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.

Thank you.

I figured it was documented somewhere.  It seems like the user's guide for the lens would be the sensible place.

I'm not complaining.  Just curious what it was.

So far, except for the lens being obviously very dark at f/11, the image quality is very good.
