Though all the reported problems with SDM failures, my most favorite zoom from Pentax to this date is Pentax DA* 50-135mm f/2.8. It is a dependable zoom with prime qualities. Though slower in speed, it rivals well in event photography with my Pentax FA 77mm f/1.8. I truly hope that my copy stays strong and not run into any SDM failures.
I took it out last weekend after the rain and the zoom works well with Pentax K-x and AF in SDM is quiet and locks on target responsively. I desire on longer reach for the zoom in nature walk as 135mm is just too short in reaching objects in a distance.
