Jeff, here's my opinion on RAW vs. JPEG.....completely honest and unvarnished. If a camera company could make use of an A/D converter that could resolve a pixel's voltage down to the level of counting every single electron they should do it. I wonder how many that would be....a 16-bit A/D converter could distinguish between 65,536 distinct voltage levels, so would that be enough? 24-bit at 16,777,216 levels? If that meant a 100MB RAW file with a maximum burst rate of 1 frame every five seconds I'd still find a use for it. I would probably only use that feature for a few shots a year, but I would use it.
I do not understand why people are comparing raw vs jpeg. There is very little to compare, they have different proposes.
It's like cars, there are small cars, big cars, sport cars, trucks, semis... They all have an engine and they all use some type of gas. They just have different purposes.
I mostly use raw, but there are times when I need to shoot jpeg. I have gone close to 2 minutes at 8 fps. I sell jpegs and occasionally tiffs to my customers.
Raw files are more flexible but they are not "stable" files. Giving my raw file to anybody, including any other professional, and nobody else will be able to exactly match my raw image. Changing processing software changes the image. This doesn't happen with jpegs or tiffs.
Different formats, different purpose
