Some excellent, educational points in this thread. For the Zeiss dedicated lenses on the A7R, I find these lenses exhibit none of the faults noted in this thread. Non-dedicated lenses are a different issue. In my limited testing so far I have found the determining factor for a non-dedicated lens on the A7R is the lens design, not the WA, not the focal length, not the RF/SLR format, etc. I have the Contax G 28, 45, 90 lenses. The G28 is Biogon, and creates aberration (the magenta shift). The G45 is Planar, and is perfect. The G90 is Sonnar and...Show more →
I respectfully disagree with what is said here. I own a Minolta 50mm F1.4 that I would put up against any overpriced Zeiss or Leica lens. The Minolta lens I paid $35 from KEH. Both the Canon 55mm F1.2 and the Minolta I mentioned above easily out preform the Sony Zeiss 35mm, provided the lens are not pointed directly into the sun.
That said, I have found that results on the A7R vary with focal length. I recently purchased a Canon 200mm F2.8 that I am not happy with at all. My recent post of the dog was taken with that lens. And the Minolta 28mm W.Rokkor-x will not resolve perfectly at infinity, but has an up-side. The lens has wonderfully rich colors.
I have yet to find a wide-angle lens that I am truly happy with—I am open for suggestions, as long as the lens costs less than I paid for the camera. I was optimistic for my Canon 24mm F2.8, but sadly no…
I would not be happy at all if I zoomed in at 100% and my photographs looked like those posted by “adnan76” (please don’t take offense). If I can zoom in at 100%, and see out of focus blur, (unless it is in the very far corners), that is simple unacceptable. If I wanted out of focus and smeared color, I could simply use Sony E mount lenses.
