Wrap-Up From Engadget
If you demand that an $800 camera contributes to your photography with “extras” like high ISO, interchangeable lenses or exceptional macro prowess, then the G1 X has rivals that are perhaps more worthy of your consideration. However, having used the G1 X heavily for a few days, we can look past its weaknesses — even its underwhleming battery life and uninformative OVF — and admit we’ve become quite attached to it. Our affection has everything to do with the large sensor, fast lens and the overall physicality of the camera — its design, feel, and the accessibility of its controls. If you want a tool for capturing high-impact images, and not necessarily for adding impact to your images, then the G1 X ought to suit you fine.
Preorder from B&H for $799 (Expected to arrive March 5, 2012)
