I also had Gelegehneit the new Sony RX100 Mk.2 test and the image quality is the level of detail with regard to Sony and dynamics - especially in Raw - not to the G1X zoom. However, the difference in most of the subjects are not huge and whom minimum size and higher speed are very important, is probably with the RX100 have more joy.
But measured at almost APS-C-sized sensor (same height as APS-C but smaller width) and the 4x zoom lens is also the G1X is not too large. Quite the contrary, if you look at how deeply build appropriate zoom lenses with APS-C system cameras. Also that the maximum open aperture decreases greatly at long focal lengths, is (unfortunately) of physics and is not owed by the Kitobjektiven.
The greatest weakness of the G1X is their (lack of) speed. Between two JPG images pass 1-2 seconds, which may already be an eternity in fast-moving objects. In RAW, the waiting time turns out even longer. Auto mode should as far as possible avoid, because there's more seconds are added, in which the camera performs any calculations. If you want automatic, then you better choose a setting P.
I would also be a 3: 2 Sensor prefer, as with cameras with a large sensor is usual (and like him, for example, the Sony RX100 has). The 4: 3 format is just typical for small compact cameras. But probably not enough lens to cover the full width of the APS-C format. The 3: 2 setting reduces the resolution then to 12 MP, which is barely noticeable but in practice because of the good lens resolution.
What something is bugging me in the operation, that after taking a picture you can not interrupt directly to the push the rearview function. If you have for example set as rearview duration 4s, then reacted while eating the Zoom button not, unless you only once more pressed briefly the shutter button halfway (then again 1s waiting period). Otherwise the handling of the G1X is absolutely exemplary. All functions you need are reached quickly and efficiently. It lies perfectly in the hand and it is simply a pleasure to shoot with her. Except for the lack of focus peaking (colored edge enhancement) in manual focus I miss nothing.
The autofocus is very accurate, but not the Allerschnellste. As for motives that remain at the same distance, I turn to the automatic focusing often on manual focus (hold timer and press MF) to order at subsequent shots each time must be re-focused (MF fine adjustment menu off beforehand). Manual focus you can possibly be automatically readjusted via the AF button.
Disturbing is that you always have to switch to Macro (depending on the focal length under 1m) per hand for recordings at close range (and then back again). Only the slow auto mode manages to switch itself. In addition, the minimum minimum focusing distance is very high. Unfortunately, absolutely not suitable macro (without conversion lens).
Conclusion: no camera for snapping quick. But who takes time for them, they rewarded with the best pictures in this camera class.
Addendum: I have to confess. I changed because of the size and the speed but now for Sony RX100 II. I felt the difference in size between G1X and my DSLR with zoom lens for everyday use but too small. The Sony is simply a good compromise between the 1 / 1.7 inch fraction and the APS-C cameras. Yet a third point has led me: Out of laziness and time constraints, I often only JPEGs and let the automatic control, and since Sony has the nose in difficult lighting conditions slightly forward. One has rarely intervene in the exposure or spot metering endeavor than the G1X.
