Hello folks, so today, just about 30 minutes ago I performed my first lens surgery. I'll let you know I'm not well versed in these things, I've only had my GH2 since December, but I'm having a lot of fun. Anyways! I have been using a lot of adapted lenses and when I first got into adapted lenses I was a terrible buyer. Anything cheap I bought right away. So, I purchased an Auto-Kentar 35mm f2.8 AR. Problem was, the Kentar was stuck wide open even though the aperture ring worked as it should. So, I shelved the lens for quite sometime. However, today I was feeling adventurous and broke out two pairs of tweezers (1 big, 1 small), 3 screwdrivers (2 phillips, and 1 jewelers flathead), a flashlight, and a pair of latex gloves. I proceeded to unscrew the mount first. After that point I really had no idea what I was doing. I removed the aperture spring, effectively de-clicking the lens(as I'd heard the spring is what makes it click) just for fun. I also removed the pin in the mount which needed to be depressed to move the aperture. With my tweezers I also removed what looked like lint or dust. Finally, I fixed the aperture by removing and repositioning the aperture ring. I had to take the hook which was hanging off of it, and match with the perforation in the internal ring which surrounded and controlled the diaphragm. This solved the issue of only being able to use the lens wide open. So I effectively de-clicked the lens, made it easier to turn, and fixed the aperture! I had nothing to lose as it was not functional before. Anybody else has stories of lens surgery they'd like to share? Also, did I go about this wrong and in a way that would damage the lens? Any suggestions on how I could have done this differently or perhaps safer in terms of the lens? All comments and stories are welcome!
