Olympus is forcing us to step over to m43 or to another brand with their today marketing policy. I regret that.
Personally when I look to the 43-products, it is a marvelous phographic system. But some refinements, evolutionary or revolutionary like a 43 OM-D body is welcome. The same can be said about lenses and accesories. Let's not forget the Zuiko 43-lenses are belonging to the best. Some refreshment is needed. That's all. I'm not asking a knew camera model every six months.
I own an E-P2 with some m. Zuiko's and yes you can make beautifull pictures with it. But still it's a different phographic tool...I mean like the E-5 for instance and the sturdy 43-lenses. Putting mine 35 - 100 mm or 12-60 on mine E-P2 is more than one step backwards.
