Lenses: Limited Compatibility

Limited means, there is no or limited electronic transmission between lens and body resulting in loss of time priority and automatic modes (only if absolutely no coupling, see i.e. Zeiss for an exception), autofocus or E-TTL II support (as for now not available with cine lenses). Also In-Focus-Indicators will not show up (with exception of AF check feature/Dandelion explicitly being built-in).

* This is diagonal crop factor. Note the difference between diagonal and horizontal crop focussed under Camera Crop.

** Canon APS-C sensor sizes vary from 22.2 x 14.8mm to 22.7 x 15.1mm, while by watching the evolution of their sensors a size of 22.3 x 14.9mm has been used in all later models. Many other companies use sizes of 23.7 x 15.6mm (Ø28.4mm) instead, resulting in a crop factor of 1.5x.

*** Canon APS-H sensors also vary in size. The above size is valid for EOS 1D Mark I, II and IIN. Mark III featured a sensor sized 28.1 x 18.7mm, Mark IV a sensor sized 27.9 x 18.6mm and the old EOS D6000 even a sensor sized 27.6 x 18.4mm.

**** Digital full format derives from old 35mm film standard. Most of Canon's full frame cameras came with sensors sized on par with this specification, with the exception of EOS 1Ds Mark I (35.8 x 23.8mm) and EOS 5D Mark I (35.8 x 23.9mm).
