A reader sent me this DIY solution for using modern Nikkor G lenses on manual Nikon film SLR cameras like the FE or FM2 (it solves the lack of aperture ring problem):
1. You need a Nikkor G lens, a Nikon film SLR camera and a piece of string:
2. Link the string to the aperture pole of the lens, then pull it and hold it:
3. Hold the lens and mount it on the camera:
4. Hide the string (it looks stupid):
5. Press the preview button to check whether it’s works or not:
6. Press the lens release button and rotate the lens for getting a smaller aperture. Look at the position of the fronts on the lens before and after rotating. I held the preview button and I got f/2.8 by observation:
