Most hand phone users are happy with their instagram picture junk, and this is far not enough to entice the crowd. Canon has become a complacent company.Peter Kroll, Singapore
Yep ... and along the dynamic range also the chromatic aberration. As non-picture quality related issues there are the consistency of the metering system and the overall system speed.
Anyway, coming back to the subject: No G15 for me. A fixed monitor is a deal killer to me. Second point: My G11 is far not as solid as I thought it is, judging from it's weight and feel. On mine as an example the optical viewfinder has massive dust intrusion. Everywhere the hands-on quality was praised, but the real world long term quality seems is a different subject.
With it's fixed screen I don't see the G15 becoming a success. In a year they'll have a G16 with articulated screen. Anyway, I am considering moving to P7700.
Canon is not anymore what it once was, IMO. The G11 I own makes good photos, but the build quality is not really what it seems first. Just two examples: Wobbly shutter button. The optical viewfinder had a dirt particle inside after about 3 months only.
