Canon G15 vs. Canon G1X

I just checked on DxO comparing the G15 and G1X (large sensor):

G1X:  about 2 stops better than G15 for noise and at higher ISOs about 1 2/3 stops better for dynamic range, but at lower ISOs the dynamic range is the same and at the lowest ISO the G15 is better

The G15 has a fast 28-140mm f1.8-2.8 and the G1X has a slow 28-112mm f2.8-5.8, so at the wide end the G15 is 1 1/3 stops faster and at the long end it is 2 1/6 stops faster.  In other words, especially as you start using the longer end of the zoom range the G15 will be using ISOs that are 2 stops lower than the G1X.  So, compare G15 ISO 200 to G1X ISO 800, G15 ISO 400 to G1X ISO 1600, etc.

The G1X is much bigger and heavier so for my uses of the camera it was not really in the running.  It was interesting to take a look at the G15 vs. G1X results on DxO though.  That G15 fast lens really makes a huge difference.
