Hello everyone, I have a DP1 finder which sticks at about f5.6, a bit like a very heavy f stop indent but a little too severe to give smooth operation any longer. I have had some good DIY repair tips from this digest already but I don't think I'm doing it correctly because nothing looks like the helper describes it, so I have left it alone for fear of ruining it altogether. Does anyone know of a repairer in England who would be able to repair this problem. I've already tried Grays with no luck. The track is fine and a good replacement is hard to find. Hope somebody can help. Best wishes. Ed.
