Review on Pentax SMC DA Series 50-135mm f/2.8 ED IF SDM Telephoto Zoom Lens for Pentax DSLR Cameras: Enhance Your Photography by Nam Le Bao ᠌

I wanted to buy this lens for a long time, having studied many sites, having read excellent reviews, I bought it, now I regret the money spent, the fact is that at the short end 50mm lathers terribly, I tried the same picture on two cameras, starting from 70mm and up to 135 is normal , the focus ring has a backlash, which is also a little annoying, maybe I got such a copy, I don’t argue, but sorry star, and even for that kind of money it’s too much / bought from an official dealer / pentax is not the same as compared to its former masterpieces, so think carefully before you buy
