Thanks guys!!
Got the GXR, M Module and EVF today. Put the CV35/1.4 on it and started taking photos around the office. The build, ergonomics, user interface, and customizability of the GXR body is fantastic. I specially like the customizability and UI. The camera seems to have been designed by people who actually use the camera.
That being said, I'm having difficulties manually focusing the CV35/1.4 in both peaking modes, even with the magnify on. And specially with the lens wide open. I haven't been able to nail down focus wide open even on stationary subjects (i.e. books). I wonder if the lens suffers from focus shift when shooting wide open. I don't recall images being super duper soft though, when shooting wide open with the M9. I guess I need to do some tests when I get home, and look at the images on a computer too. When I stop down the lens to f2.8, it gets MUCH better.
To my eyes, peaking mode 1 is not very good. The shimmer doesn't shimmer enough, and it's white. I think the peaking on my old NEX3 worked better. Mode 2 seems to work better than mode 1, but still doesn't seem quite as effective as the NEX's peaking. Maybe Ricoh will issue another firmware making the peaking better.
That shutter sound is nice!! Sounds like the K-5's shutter. Soft and silent.
