The lens is measured by the price really good. The mentioned in many opinions, reflections, color aberration or distortion I can not or only minimally notice. I've done with my D80 in recent weeks many test shots, and even at full aperture, the sharpness is still completely ok course dimmed at 1-2 f-stops is a little more visible on sharpness, but these differences can be seen only at 100% and a good monitor , This fact is the way almost all lenses. What was interesting was the comparison with my Nikon 18-70. Only in some lighting situations such as backlit hard the prime lens is a little superior. Overall, however, the 35 mm is beautiful, natural colors, a great contrast and beautiful bokeh. But what's really important to me, at last you have again the opportunity (as before with my analogue SLR with 50mm) to customize depth of field and the additional stops less light are simply awesome. I can only advise everyone a "standard fixed focal length" to take to the range. In addition to framing the shot again much more aware. Four Star (not be worse must therefore) for the Plasik and the only normal fast autofocus.
