If you want to use it in stop-down mode in Av mode, do this:
- Remove the lens from the camera.
- Use a piece of tape (ScotchBlue™ Painter's Tape is my favorite for marking) on the camera, near the lens mount, mark the location of the lens locking pin.
- Attach a piece of tape around the lens barrel.
- Set the aperture ring of the lens to the largest number (e.g. F/22).
- Attach the lens to the camera while looking into the lens, notice when the lens closes down to smallest aperture. Put a mark on the tape around the lens barrel, aligning with the mark of the location of the lens locking pin.
- Drill a small hole on the lens mounting ring at the mark. You may need to remove the mounting ring to do this. It's pretty simple, just a few screws. The new hole is similar to the existing hole, just about 1/2 inch to a side. The size of the hole is not critical, as long as it's equal to or larger than the size of the existing hole.
If you want to use the lens in stop-down mode, lock the lens with the new hole. If you want the original functionality, when attaching the lens to the camera, depress the lens locking lever pass the first (newly-drilled) hole and lock the lens with the original hole.
There, you have it both ways.
