Re: Reduced AF ares

Nothing whatsoever to do with the 1.6x crop. On most bodies the AF area is reduced with this lens (and also the 600/11). The only exception is the R3.

This is well documented online in many places, including by Canon.

OTOH if you choose to apply the 1.6x crop, you will get almost the whole screen area available for AF.

I knew that EF lenses had limitations on DSLRs as far as teleconverter and lens combo. But I didn't know that RF lenses and bodies had similar limitations.
