Note that we strongly recommend using a manual aperture lens (such as a Nikon lens) with a Canon body. With a digital lens, the aperture will close down to slightly different positions for each shot. This is not a problem for still photography, but for stop motion or time-lapse it creates "flicker". For Canon cameras, use a Nikon manual aperture lens with a Nikon to Canon lens adapter.
Stop Motion Firmware: If you have an EOS R/RP with Canon's special stop motion firmware, we recommend getting a Canon RF lens. You do not need to use a manual aperture lens in this case.
For Nikon cameras, use a Nikon manual aperture lens and put masking tape over the lens' electrical contacts.
A manual aperture lens has a physical ring for controlling aperture. Do not get a 'G' series lens, which has no aperture ring.
Here is a blog post from Adobe that describes the issue.
