Here is the OM-D with grip and 90 finder next to the OM-2n with the same.
The grip feels very good. The dials feel pretty much identical to the camera dials. It does make the camera quite a bit heavier, so if you are looking for something lightweight it might not be the best accessory, but I'm glad I have it. The only downside is that the rubber covers might be easy to lose if you don't put them in the grip storage areas properly.
A few other comments.
At Shinjuku Yodobashi black was outselling silver 2:1, but they said that's still a pretty good showing for silver considering their customers. Other stores probably aren't split as much.
Anyone pre-ordering after the first couple days of March didn't get their camera today. Quite a backlog for a camera, especially an Olympus.
The new IS seems quite impressive. Not going to post any photos, but just some random crap in my apartment at 1/13 of a second and 150mm came out looking surprising well.
Haven't shot with it too much yet, but overall I'm liking it very much. Huge improvement over the GF1. I have a feeling that I'll want to keep a GF or Pen line camera to go with it when I want something more compact.
I LOVE LOVE LOVE seeing clipped highlights in the EVF. One of my favoriate features of the camera so far, turning it on was a PITA. Left eye shooters might have a hard time with the back dial location. I can use it, but my thumb rubs against my nose a bit. The whole view finder is still easily visible.
The new shutter sound is awesome. Much more muted. I don't have an E-1, but it seems E-1 like.
The color of the silver body matches the 45mm, not the 12mm. Only people looking for it would notice it though.
I'm surprised how much it looks like the OM2n when I have them next to each other. I think the shape is even closer to the OM4. I'm curious to see if people think I'm shooting a classic camera. For normal people I think the different might be hard to tell apart.
