I read numerous reviews about the OM-D E-M5 before making the purchase (from another vendor as Amazon now charges sales tax to CA residents). It has far exceeded my expectations. Beautiful to look at (I went with the silver) with its retro styling, very comfortable to hold, and and an incredible amount of customization. The IBIS is as good as people say, and the pictures are stunning especially when used with good glass. The kit lenses (14-42, 12-50) are ok, but you won't get the benefit of the great sensor with them. I'm using my OM-D with the Pany 25/1.4, Oly 45/1.8 and Oly 60/2.8 macro and am amazed at my results. And if you are on a budget, definitely take a look at the Sigma 19/2.8 and 30/2.8 being sold together for an unbelievable package price from the famous NY dealers. Both of them have excellent image quality and for 2 bills for the pair of lenses, you can't beat the price for 2 high quality primes. I just ordered the combo package as well though I will likely use the previously mentioned 3 on my OM-D and the 2 Sigmas on my Pen E-PL2 bodies (1 visible and 1 IR).And yes, after getting the OM-D, I realized I didn't want to lug around my heavy arsenal of Nikon bodies (D300, D7000) and lenses any longer. The image quality from the OM-D with the primes listed above far exceeds what I ever got from my Nikon setup so I had no hesitation in selling it all. And with my new setup being so small and light, I find I am much more likely to take it with me. The OM-D and Pany/Oly prime lenses have renewed my interest in photography and I am enjoying every minute.Note: The resolution, noise levels, and dynamic range of the OM-D are very comparable to the newest high end Nikon crop sensor bodies. It still doesn't compare to Nikon Full Frame bodies, obviously the sensor size does limit that, but given the cost of a FF body and FF (FX) lenses, not to mention the weight, I think 90% of photographers would be fine with this set-up.I hope this is helpful.
