Zörk Panorama Shift Adapter
] is primarily offered with the idea to shoot for stitching. However, a first version of it was already launched during the mid 1980s. That way it is possible to achieve pictures with aspect ratios of up to 3:1 covering 120° of view with a 35mm lens - free of barrel distortion (equivalent to 17mm lenses in width). The adapter can be used in horizontal or vertical camera positions and is available with and without tripod socket. An additional L-bracket is available to maintain a static nodal point while shifting. The Zörk PSA can also be combined with their Multi Focus System to simulate a view camera (refer to System Cameras > Conversions > View Cameras
PSA is available with lens mounts for Mamiya 645, Pentacon 6, Pentax 645 and 67 and Hasselblad. The version for Pentax 645 can be used with adapters to mount lenses of the other systems. It can be ordered to directly mount to Canon EF (others available as well, incl. Nikon).
The shift range amounts to ±20mm with a full 360° of rotation.
Compatibility issues: The PSA is fully compatible in all versions with the pro grade SLRs and DSLRs. For EOS 10D, 20D, 30D etc. a work-around is necessary to achieve full rotation with the 645 models (contact Zörk for details*). For the consumer grade models with protruding flash housing above the bayonet the 645 models will not fit, using the 67 models is mandatory to retain full rotation there.
MSRPs: P645 and P6: 670$ each, Mamiya: 650$, HB and P67: 800$ each; add 130$ for integrated tripod socket and 100$ for L-bracket
Zörk is further reported
to offer a modified Tilt Adapter since 2011, I can't find it on their website though. It mounts Pentax 67 lenses (all down to 45mm focal length), features a 12-15° tilt range and is available for all 35mm mounts. The basic version goes for 280€, add 120€ for a tripod collar.
* "Prism overhang (usually part of a nonfunctional flash housing or nameplate) may be filed down to allow the PSA for 645 system lenses to rotate fully (note: Zörk does not authorize or officially support such modifications, but we will gladly explain to you what is required)." (source) Goes without saying: Will void warranty. Cutting holes into your DSLR might result in an unfavorable amount of dust entering the sensor area.
