I have the Fotasy FD adapter for my 50mm F1.4 Canon Lens and have been using it for a while on my E-PL1. MY E-P3 was away for repairs and now that I finally have it back I can't get the adapter to fit. If I start turning it to lock it into position, it begins to grind and the resistance is too great. In addition, the grinding causes paint to shave off which could get on the sensor. This also happened on the first E-P3 I had. The one I am using now is a replacement. Has anyone else experienced something similar? Any recommendations for a good adapter with aperture control?
