Good . apparently someone did not like what I said in the previous impression of this lens, the lens is excellent, in my case the dynamic distortions are ideal and even if you are looking for perspective in cases such as cities or streets I find that the sharpness works very well. ok its not great but this problem is easy to fix in the output that there is something that should never be allowed and moreover if its revain representing these sellers i believe are selling , can lose a certain tact in morality and confidence in the sale, the point is that it's not good for the camera "Sony Alpha a7II" if you do the approach, it's generally terrible, I will I won't explain anymore because I'm short on time, but if I can say that you have to go visit the Sony page and see the lenses compatible with this camera, which of course are very limited and very expensive in price is. Now if you have a NEX camera it works fine otherwise you would have to return the lens because it doesn't work well on "Sony Alpha a7II" and I think it won't go well with other Alpha a7- Models are working, hope you can understand and not spoil it. (That was almost 90% of what I said earlier and I'm talking about a good lens.) Here I leave a picture taken with the ILCE-A6000, it works perfectly in this camera.
