I imagine a non glass converter would render better but does anyone know the focal range limitation, if it's not infinity how far out is it?
I've got much FD glass and recently bought EF bodies. Bought a glassless adapter, particularly for longer lenses and close up work. Took some time to mount a number of FD lenses on the rig to see what range there was.
The adapter lengthens the flange to film distance, essentially acting as an extension tube. The effect on focusing distance then depends on the focal length of the lens (since the extension of the adapter is constant). The longer the focal length, the farther out you will be able to focus.
Don't have figures or formula at hand, but I doubt you'll get anything w the 15, and only essentially macro with the 50.
Sorry I can't be more specific by lens -- but you'll see after you get your adapter.
