Glass for such a price is very good. I think that I will use it as a staff member, because lightweight and compact. And also the picture quality is noticeably better compared to the whale. I advise all owners of DX cameras. Don't forget to check carefully in the store! Pros: Aperture, dimensions, weight, price (about 8000), sharp, beautifully blurs the background (IMHO), assembly (despite the fact that China). Optimal fixed focal length (35 mm) for DX matrices. Got cons: In my copy, the front focus is slightly pronounced (within acceptable limits), a “barrel” is noticeable, small HA. Threaded hood and strives to fly off.
