Originally posted by Designosophy The M50/1.4 truly is a fantastic lens. I have no legitimate complaints about it. Unfortunately, I somehow bent the filter ring on mine ever so slightly. I have no idea how. Just a few weeks ago filters went on like butter. Now there's a flat spot and nothing will screw on. No idea how or when it happened.
I have a Pentax 35-105mm 3.5. When I won it on a bid, it didn't state it had been dropped. The lens shoots great, but was unable to put on any filter or hood.
So, following some instructions, I was able to using a wooden dowl to gently pound it back into shape with no problem. I think if you do a search you'll find some pictures with the setup to do.
