AF may not work if the maximum aperture of the lens plus any EF Extender or other teleconverter attached is smaller than f/8.
Some Tamron lenses may have unsatisfactory AF accuracy.
No support for Focus Stacking and Focus Bracketing.
EF-mount lenses are not silent but may make audible click noises during autofocus operation and iris changes which may be picked up by the built-in microphone of the camera. An external microphone is recommended for video.
Use of Canon Cinema lenses such as CN-E 18-80mm T4.4 L IS KAS S for still photography is not supported.
Iris changes are in 1/8 stop steps which may be noticeable in video recordings. Programmed exposure mode and shutter priority exposure mode should not be used for video. This limitation does not apply to Cinema EOS lenses which permit fine resolution iris control, such as CN-E 18-80mm T4.4 L IS KAS S.
No support for in-camera correction such as peripheral shading, CA and distortion
