Summary: I really don't know how can this camera has some bad review. I am the real user and giving honest review here. I think those people got so unlucky to get a defect one or they just wrote fake reviews. I've been using Olympus since I started taking picture. My brother and cousins are using Nikon and Canon so I can compare them with Olympus. They are all good in their own way but Olympus is my choice because I like the style, function and quality.
Summary: It's small and packs a punch like a DSLR. I switched over from a DSLR to this to downsize and lighten my loads, but I found myself shooting more and having more fun with this camera than I would have expected. It's a lot of fun and you never really have to think to hard about whether or not you should take your camera with you or not(unlike my old Pentax K-5, which was already a fairly small DSLR).
Top micro 4/3s camera at under $1K... and probably beats many at $2K.

Summary: Tough to go wrong with this camera. I have had the DSLR Canons and the older 4/3s Pen. This is a huge step up from the Pens and it keeps a much tighter body than the bulky DSLRs. You can take this biking, hiking, skiing and not feel the load on your shoulders. I also shoot a lot of movies and the quality on this is stunning.
Summary: What a great camera. It replaced an Olympus E-410 for us, and is smaller, lighter and very much more responsive. The autofocus difficulties of the E-410 are gone. (And as it aged the battery compartment of the E-410 kept popping open during use.) The moveable LCD display of the OM-D 3-M5 is great and very useful. The only drawback is that the lens mount has changed, and we decided to get new lenses rather than buy the adapter. I would recommend it to anyone.
