While there should be no issue for the 24L v1 & 2, and the 70-200 f/2.8L, L IS, L IS II, pages 79 onward of the 5d3 manual divide lenses into groups A to H.
In group A, all the AF points work, including all the dual cross-type AF points. The lenses above belong to group A.
In group B, all the AF points work, but only the central dual cross-type AF point works as such. This includes the 14L, 15mm f/2.8 fisheye, the 24-70 f/2.8L.
In group C, all the AF points work but none work as dual cross-type AF points (yoiu still have a healthy array of cross-type AF points). There is a whole slew of lenses here including the 100mm f/2.8 L and non-L macros, the 500mm, 600 mm, 17-40 f/4, and various telephotos with extenders.
In group D, some of the outer cross-type AF points become horizontal AF points only, and so on....Show more →
While I must confess I'm disappointed to see such a big effect of the lens used on the AF system I'm amused to see the 50/1.8 in group A while the 800/5.6 is in group F and the 1200/5.6 in group G.
Happy shooting,
Yakim.
