Adapter

Have I read some of these threads correctly. Is there an adapter that allows FD lenses to be used on our EOS cameras?

There are, but they tend to either degrade IQ or not allow focus to infinity. In general, not really worth adapting IMO.

To expand on the previous response... Yes there are adapters, but they have to use optics if the lens is to focus to infinity, and the optics cause a lot of loss of image quality.

Some people remove the optics in order to use macro lenses or super telephotos, both of which are might not need to be focused to infinity very often.

It's sort of ironic, just about any other vintage lens from any other manufacturer can be adapted for use on EOS, except for Canon's own early lenses.

Thanks. I was planning on possibly using a couple for macro work that I might be getting from a coworker. I had several of these lenses when I had my AE-1 back in the early 80's.

If you get a FD to EF adpater that has no glass in it, you can use those older macro lenses, but without infinity focus.

I have an old 50mm FD lens which can be used for macro works (without glass adapter) but the working distance is way too near. As mentioned above by themadman using FD EOS glass adapter you willl lose significant IQ, light and it will act as TC. Just not worth it.
