Amita, you may have gotten two bad copies in a row. Either that or (a) you have problems with your camera's autofocus, or (b) you are having trouble holding a telephoto lens steady (as I do).
As I posted here a while back, I tested the DA 50-200 systematically against the old SMC F 70-210 (a lens regarded as perhaps Pentax's best variable aperture telezoom). It was a systematic test, on a tripod, mud-brick wall, etc. The two lenses were very close. At Actual Pixels, the old F70-210 had just a bit more peripheral sharpness, but you would never notice it in ordinary usage. The DA 50-200 is a fine lens. Why not take the one you have and try it on a sturdy tripod. Joe -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
