I've not seen the degree of error Daryl mentions but certainly MF lenses
on my Canon 5D don't meter accurately. But I've never worried about it
too much since I tend to use "expose to the right". I adjust as
necessary to push the histogram to the far right and avoid using the
meter if I can (although I often use it as the first test exposure)
