JPEG profile

Areas of focus look pretty good in JPEGs through ISO 200; then color noise and noise-reduction artifacts kick in. You can see how much detail you lose on the fur as well as the softness of the details on the tape measure. I wouldn't recommend going above ISO 1600.

Like the S110, the G15 inexplicably blew out exposure on the book page.

At ISO 80 the camera produces good detail without aggressive sharpening.

The camera produces natural-looking sharpness at ISO 100 as well.

At ISO 200 you still get decent detail, but it also starts to get a little soft.

Out-of-focus areas, raw vs. JPEG

This detail comes from an out-of-focus area of the previous image. You can see how the sharpening in the JPEG produces some contouring and graininess in the out-of-focus areas, but the raw trade-off is softness in the sharper areas.

ISO 800, raw vs. JPEG

At higher ISO sensitivities, you can really get some better results shooting raw to minimize color noise, improve edges, and decrease fringing.

By ISO 1600, photos have that processy, special-effect look when viewed up close. However, they can still print pretty well as large as 13x19 if you use the raw files.

Highlight recovery

There generally isn't a lot of detail available in blown-out highlights, but there's enough to fix sky and clouds.

Overall the G15's color rendering looks good; it's a little cool and contrasty, but not as bad as from the S110.

Center sharpness

The lens tops out at f8, but remains relatively sharp throughout most of the aperture range.
