from the articles I've read on various camera brands, and from the brands and cameras I've owned, I've had a nikon D80 and D300s, a sony NEX5 and RX100, canon GX1. I'd have to say now that I own an Olympus four thirds, i'd say olympus has to be one of the most under rated companies out.. A lot of other companies are getting a lot of credit in the media and in reviews for their camera kits , but i couldnt be happier with my olympus, I'd rate it highly against just about any kit out there on the market. the quality i'm getting is what i'd expect to have to get from a pro full frame kit... friend of mine had an EOS 5DII and he traded it for an olympus. less bulk and weight for the same quality of photos..
the EM5 wasnt a super expensive kit compared to whats on the market, i wasnt expecting it to be as good as its turned out to be. So i'd rate it as good value for money.
