It's just little thing but it bothered us, so we decided to make it.

With the new FD mount, you don't have to use the "toothpick trick" to jam the iris handle on the back of the lens. The mount itself has a little groove to catch that handle when you screw the lens in.

New orders of Extreme will see this mount if they order FD. We have been shipping quite a few already silently but I don't know if users noticed.

Happy New Year!!!!
