FD to PK adapter

Anyone have experience with the Canon FD to PK adapters ?

Any quality loss , etc ... If you remove the lens from the adapter , it becomes a small macro tube ? ( I assume )

Thank you

I believe it works out to be about 13mm of extension tube with the registration distance difference and the thickness of the adapter. Anything wide angle is going to be strictly close up use only, but you'll be able to get some distance with longer lenses.

You will find that we have tested it quite a lot with and without glass in the adapter-"club":

With glass it is like a converter. Not a good one, but not as bad as you would expect from a converter that looks like it is only made of two cemented glass elements.
Without glass it is mostly useful for longer focal lengths and macro. A short focal length give you a very small working distance. I've used it a lot on the Canon FD 200 mm f4 macro 1:1 lens, where I can focus to about 2.5m, which is enough since one would anyway mostly buy that lens to use it as a macro.
