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 red735i@earthlink.net 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.
