Hi! Just a short notice. I have Sigma 28-135/3.8-5.6 zoom lens. Bought it off B&H for $170 about a year ago. Now it sells for even less. This is quite an average lens. It has only one advantage - versatility. The rest dissatisfies me. Especially the build quality - zoom creep was noticeable already after some 6 months of moderate use.
So, my general advise is to stay cautious if not away from Sigma budget optics... Hence, I would recommend Pentax. At least you get some 20 mm more on the long end... --- Boris Liberman www.geocities.com/dunno57 www.photosig.com/viewuser.php?id=38625
