This is a follow-up to Why does Canon and Nikon limit or disable autofocus beyond certain f-numbers? I’m doing this to separate the AF aperture requirements from the linked question above. My goal here is to create a canonical answer for Canon AF aperture limits, with complete information for every Canon EOS model since the EOS D30.
What apertures are required for Canon EOS DSLR cameras to autofocus? What apertures are needed to enable cross-type and/or high-precision autofocus?
