Nikkor 50mm f2 (K type)

      I've only done some quick testing of my copy of this lens to be sure the Fotodiox Nikon to Eos adapter works properly, which it does.    I can tell you that the 50mm f2 is easy to focus without an af confirm chip, and it's really sharp at f2.  In fact, I couldn't see any difference between f2 and f4 in sharpness with my handheld shots.   Many photographers consider this lens a sleeper.  Upon first look I tend to agree.  I can't wait to test it in good light.  I also noticed it handles very well at close focus distances.   I think it will be a great macro lens with a bellows or tubes.   

     Update:  Bokeh fringe testing confirms this would be a very good macro lens.   This lens exhibits excellent control over bokeh fringing with little color shift.   The only noticeable artifact is a loss in contrast which is not a detriment to the photo.
