55-200 Zooms: Sigma AF v Pentax DA

I'm considering these two and was wondering if anyone has had experience with boht of them. The Sigma is on sale right now for $50 less than the Pentax. I already have a Viv 75-210 S1 which I really enjoy but wouldn't mind a lighter zoom with AF. Any recommendations?

hi, like all sigmas it is very prone to sample variation. The one I had I wouldn't have kept if I been given it for nothing (I'm serious, it was very very soft). I picked up the pentax rebadged samsung 50-200 very cheap and it is brilliant. it softens a little around 200mm and I always use it at least 1/2-1 stop down but it often amazes me how good it is for a little & cheap lens. So for me,spend the extra money

I prefer my Pentax 50-200 over my Sigma 70-300 over the common range. The Sigma seems soft at the long end and contrast needs to be bumped up.

Somewhere in this lens section, about 3 or so months back, I've posted my comparison shots of those two plus the Sigma 18-50 2.8
