One camera that's putting out good reviews on the Micro Four Thirds side is the new Olympus OM-D E-M5 (see it here on Amazon). A nice upgrade for PEN shooters. The in camera stabilization is a big plus for people who want to use older or aftermarket lenses. If you're looking to get one sooner than later, there's one OM-D (Black) with 14-42mm available for normal retail price via eBay, but ends in 50 minutes. Find it here.
One of the great things about shooting with a Sony NEX-7 or Micro Four Thirds camera is the ability to use just about any lens on the market. Not having autofocus in a lens is one thing, but without Image Stabilization, those adapted lenses can be tricky to shoot hand held.
The new Olympus OM-D EM-5 solves that by offering what they call a 5 Axis IS at the sensor (not the lens). Unfortunately in order to get the aperture working for my EF lenses to an M43 body, the expensive solution is the RedRock Micro Live Lens EF Adapter (seen here). Along with what could be the best EVF available on the market today, and all starting under $1K (body) this will be a very very popular camera. In fact it's already at the top of the Amazon new camera list (seen here).
Vintage camera styling seems to be a popular trend. Olympus did a great job bringing back some influence with it's PEN cameras, and now the new Olympus OM-D EM-5 design carries on some influence from the old OM series. I wonder if die hard Oly PEN camera fanboys are excited about the new retro design? The new sensor for Olympus amongst other new tech is supposed to be outstanding. For just under $1K, the Olympus OM-D is already available on pre-order (click here for prices).
