Excellent sharpness and contrast. Slight vignetting at open aperture and edge blur, from 2.8 but both no longer an issue. Good Minimum focusing distance (25cm from the film plane). Bokeh in the vicinity Ok, when focusing on distant objects, it leaves much to be desired (donut-shaped highlights, restless Bokeh) - for a star minus. Good overall performance, handy, fun.
Nikon DSLR cameras without autofocus motor (D40, D60) of course contrary to the description NO autofocus. Rod autofocus on focus motor in Kamerageähäuse (D50, D80, D90 ...)
