And I've been telling people that it is an excellent camera. The reviews, too, bear this out. Actually, I think the G9 does. And I’ve been telling people that it is an excellent camera.

I actually bought this camera, and took it back after finding out it didn't support RAW... What is the point, since you can get the PANASONIC for less with all of the features...

You’ll have to pick up this magazine to get to the meat of the article. The relevant part here is he Timothy measures the dynamic range of the Canon Powershot G6, which has RAW capability. At the lowest ISO 50, the measured usable dynamic range is 10 f-stops for RAW, and 7 2/3 for JPEG. At ISO 400, he gets 5 2/3 f-stops for JPEG. (Smaller sensors have a larger drop off of usable DR at higher ISO.) As I explained above, there is almost no difference due to the increase megapixel between the G6 and G7. I think the conclusions show two things: 1) RAW has more usable dynamic range than the best JPEG at the lowest ISO in the G7 2) One can speculate how almost worthless the signal-noise is at the high ISOs: 1600 and 3200 on the G7. Meaning that the inclusion of high ISO in the G7 is pure marketing. The exclusion of RAW in the G7 is pure business (selling more dSLRs). In the latest issue of Photo Techniques, there is an article “Measuring Digital Dynamic Range” by Timothy Edberg.
