Excellent, this sounds like the camera I have been wanting any manufacturer to release, a pro/semi-pro mirrorless camera

The X-T1 probably fits the bill, and the A7/A7R if it had faster focus, but they didn't really meet my needs. Hopefully Samsung does something to really make it stand out from the competition. I will probably buy it regardless since I am invested in Samsung, but would be nice if it were class leading in some ways.

I never let my money spent on a system's flashes, lenses, etc., keep me tied to a system.
I went from Canon to Nikon and now Samsung.
Yes, it cost me each time but not as much as one would think.
But I switched to fill my needs at the time.
Because of this approach my needs are being filled and I am a happy camper without that cloud hanging overhead that prevents so many photogs from switching.
And may I state if Nikon was more concerned about me than concerned about canabilization of their DSLR business, they would have made an APS-C mirroless camera, and today I would still be all Nikon.
Today I shoot Samsung and have no regrets
A big Splash in the market place would occur if the NX1 can save a RAW file for every Auto Mode shot.
Believe me, this alone is enough to make my NX30 a PRO camera, and to get many Pros on board.
