An excellent staffer for crop, I think it will reveal itself to the fullest in FF. I bought it used with a hood and a UV filter, I can't get enough of it. I compare exclusively with tamron 17-50 2.8. The picture looks very expensive, the lens has its own pattern and I like it, it is sharp in the presence of lighting, you can also work in backlight, but carefully, but everyone seems to be like that. After buying the zoom, I immediately put it up for sale, I didn’t need a wide angle, the landscapes didn’t go in, and 35 mm on a fix is incomparably better, now I want to look at the photo, this is me for those who doubt, a fast zoom or a fix. I now have two running gears, a manual nikkor 105 and this is a miracle. Of course, there are more noble glasses f1.4, but the price.
