Hello,

Do the Canon G9 and SX100 have any notable technical differences in
their sensors, photo contrast, optical distortion, dynamic range,
etc. I
wonder if their side by side photos comparing the results.

I realize they are quite different models. I am just wondering if the
G9's sensor is significantly different than the other's (except the
resolution of course).

G9 has 1/1.7" sensor (9.5x7.6 mm). SX100 has smaller 1/2.5" sensor

hmm .. so that would result in lower noise level in G9 I presume. Also,
I wonder what does sensor size do to the contrast and dynamic range of
the captured image -- or do they depend on the quality of a sensor?

(7.2x5.8mm). In area, the sensor in G(9 is roughly 1.7 times larger
than the SX100. The 1/2.5" size appears to be the general size of
sensor in most compact P&S cameras.

Great sites! Thanks a ton for the references, they are a nice read. They
clarified many doubts I had earlier.
