As mentioned in another thread, I've got a converter for using a Minolta MD lens on an Eos body that is supposed to focus to infinity, but doesn't because it's missing a corrective lens. All I know about the missing lens is that it's 25mm in diameter and (judging by the side of the flange it fitted into) no more than 3mm thick at the rim. I'm guessing it's a concave or concavo-convex lens of some sort. Unfortunately there's no maker's name or other info on the mount and I don't have the packaging - I got it second hand on ebay from a seller who didn't know much about it. If anyone has one of these adapters, it would be very helpful if you could check the packaging, instructions, etc. and see if there's contact details for the manufacturer. Or if you're equipped to test the focal length that would be wonderful! I suspect that it would probably be cheaper and less trouble to buy another, but I'm not in any hurry, I'd prefer to explore other options first. If possible I'd also like to get hold of an adapter for using more recent Minolta and Sony-Minolta (Dynax) lenses on the Eos. I can't seem to find anyone selling them, but maybe there's someone somewhere that does. It would need to have some way of setting aperture, since most of these lenses lack manual controls, but I've seen this done with other mounts so I'm sure it's possible. I should mention that I'm in the UK, so will need to order from sellers who ship here. Thanks!
