just to clarify -- this adapter will allow me to mount my Canon lenses from my AE-1 to my olympus om-d MFT camera?
The Dot Line adapter will work on all FD lenses either the old breech lock or the newer bayonet FD lenses. Your AE-1 uses these lenses. It will adapt to both the Olympus and Panasonic micro four-thirds mount.
I have used mine without problems, but you need to read the instructions that come with the adapter since the pin (screw) on the adapter must engage the lens stop down lever correctly or you cannot stop down the lens. DO NOT USE FORCE until you get it right. Then mount it to the camera.
As a side note I painted my screw flat black for appearance as well as the screw head.
The quality of the mount is good considering the price.
Enjoy your FD lenses on the Olympus/Panasonic
