They're equal brightness at 1/4 and 1/5, so 1/3 of a stop. I didn't really think 1/3 of a stop would matter to much to this discussion.

1/3 stops seems a lot for cameras of the same make - you would expect that Olympus would want its cameras to perform consistently - inconsistency within a brand puts the wind up people, but they get used to the foibles of the evaluative metering on different brands. For instance, you frequently read that Nikon 'tends to overexpose'.

I did the same test outside a week ago. The difference there was pretty well unnoticeable, so I suspect it's more a quirk with white balance or something. It was on auto.

In practical usage there's pretty well no difference between these two cameras. (Which could be partly why Oly went with such highlight room on the OM-D).
