No 14-bit RAW or AdobeRGB; boo-hiss!
from Canon's website:
(...)Shooting and Recording Modes Including 14-bit RAW + JPEG
The PowerShot G1 X Mark II offers a host of shooting and recording modes ranging from fully automatic to fully manual, plus Full HD movies and full-resolution high speed continuous shooting. The camera recognizes 58 shooting situations, automatically optimizing settings for achieving the highest quality shots on the go. Alternatively, you can exert complete creative control over the look and feel of your images. 14-bit signal processing, just as in EOS-series cameras, gives images notably rich detail and smooth gradation, and RAW images are available in a choice of 3:2 or 4:3 aspect ratios. Compared with 12-bit processing, 14-bit offers a 4x increase in RAW data for a visible impact, giving images rich detail in both highlights and shadows as well as smoother, more natural tonal gradation for outstanding image quality.(...)
Thanks for that, didn't find anything about 12 vs 14 bit raw after a quick skim thru the manual.
Hopefully it has good enough signal to noise ratio to warrant 14 bits, otherwise 12 can be adequate.
