Hi, I'm pretty sure it's an unchipped adapter. And it's a 28-200 lens, not 20-200 as previously stated. Good advice and that's definitely starting to work for me re- aperture and then the internals on the camera. I'm also a bit dubious on quality of the old analog lens with the new digital camera. I'll spend more time during the day tomorrow and see what I can come up with but if it's not killer, I'm not lugging this thing around in my travels. My back already hurts enough:) Anyway, thanx for the much-needed help. Really appreciate it. gm
