This camera looks awesome. I owned the Sony NEX 7 for awhile and loved the camera itself. My only annoyance was Sony's Raw converter program was absolutely horrible and slow as molasses. Are you referring to Sony's RAW convertor software for the computer? or the actual RAW files from the camera?
It's Sony's "Image Data Converter" and it's absolute cr*p, except for the color reproduction which I think is great. I adopted Adobe Lightroom so I can process my NEX files in a reasonable way but I have had a lot of trouble to get good colors from Lightroom though and only recently think I've got it right. LR is a bit too fussy IMHO.
I still prefer DPP for my Canon raws because it has better support for in-camera features, saves changes directly to the raw files and is database or sidecar independent - and its clean interface suits my shooting/editing style.
