[LRflex] Re: Leicanon exposure problems

Hello Aram,
I use Leica & Contax glass on my Canon 10D, (as well as Canon), and most of the time I have the exposure-compensation dial set to minus 1, to get the correct exposure. This setting is easy and quick on the 10D, and if there is a lot of white in the frame, I set it all the way to minus 3, and after exposure I double check the histogram. 
No problem whatsoever.
Hope this helps.

With best regards,
Erich Kozak

Aperture priority or manual mode. Either one, same results. I also went back and used my old adaptor w/o focus confirmation and the results were the same. Just did another test using flash. The flash exposures were all very consistant until I stopped down too much for the flash to provide enough light. They then got dark. My problem without the flash is overexposure as I stop down. The meter in either aperture priority or manual is overcompensating for the stopped down lens and the more I stop it down the more it overcompensates with the shutter speed.
I am ready to return the camera. Does anyone know if the Olympus 4/3 cameras have this problem? Is there an focus confirmation for the Olympus camera yet? I don't see one advertised.

I finally got a focus confirmation adaptor and an eyepiece magnifier for my Rebel XTi and have been quite disappointed with its exposure performance using Leica R lenses. I just conducted a more scientific test and this is what I found. Using the 35-70/4 zoom, it meters dead on with the lens at f4. If I stop down to f-5.6 if is 1/2 stop over exposed. If I stop down to f-8 it is 1 stop over exposed. This is consistent with what I found out yesterday using the 50 when I was noticing some of my shots were over exposed and other were dead on. I am using either manual mode or aperture priority metering mode. Both do the same thing, obviously, since AE mode is just duplicating what the meter says in manual mode.
I don't remember this problem when I would use the school's original Rebel. 

Has anyone seen this?  Is there a solution?  (yeah, DMR or wait for R10).

Good Sunday Mornin', to you, Aram!
Hmmmm... I'm using the FC adapters with a 30D and find the exposures quite consistent. I use Aperture Priority mode only ... which (along with manual) are the only modes known to work with the adapters. Are you using AP or AE (Auto Exposure) mode? 

Cheers!
