Heres what i have used for years, a Vivitar 2X macro focusing converter ( with the elements removed). This gives you a nice focusing helicoid like extension. The tube is about 45MM collasped and grows to 60MM extended. I had lots of luck on a 300 EDIF screw drive lens. Glass can easily be removed with simple household tools. If you have to remove an element by force, EYE PROTECTION is a must. Tubes are usaually available from KEH Camera. I have both Nikon and Canon FD. They think more of the Nikon mount price wise. Heres a quick idea what can be done with a FD 300MM lens. The Vivitar collasped brings the inf. focus down to about 9 feet. The target size is similar to a post card, 31/2 inches X 5 inches. See photo two for hand held shot. The Canon MFD is about 91/2 feet and its moved to about 31/2 feet, see photo three. The target size is about 1 1/2 inches by 2 inches. Focusinf with the Vivitar focus ring of course moves you closer as desired. I had to break the final (4th. element ) in each one i did. I believe Carsten on FM was able to remove all four.
