So, not bright sun, uniform unchanging light, ... I post processed both shots identically in order to show the difference, not to avoid blowing out highlights, which I could have done. The question is more about why the exposure varies, which I have seen in a lot of my shots and am just wondering if others experience that And can I attribute the 1 stop variation to not covering the eye piece Or if there is an issue with the 5D? I'm not sure I know exactly how the evaluative metering works, Canon is not very specific on how it actually works. The problem seems to be the worst with higher F stops. I thought the metering was done prior to taking the picture, so I'm not sure why a higher F stop would matter, as the metering is done wide open.
------------------------------------------------------------------------ ---------------- Yes, light entering through the eyepiece would alter the exposure and make it stop down since the meter is now getting more light. Easy way to check. Set up the same with sun to your back. Check the exposure as you are looking through the eyepiece. Then move your eye away so sun comes into the eyepiece. But now hit the exposure lock button, and now check your exposure. I would almost guarantee it will be 1 or more stops off. Best way around this, use manual exposure when the eyepiece is not covered.
