I had an xt and the metering was fine I rarely had to change the exposure on it, the only time I had to change it was in the snow / somethind dark etc. But since I went to the 20D I constantly and I mean always have to set it + 2/3 for the exposure to be right. Its like that in all the metering modes, every lens I have, bright, dark, sunny, dull, indoor, outdoor it doesnt matter it always does it
not really a big deal I just leave it on + 2/3 but I am wondering why is it like that? everything else functions perfectly without issue.
it has the latest firmware on it as well
