Regarding the OM to digi adaptor, yes the lenses do work, although = most of the functions are not communicated to the camera, of course. = This was an adaptor that was designed for Olympus Microscope and I think = astronomical work, so the exposure is somewhat easier to control. I have = one of these adaptors, and have had it about a year maybe, it is good if = you have some long lenses, such as a 400mm say, and cannot afford the = Digital lenses. OM lenses can be used on the E1 and E500, although the = lack of communication makes the exposure very hit and miss, especially = in fast moving sitautions you cannot beat the digital lenses, albeit at = an additional expense, of course One other factor to seriously consider when using the OM system = lenses, as excellent as they are, of course, they are not designed for = digital cameras, so aberrations may manifest themselves. If you dont = know what I mean then I suggest you take a look at the Olympus digital = site which explains the concept of digital lenses vs analogue. It really = is better to buy a few new digi lenses, and maybe keep a long tele, say = a 300 or 400mm lens as a standby, or use them when there is no way to = get the same with a normal digital Olympus lens you have. They will give = good images on the E1 or E500, but not quite as you may expect each = time. =20
