digifan: I'm sorry but the E-PM2 does have an accessory port AND a flash socket, you could have mentioned that.
Using the NEX in the wild over the weekend and major observations are the noise of the shutter, I won't be sneaking shots with this camera for sure..note to PIs out there...this is not one for you!Also, the lack of support by both Adobe and Sony has been very disappointing as I have been told by both to "just wait a little while as the camera is new and hasn't gained support yet." That's nice, I spent $500 on a camer and can't process my pictures because I choose to shoot in raw...or .arw as Sony chooses to call it.Camera otherwise seems great and has been quite a lesson in futility. I have early adopted before and never came across this lack of compatibility issue. I may be late to this party, but someone really needs to step up on this.
Bottom line: As of today, if I were using film, one hour photo would be faster.
