Ah, makes sense. I had figured the magnification, but the other units had me stumped. The unit does seem to have provisions for stacking another bellows to the front (which I don't have, nor likely need). It sure does get dim after focusing and stopping down. I think the FM with the red diode indicators for exposure approximation might be better. The meter needle on the FE is pretty hard to make out. Thanks a lot for the info.
