FotodioX FD-EOSR-PRO Reviews

incompatible with breech lock FD only works with nFD bayonet

By Keenan
Rated 1 out of 5
Date: 2025-06-26

This adapter is incompatible with breech lock FD lenses. It blocks the locking ring on the lens from turning. I cannot mount any breech lock FD lens to this adapter, so it is useless to me. I am requesting a return. Also incompatible with sigma FD lenses- the barrel of the adapter is too narrow it will not accept any of my sigma lenses. For many lenses, the rear of the lens will need to extend slightly into the adapter. This will not work with any lenses that have a protruding rear element. The actual build quality feels good. But this is not an FD adapter it specifically doesn't work with the original FD series lenses. This is an nFD adapter. They should call this an rf to nFD adapter if it only works with the later nFD bayonet mount version. I expect even with nFDs, there would problems with certain lenses not fitting into the narrowed opening of the adapter barrel.

Maybe I just got a dud?

All my FD lenses have some weird double edge ghosting halo effect happening for subjects just out of focus. When I use them without this adapter that goes away. Will be returning this one unfortunately.

Why is the blue aperture ring even necessary when you can adjust the aperture directly on the FD lens?
Asked by: A. R.
Some FD lenses do not have a manual aperture ring you can turn on the lens with your hand. For those lenses you would use the blue aperture ring in the adapter.
