The 50mm 1.4 is well known for focusing issues such as back focusing. It isn't a good lens to test the accuracy of a camera's AF. Get a lens that has great performing AF like the 24-70 or 70-200.I mentioned I had both of those in addition to the 50mm
I'm after an idea on the expected consistency of the 7D Mark II with a 24-70 f2.8 (Mk I) and 70-200 IS f2.8 MkII in one shot outside on a target... Anyone tested theirs?
