The original Canon FD rear lense caps have a stop you need to remove so the cap goes on untill you hear it lock. The third party cap I have converted did not have a stop maybe that is the problem. On my 50mm FD lense as I put on the modified rear lense cap the blades open all the way. You select a diaphragm value of your choice and if the lense is ok the blades will close and open accordingly as you manipulate the lever that protrudes most. If you have an old FD lense with the silver ring nothing happens as you put on the cap, but the blades should move when the diaphragm is not set to its most open setting (3.5 or 2.8 depending on the lense) when you manipulate the lever. If you have a lathe or acces to one, the conversion of a rear body cap takes about two minutes. |
