Thought I'd share with anybody else interested in these lenses. These were taken with my Pentax K100D, the lens wide open, stabilization on, 1/45 shutter speed in my rather dimly lit room. All I can say is wow. In the full size third picture, the letters on the ibuprofen bottle are not only totally in focus but crisp, sharp, and clear. I can see a long and loving relationship growing with this lens, especially when I get a K1000. :hugs: For now, just keep a lookout in the general gallery for pictures I will be taking with this lens. I'm off to Loch Ness and the highlands tomorrow and am pretty sure there will be some wonderful pictures taken with this lens.
