mRAW is demosaiced and downsampled. You still have most of the benefits of RAW (dynamic range, white balance), but you have no control over the demosaicing algorithm. If you do night/astro shots (like I do), you see lots of hot pixels that show up in long exposures (I see many more than I used to now that my camera body is three years old); these ideally should be cleaned prior to demosaicing; otherwise they'll "smear" and cause a lot more damage than just one pixel.

7D goes in the wrong direction
I really appreciate CANON’s achievements in terms of small pixel/high picture quality but while I don’t hear anybody shouting: ”Please give us smaller pixels!” CANON IS JUST DOING THAT!!!
Did those 5000 photographers that have been interviewed during the development process of the 7D really want an APS-C Sensor with even higher resolution!?! I bet they didn’t.
From what I have seen so far I think that with a 12 Mp APS-C sensor the 7D could have got the same ISO capability as the Nikon D700. That would have been something CANON!
Who cares for the extra 6 Mp that nobody really knows how many of them the glasses can resolve…

First of all, even don't start to whine that this is another review that is not owner's review. I am owner of Canon 350D, 40D and expect long time for a better camera and I read all the camera tests and reviews. I have read all the specification of this camera and have explored the image samples. So I have my own right to my opinion and publication as a message to Canon. (as I will never buy this camera).
To my view this cameras is a huge mistake. According to number classification this should have been FF camera. I can't believe, that Canon has interviewed 500 profesional photographs and they all wanted APS-C sensor camera in a body heavier than Mark 5D II. This is ridiculous! For a common user this body is too large and too heavy. And megapixels are too many. I just don't see any reason why somebody should purchase this over 5D II. Images are noisier.
Wouldn't it be nice to poduce FF camera in a small and light body with 10 or 12 mpx for a user who is not going to make big posters ? How long to wait?
