What can you expect from Zeiss? Sharpness is even at 1.4, Contrast is always and everywhere, the picture is gorgeous, there are a lot of details, but this miracle also weighs about 800 grams. You have to pay a lot for the quality of workmanship and materials . but it justifies it. With its pros. 1) The picture is simply gorgeous, sharpness, contrast even at the edges of the frame are magnificent 2) Metal, but for this money you should not expect another 3) Aperture adjustment ring on the lens itself (I shot it on old manual glasses and got used to it) 4) Works normally even at an open aperture Has some cons 1) Weight . it was hard to carry in the mountains 2) AF seemed thoughtful, but I have A7M2, maybe it will be better on R2 or M3 3) Bokeh (yes, I know, this is subjective, but still)
