My 35-105 Pentax zoom ring will lock up. It will work free but it is a pain, esp if i am shooting something important. Any thoughts on a replacement. Have a Pentax *istDL. I like the zoom range. Sigma has a 17-70 f2.8-4 but at about $350, well. Thought about a sigma 28-135 f2.8-4 as well. Thoughts.
