For an hour and a half I chose a fast fix on the Nikon D5000. I chose from 50 1.8G AF-S and this. Fifty dollars focuses much faster, but 35 makes it almost silent. Abberations at 50, it seemed to me, is less. Otherwise, they are similar in drawing, if you do not take into account physics (f. distance, perspective on the frame). In my case, the choice in favor of 35mm is justified, because. In rooms with 50, there is nowhere to go to fit everyone. For the street would take 50-k. I noticed that the focus is now the front, then (less often) the back is obtained when shooting at close range with an open aperture. The rest gets the focus. With this lens, now I often take pictures in manual mode, the exposure meter is either in the dark, or vice versa. But the pictures are excellent)))
