To begin with, I remember how much an autofocus analogue costs for Nikon's full frame, the difference is colossal, we don't take 35mm 1.8g into account, because it's DX. But the price is not the only thing that pleasantly surprises. Good tenacious autofocus, fast, fairly quiet although not ultrasonic. After 2.8, sharpness is no worse than sigma artillery. In general, excellent glass, it looks pretty solid, the cost is super, now you can order a new one for 5500r from Ali.
