The thing IS, if I optimize my K1 settings (exposure adjust, and jpeg compression) I can shot 27 images bursts... When I compare IQ of 3 different JPEG 22Mpix setting at 100% on screen, I can't see the difference of IQ between the medium compression setting and the lowest compression setting. So the whole trick is to get the exposure right, then it opens up further burst rate capability on the K1. And that's a very interesting thing.... because if I look at the Canon gear, they do achieve higher frame rate and buffer
but not with 36Mpixel no-compression quality level. I had never tried the mid compression level on my K1, but the files are a lot smaller, and I cannot tell the difference of IQ even zoomed at 100%, so I guess the compression algorithm is very effective. So for a landscape setting, I could use RAW to max out on the dynamic range and possible shadow recovery in post, but for a concert in low light high ISO I'd use the 22M JPEG with mid compression level it would allow me plenty of room for bursts. Maybe, shooting exclusively in RAW isn't taking the most advantage out of the K1 camera. Anyway, if you shoot at ISO6400, you've already lost 6 bits of dynamic range due to increased ISO setting + sensor ISO invariance, so even if you shoot RAW at ISO 6400 you won't get more than 8 bit depth per channel, = same as if you shoot JPEG in terms of possibility of post process the image.
ISO | RAW RGB bit depth | JPEG
100 | 14 bits | 8 bits => shoot RAW, buffer depth 11 frames
200 | 13 bits | 8 bits "
400 | 12 bits | 8 bits "
800 | 11 bits | 8 bits "
1600 | 10 bits | 8 bits "
3200 | 9 bits | 8 bits => shoot JPEG 36M ***, buffer depth 23 frames
6400 | 8 bits | 8 bits => shoot JPEG 22M ***, buffer depth 25 frames
12800 | 7 bits | 7 bits => shoot JPEG 22M **, buffer depth 27 frames

Originally posted by normhead Thanks for the links, those are shot at ISO 3200 and 6400 where you don't get benefit of RAW anymore... Shooting JPEG on a K1 would still give better IQ than with K3, and still 25 burst depth.
