While looking for information on cleaning a Nikon 50mm Series E I came across a link to this site in the comments of an article. It may have been posted before but it's worth bookmarking. This guy adds every camera repair or modification link he can find, in several languages. It's a great resource. http://www.4photos.de/camera-diy/index-en.html
Wow. Incredible what the guy has put together. Thanks for posting this. There's enough stuff there to keep you occupied on rainy days for the rest of your life!
