G15- Almost 3 Stop Advantage Over Predecessors

After doing some raw evaluation of the G15 on DPP (Canon's Digital Photo Professional raw converter), it's become apparent that the new processor and sensor are doing a much better job than the previous G series cameras- such as the G12 for example.

The near 3 stop advantage is based on a combination of raw performance, and the increase in the brightness of the lens. In raw I'm seeing about a stop and a half improvement in useability in the raw images over the G12- add that to a stop and a third advantage optically, and you've almost got a 3 stop advantage when you shoot the same lower light scenes that require wide open apertures.

Base ISO on the G15 is very similar in this regard to its predecessors in terms of noise. But dare I say the new lens is also sharper in the corners (compared to same f/stop) and the slight increase in resolution of the sensor give the G15 the ability to make some very impressive 16x20" prints.

When conditions are ideal, this camera will make some fine looking 20x30" landscape prints for your wall at base ISO.

More to come on the G15 as I evaluate further.
