm where I also found the following comment: "Conurus has an agreement with Metabones to supply the electronic technology exclusively to Metabones. So, unfortunately Conurus will not be able to sell the electronics to anybody else." (conurus 2013-04-24)
Mark IV followed in 2014. It features refined "internal structure" (coatings, electronics?). Otherwise the features list reads as/appearance looks like before.
Firmware v2.3 introduced support for Eye-AF, DMF and continuous iris control during video recording.
Mark V was introduced in early 2017 and came in two flavors - the T Smart Adapters and the T Cine Smart Adapters. The standard mount can be used for both stills and cine applications. It features newly added rubber seal at the camera mount to protect the camera from dust and moisture, an LED indicating current operation mode, IS status and lens-body-communication status and a switch to control the camera's built-in IS. The list of features meanwhile reads as follows:
As the name suggests, the T Cine Smart Adapter versions aim at cinematic applications. They add a Cinema Lock type EF mount to the list of features.
*These include the Canon EF-S 10-22mm F3.5-4.5 USM, EF-S 17-55mm F2.8 IS USM, EF-S 17-85mm F4.0-5.6 IS USM, EF-S 18-55mm F3.5-5.6, EF-S 18-55mm F3.5-5.6 IS, EF 22-55mm F4.0-5.6 USM (although much older), EF 28-90mm F4.0-5.6 III, EF 70-200mm F2.8L IS USM II, EF 70-200mm F4.0L IS USM, EF 70-300mm F4.0-5.6L IS USM, EF 70-300mm F4.0-5.6 IS USM, EF 85mm F1.2L II USM, EF 100-400mm F4.5-5.6L IS USM and EF 300mm F2.8L IS USM.
**Third-party lenses supported are Sigma 17-70mm F2.8-4.0 DC OS HSM (AF issues still reported at the long zoom end), Tamron 24-70mm F2.8 Di VC USD and Tokina 11-16mm F2.8 DX AT-X PRO.
|Metabones EF - E Speedbooster (2013+)|
In 2013 Metabones, in coop with Caldwell Photographic (design of the optics), released the Speed Booster in various flavors - including EF - E mount. Speed Booster "[...] increases the aperture by 1 stop (hence its name), increases MTF [resolution] and makes lens wider by a factor of 0.71x." Full electronic control as before, with limited (slow) AF support for Canon only lenses produced since 2006. The adapter comes with detachable Arca Swiss type tripod mount. Yet no full frame NEX support, no EF-S compatibility. The adapter received the TIPA Photo Accessory Award 2013.
In 2014 an EF - E Speedbooster Ultra edition was added. The Speedbooster Ultra features tantalum-based optical glass elements to furtherly improve corner sharpness and to reduce distortion and vignetting.
Warning: Do NOT use any mount adapters on it before deep-reading the manufacturer's footnotes (physical dangers as well as for electronic shortening).
By 2015 improved versions became available in form of the T Speed Boosters. They are technically identical to the older ones, but feature additional flocking of the interior to reduce internal reflections.
Firmware v2.3 introduced support for Eye-AF, DMF and continuous iris control during video recording.
The introduction of the 5th generation of Smart Adapters in 2017 went along with the release of the next generation of Ultra Speedboosters, which - right like the Smart Adapters - came in two versions: the Canon EF-E Mount T Speed Booster Ultra II and the Canon EF-E Mount T Cine Speed Booster Ultra. Refer to the EF-E Smart Adapters above for an updated list of features in detail. The Speedboosters are still produces with glass made by Caldwell Photographic. They increase the maximum aperture by 1 stop, increase MTF and increase the viewing angle by a factor of 0.71x.
Alternative: There is a number of so-called Focal Reducers or Lens Turbos available on the market, offering an increase of 1 stop, 0.72x crop and increase of MTF as well. But those are dumb mounts alltogether, and since they are offered by the usual suspects of comparable cheapness and contain optical elements, I wouldn't trust them without testing.
Metabones Speedbooster reviews are available at at diglloyd.com and EOSHD.com. Magnanimous Media posted a video on vimeo showing the effect using the EF - E Speedbooster.
|Metabones EF - M43 Mount (2014)|
This is the long awaited MFT version of the Metabones EF - E Mount, but with some limitations.
The adapter allows to electronically control the iris directly from the camera. Also it is powered by the camera, although it is possible to power the unit externally via Micro USB as well. Like it's NEX siblings, it comes with detachable tripod socket ready for Arca Swiss, Markins and Photo Clam. Image stabilization (IS), electronic manual focusing (E-M), EXIF data entries for focal length, aperture and zoom range are all supported. There is no list of compatible or incompatible lenses (although a list of tested-to-work, which contains a few Canons, a Sigma 18-200mm F3.5-6.3 and the Zeiss 35mm F2.0). Simply all Canon, Sigma, Tamron and Tokina lenses and the Conurus Contax N - EF mount conversions will work (may need registration with the adapter first though). As said above, there are some limitations compared to the EF - E mount. At this point AF or Dandelions (focus confirmation chips) as well as features like peripheral shading, color fringing and distortion correction are not supported. In contrary to the Speedbooster there is no word lost on EF-S, but the tested Sigma is a DX lens.
On to pricing. They will charge 400$.
|Metabones EF - M43 Speedbooster (2014)|
The Speedboster version of the EF - M43 Mount. Like the Speedbooster EF - E it increases the max. aperture by 1 stop, increases MTF and increases wide angle by a factor of 0.71x. The Speedbooster's feature and limitations list is otherwise identical to the EF - M43 Mount, except for adding incompatibility with Canon EF-S lenses, although it's possible to apply some modifications to the EF-S rear parts to make them fit. Third party DX lenses are compatible.
By 2015 there are two versions:
By 2015 also improved versions became available in form of the T Speed Boosters. They are technically identical to the older ones, but feature additional flocking of the interior to reduce internal reflections. Also the range of EF - MFT Speedboosters was accompanied by the Speed Booster XL 0.64x [MB_SPEF-M43-BT3], which increased the wide angle by a factor of 0.64x (still incompatible with Canon EF-S lenses) and the Speed Booster Ultra edition [MB_SPEF-M43-BT4] (see EF - E version for details).
For the Speedbooster optics add another 200$ to the cost of the basic mount version.
Magnanimous Media posted a video on vimeo showing the effect using the EF - M43 Speedbooster.
|Metabones EF - BM(P)CC Speedboosters (2014)|
Metabones offers dedicated MFT Speedbooster variants for the Blackmagic Cinema Camera (EF - BMCC) and for the Pocket Cinema Camera (EF - BMPCC). The BMCC version will also work with the Pocket Camera, but the BMPCC version will not fully cover the camera's sensor the other way around. Neither of them will fit any other MFT camera. The rest of its features and limitations are identical to the EF - M43 Speedbooster above.

|MTF Effect (2011) for Sony E and MFT|
MTF Effect in its initial form consists of the so called Control Unit, which is wire-coupled to an electronic mount for Canon EF lenses. The mounts feature support for IS and are available for MFT, Sony E (NEX and FS-100), AJA Cion and Sony FZ cameras. The only incompatible lens named (as of 2012) was the EF 1.2/85. There was no reason given, but it features E-M, which might be the reason. The control units come with illuminated display to show the current focal length and aperture (both in realtime, even during zoom with lenses not featuring constant aperture values). Aperture can be adjusted in 1/8th stop increments by turning a knob. Mark I of the control unit was powered by AA power cells lasting for a day of shooting. It will automatically shut down when idling to save energy.
In 2013 Control Unit Mark II was released. It was then powered by an external power source via D-Tap or 4-pin Hirose and size and weight were reduced. Mark III succeeded in 2015. This new version finally adds wireless control. The Mark III kit includes the control unit, the receiver, mounting bracket, charger for the control unit and a mount adaptor all packed in a Peli case.
About pricing ... they charge 650£ for the Control Unit and 350£ per mount. Alternately they also offer dumb mounts, which still go between 200£ and 275£. Mark III kits go for 1800£.

|Novoflex SL-EOS (2016) for Leica SL|
Haha, well. Nice try or wise consideration? After buying a Leica SL you might indeed be too broke for some time to afford genuine lenses for that camera as well. Most professional digital SLRs are still cheaper than an SL. So in that situation you can head for the Novoflex SL-EOS adapter, which allows to mount Canon EF lenses to the Leica SL. The adapter supports electronic control of aperture as well as autofocus, while image stabilization won't work.
At the time of the announcement there seems to be a limitation in compatibility - only about 30 Canon lenses are working, including zooms, fixed focal lengths and tilt-shifts. No further details are mentioned.
Pricing: The adapters are offered for 500€ and are on preorder. Release is reported for July 2016.
|PrimeCircle XE-EF Pro (2014) for Sony E and MFT|
LockCircle's entry into the hall of smart C/EF mounts starts with 5 variants (Arri, IMS, Sony FZ, Sony E and an MFT version). The basic system consists of the mount and a wired control unit [#XE-BM], which can be extended by another control unit [#XE-RM]. The clue: The control units communicate wirelessly with each other (but not with the mount directly) over distances of up to 150m. Means you do need the wired controller in the setup. The wired connection is limited by the choice of 4 cable lengths from 30cm to 12m. Aperture ramping is programmable. The control units are equipped with an LCD showing aperture, aperture ramping settings, focal length (min., current and max.) and focus check warning.
The mount has a size of 87 x 82 x 29mm, weights 360g and comes with a set of collimation shims.
The control units have a size of 98 x 63 x 43mm* and a weight of 280g. The units can be powered by an internal recharcheable (runs the units for 8 hours**) or an external 12V power source. The units feature a bunch of Lemo ports, one of which is a communication port for firmware updates and another one for external accessories, that might be released in the future. The units are both CE (868.3 MHz) and FCC (915 MHz) ready by a pressing of a button.
Pricing again is on the higher buget side - the whole system clearly adresses professional film production. The basic wired system goes for ~2600€, add another 400€ for the secondary wireless controller plus some for cables, cases etc.
* According to the brochure. The manual states 125 x 70 x 44mm.
** 6 hours according to the manual, 8 hours according to the brochure.
|Redrock Micro LiveLens MFT (2011)|
Hmm yah. Here we got another EF mount dedicated to MFT (digital still or video cameras alike). It allows to control the iris of most EF compatible lenses, including third party products, in increments of 1/3 or 1/2 stops. The unit weights 122g and is powered by an external 9V battery pack (adds another 85g and lasts for 20h of operation). The Redrock Micro LiveLens MFT is not compatible with the Redrock M2 Encore or M3 Cinema Lens Adapters ... refer to Still Lenses C/EF > Adapting EF > EF to Cine for their LiveLens Active Lens Mount.
"Additional lens features that require power may not be supported." (Redrock article page - description)
"Currently the LiveLens MFT [...] does not provide power for image stabilization." (Redrock article page - FAQ)
"LiveLens mft [sic!] does not power focus by wire lenses like the 85mm F1.2 and 300mm F2.8. It also does not work with Canon or third party teleconverters, extenders, or macro tubes." (Redrock article page - FAQ)
<rant>Alright, I admit it ... I never got the point why people would rave about Micro 4/3 when I just couldn't stand to wait for Canon to release a high ISO full frame DSLR any longer. Micro 4/3 actually seemed like a bad joke to me, because at the time of it getting established on the market, most people were already swearing about the near end of even APS-C sensor sized consumer DSLRs. Lots of especially spare time photographers wanted bigger sensors for higher ISO, less noise and less crop to finally use those wide angle lenses properly again, that were left in the shelf since the end of analog times, leave alone a minimum camera size required to come in handy and balanced with lenses. So why Micro 4/3? And hey ... here we go with just another bad joke ... and guess what? It's Micro 4/3 again, although not genuine. This is really pretty weak ... a 550$ adapter, that is - if at all - interesting for film makers, but doesn't support IS (nor AF) and I guess every change of aperture will cause numerous events of camera shake, since the touch pad to change the value is fixed to the adapter and you have to go through all the stop steps until the desired aperture is set. Communication of lens data to the body? Nope. And yeah, the Redrocks aren't even bothered to set up an exactly detailed product page. It's all achieved by magic. Reading the small print section you'll note, that you have to order the battery cable separately for another 50$ and that RrM doesn't mention the format of the required battery, that - wuh-huh - comes with the cable (might well be some proprietary format, that you have to order with the cable every 20 hours of use. Also not a single word about EF-S is lost. I'd guess it's not supported, but in fact is reported by users to work flawlessly. And what do we have there? Focus by wire lenses? Hmm. Welcome to the world of Canon EF! I guess the term these guys were looking for is Electronic-Manual. WTF.</rant>
Watching their fancy video tutorial, you'll finally learn, that the "cable" actually is a wired battery pack housing an exchangeable 9V 6LR61 standard battery block (available in 1.2A max.). And there even is an option to power the mount via so-called "D-tap power cable" (no clue what connector it has on the opposite side of the D-tab) connected to an IDX Endura 10s Li-Ion power pack (14.8V, 6.3A).
