Regarding the GXR EVF focusing concerns....I recently purchased the GXR w/ 28mm module and evf and have downloaded the latest firmware for the module which allows for the peaking mode and high pass filter focus mode on the 28mm module (which is what will be available for the M-Module). I'm an M shooter and I have not had a problem focusing with the EVF. I have set-up my function buttons so it me to quickly get in and out of the focus and magnification modes. As said before, it's definitely not the same as focusing with a rangefinder, but it is usable and fairly quick. My problem with the EVF and I'm assuming I would have this same problem with something like the NEX 7, is the blackout that occurs when hitting the shutter button. For shooting street, it just doesn't work for me which is why I think the fuji X100 is on to something. I plan on buying optical VF's for the GXR since I use the snap mode for street anyway and it will rid myself of the black-out.
