When such a > lens is mounted it will disengage the camera AF motor. But this is only for new bodies which recognise this. Older bodies will still spin the AF screw. This will probably not be as noisy as powering a lens from it, as the screw will be under minimal load. This is sort of my point - the ability to take USM lenses is already there and it wouldn't require any camera mods to work. Of course it would work *better* with a body designed specifically to do it, but you'll still be able to stick your FA*USM lens on an LX, PZ, or MZ body and have it work as well as that body can drive it. dave - This message is from the Pentax-Discuss Mail List.
