Canon G15 vs G12 vs P7700 studio comparison tool

... and if size was only thing that mattered I would have kept G15 and sent back P7700 instead of keeping P7700 and sending back G15. And honestly, size difference is not that huge, I would rather have better VR, noticably longer reach, and better corners.

So if it fails try and try again until you get results you want to see?
