Nikon lens on Canon body: Setting the aperture
Submitted by Ingemar Bergmark on Thu, 2007-01-18 11:40.This is a small pin you can make for adjusting the aperture when using Nikon lenses on a Canon body.
A friend of mine inspired me to make this, and I've dubbed it the "J-Pin". With the pin you can set an aperture of f/8, f/5.6 and f/2.8 (I haven't made actual measurements on the aperture values, but they are approximate).
