depending on the lens well to slightly disappointing

Ansich not bad. Processing is fine. The autofocus problems I need not say more what, but I was aware in advance and therefore I focus on 95% manually. Everything works well with focus and peaking Zoom (50mm 1.8, EF-S 10-18)

- But I have to make concessions in terms of communication with the lenses.
My Tamron 70-300 VC USD interrupts the communication when changing the focal length (image is black). Only a switch to AF and back to MF bring the image back.
Perhaps a dee big exceptions and therefore bad luck.

- - My Canon 100mm 2.8 also has problems. When focusing, it may, depending on the distance happen that the aperture value increases. Of the possible 2.8 I then partially not able to come under 4.0 .. Beautiful exemption through open aperture is thus not really quite possible. That's my biggest gripe ..
