The move from the conventional CCD to a CMOS sensor structure with its accompanying electronics in the latest G15 has bought with it some tangible gains in user benefits such as full HD (1080P) video and a doubling of the maximum ISO available. We can also see from our testing that while the pixel count has increased some 20-percent there has been only a marginal impact on sensor performance.
This is a good result overall and when considering the G15’s other features such as the flexibility of the new high-speed zoom and reduction in size over previous iterations it’s a extremely well-balanced and attractive package. For consumers the choice remains whether to spend more on an equivalent micro four-thirds camera with a number of lenses to match the same kind of flexibility or whether to restrict that versatility somewhat by selecting a more compact model such as the S110. Alternatively, you could consider the G1X or Sony RX100, both offer superior low–light performance with only a small premium to pay in both size and price.

The Canon PowerShot G15 and Nikon Coolpix P7700 are two cameras with a long lineage (with the Nikon's being a bit harder to follow). The Canon PowerShot G-series and Nikon's competitive offerings have gone through numerous variations over the years, but haven't strayed far from the original design philosophy: a fast lens, manual controls, and expandability via system accessories. The thing that's changed the most has been how you compose photos. For a long time, both the G and P-series cameras tended to offer optical viewfinders and articulating LCDs. On these latest models, the G15 lost the flip-out/rotating LCD but retains the optical viewfinder, while the P7700 sports only an articulating display and has shed its viewfinder.
