Canon News has uncovered a patent for an APS-C 100-400mm F5.6-7.1 optical formula. (Richard also messed it up by not noticing it was APS-C at first)

The optical elements are fairly lightweight and the lens optics diameter would be somewhere around 52mm, which seems to fit with the EOS-M ecosystem. Or is this a sign of an RF APS-C camera coming out. The need for an APS-C 100-400 is puzzling if it’s for the RF mount though.

Canon appears to be going a different direction with their longer lenses for their mirrorless mounts than the other manufacturers. They seem to...
