At my DX camera results with this lens for portraits quite a pleasant short telephoto focal length of 75mm, with which can work very well. Cropping is now total just become the bokeh might not quite so quiet / nice as the Nikkor 85mm 1.8 or 1.4G fail, but succeed anyway good and convincing. I am so happy in any case and above all - the people photographed are too.
It really succeed "pin sharp" photos in a very good, almost excellent image quality. It is also worth the amazingly high twilight performance of the lens - I have since then even in low-light situations (eg in the evening) almost ever use no flash. This lens also has a great value for money and gives me great pleasure again and again.
Unconditional purchase tip!
A practical tip for last: At my DX camera Nikon D5100 lens tends to overly "bright" images. The best photos with the most saturated colors arise in my experience with -0.7 to -1 EV.
