The lens convinces with good sharpness at maximum aperture. However, I found the bokeh is not particularly appealing, the Schärfeverlauf is also the Sigma 50 better. Savings Nikon has unfortunately to the diaphragm blades from Aperture 2.2 can be seen in light spots corners, from 2.8 we have stop signs. The feel is adequate for the price, not as bad as the yogurt cups from Canon, but not as good as the Sigma 50 (no way).
However, price / performance ratio in the lens, it's a great introduction to photography with fixed focal lengths!
