I didn't even think it possible but my 50L is clearly underexposing by about 1 full stop no matter which camera it is mated to. I have used it and witnessed it on my 5D, 1D2N and a friends 5D2. Have any of you experienced this with any of your lenses? I am now part of CPS as of today so hopefully Canon can figure this out for me!! John
I haven't experienced this with any of the copies of the 50L I tested, neither on 40D, not on 5D and 5D II.
Are you sure this isn't some vignetting, or the selected metering mode?
The first copy I ever tried of the 24-70L had bad vignetting, same with the first 85 F/1.8, but never seen it since, other than any expected vignetting.
Kind regards, Wim
