According to the manual, the M Raw uses 11M pixels, so what I should have probably asked is if this is equivalent to a full RAW file shot with an 11m camera?  I had a 5D, which was only 12M, and it still took beautiful photos, but it sounds like there is some degradation of the data to get the 20M pixel photo down to 11.  Which probably doesn't make it worth it.  Thanks for the help everyone.


To give a specific example. Until recently we used a 5D ( 12.7mp) and a 5D mkii (21mp).

The 'sRaw' on the mkii at 10mp gave significantly higher resolution than the 12.7mp camera.
Rather surprisingly it also appeared to require more processing time from the computers.

I've found an example, both at 200% 'cos at 100% on the web I'm not sure you'll see any difference. These are both originally raw shots, converted to tiff, then jpeg'd for the web. No modifications including no sharpening.

I tried using M RAW to shoot real estate. In my workflow I heavily push/pull the highlights/shadows so I need all the data in the file I can get. The very first test shoot with M RAW and I was very disappointed. I simply didn't have the flexibility as I had gotten with full RAW. My advice: never use anything but full when shooting RAW.

I always use full RAW except when I do an occasional timelapse movie, in which case I shoot sRAW or mRAW.

When I got my 5D2 I was hoping that M Raw would be as good as full Raw downscaled in post.
In the end it seems that in camera downscaling is pretty bad compared to that done on a computer. I know it's a complicated process so it doesn't really surprise me.

When I shoot for the newspaper I use sRAW because 1.  They are much smaller, and 2.  If I need to edit, still gives me more freedom than jpeg.  All other times I shoot full RAW.
