Olympus OM-D E-M1: First Impressions Review

Some of us where seeing here a replacement, or upgrade to the OMD-M5, and now, yes, it is one, but with 4/3 mount, not M4/3 mount. So, those who have the full package of M4/3 lenses will be disappointed, specially because you can mount a M4/3 with 4/3 lenses via a small adapter, but the opposite does not work.

So, again we have a new 4/3 camera, with same, just updated, sensor as the OMD-M5. Is there something to be excited now, I doubt it, except those that waited for this one. If I had the choice at the moment to buy a 4/3, GX7 in M4/3 is the way to go. I do not want to carry dslr’s around anymore. I use NEX, but GX7 excites me. But like always, there should be something for everyone. If I was Olympus, I would put exactly the same camera with M4/3 mount on the market, and I am sure it would sell, maybe even more in M4/3 than in the 4/3 mount shown here.
