I did read your previous post on lens speed, but one thing that wasn't pointed out is that an f/2.8 lens on a 4/3 sensor will have a very different bokeh at that aperture than an f/2.8 lens on APS-C or full-frame camera (film or digital). The DOF gets increasingly narrower with a larger sensor, so I suspect that f/2.8 on M4/3 is actually closer to f/4 or f/5.6 on my Canon 5D. Yes, you can still throw the background out of focus but you have to be close to the subject or using a long lens, or both. As someone who shoots a lot of portraits, that aspect of a fast lens (the narrower DOF) is as or more important to me than the amount of light it lets in.

I love everything about it... except the glass. Where's the 20-25/1.4-1.7? Where's the 40-50/1.8-2.0? Without fast primes like that I have no interest.

So far I'm impressed with the form factor and concept, but underwhelmed by the lens selection - at least initially. IMHO the "revolution" Olympus is predicting this camera will start won't happen until they can make fast primes that rival what's available for DSLRs. I for one won't buy one until they have a 25/1.4 and 45-50/1.8. If I have to make significant sacrifices in terms of IQ, low light and DOF capability, and focal length selection in order to own one of these M4/3 cameras, I won't buy one. Hopefully in a couple of years the 2nd or 3rd generation M4/3 models will be out along with some fast primes. Then they will be truly revolutionary.
