It sounds like the metering still thinks there is a Canon lens on it, which has an aperture the camera can change on command. Not true with the Leica lenses..... the aperture is manual and the camera can not adjust it. How to fix it? Ask someone that has one..... Frank Filippone firstname.lastname@example.org Gene. Yep there are exposure problems. I have 6 Leica lenses and all give the correct exposure on my Canon XTi at full aperature, but when I stop the lens down, they all tend to over-expose. The more I stop down, the more over-exposure I get. I see this in both manual mode and with AE mode. It does not matter if the lens is 2, 2.8 or 4 wide open. they all give the correct exposure wide open. I have tried them on my friends 20D with the same results. David Young reports the same thing with is Olympus E3 and I think with his Canon 40D before that. So, there is someting going on that needs to be compensated for. The problem is that it is not a simple -.3 setting or something because the difference increases the more you stop down. That is why I only use my Leica lenses on my Canon for shots that I can take the time and view and make changes when needed. The focus confirmation part works out quite well. And the 24mm makes some quite nice photos on the Canon.
