Re: G3 speed?

The long exposure frame substraction has nothing to do with noise reduction at high ISO. It kick in as you make a long exposure, even at high ISO. Its goal is to avoid hot pixel frequent in long exposure, not to tame the sensor noise common at high ISO.

Put a cap on a lens and take a picture with a shutter speed of more than 5 seconds and even go up to the slower speed of 30 seconds, you'll see what that function is for.

NB, you will be horrified to see how many hot pixels are populating your picture !

It is because of the hot pixels extraction process. You can turn it off in the menu, but you will have red and blue pixels in the picture. It was the same in the G1 also.

If what you say it's true, and the processor is the same, we could have similar high iso quality jpegs in G1 too versus slover processing speed, just updating the processing algorithms. I could live with that.
