It's been stated numerous times in this forum that certain manufacturers overstate their ISOs in order to make their cameras seem to have better noise performance than they actually do.

True

It may have been stated numerous times, but it's been equally wrong each time, too.

Bertrand Russel would disapprove How wouldyou even know?

The OP provides evidence that the EM5 is an outlier - strangely enough massively in its favor, resulting in some interesting false-positive publicity, per his later post. This is one of my favorites, where the EM5 obviously performs as good as physical limits allow for its format. Does a neutrino travel faster than the speed of light? The Italians think so

While we are at it, who said 'You can fool all the people all of the time if the advertising is right and the budget is big enough'?

Right.

Jack - you're totally, 100% off base here. You seem like a smart guy, so I really hope you'll go through the reference material with care.

It is a complex subject, but I am certain you are intelligent enough to understand it.

I would caution you, however - keep an open mind and don't go into this journey convinced that you're right, because it will take you a lot longer to reach the correct conclusion, which is that you are 100% wrong.

I know, because I made the same journey, and did it without keeping an open mind. My journey took longer than it should have because I was convinced I'd figured it all out. I hadn't.

And neither have you - yet...
