8 out of 10 points and recommended1:2 macro, zoom range, light, good handling, delivers very sharp images, best value for money!!CAÃÂ´s, but only in very contrasty situations, easy to remove in PS
I use this lens on a pentax k10dreviewed October 13th, 2008 (purchased for $120)
It is my first lens beside the 18-55 kit lens.
After reading much reviews i found out myself that this tamron lens is veery sharp and produces very nice crispy images. It is a little bit heavier as the lens kit, but nothing to worry about. The handling is nice, only when fully zoomed its kind of a third leg :)
I recommend this lens as a 2nd lens to anyone who has just the kit lens. You will be astonished how unsharp the 18-55 kit lens really is, so go and get it, you wont regret it :)
