I had the OM 28/3.5 before buying the Distagon 28/2.8. It was a nice little lens (though I like the the Distagon much better), and you're right that it's sharp in the corners without having to be stopped down much. When I did need to stop it down for the DoF, though, there was a pretty serious drop-off in detail and contrast from f/11 to f/16. I don't know if it was from diffraction or what (this was on my original 5D with big fat photosites), but I pretty much considered it unusable at f/16. YMMV.
Shouldn't be a problem for me - I'm on 16 MP APS-C, so I generally avoid f/16 anyway. It might matter some when I get to FF, I suppose.
I'd love to get the Distagon 28/2.8, but it's another $300-400 and just so big. I might change my tune when I get an A7 or similar, especially if I sell the G28 to fund it.
