If you look at the back wall in that M3 shot, see the size of those "blocks" that make up the wall like a collage? I think it is just extreme JPEG compression in the camera - look at the settings and find out how to set the JPEG to "High"..

To get an idea of what this camera should be capable of (plenty):

That should take less time than an oil change

- now get us some good pics of that M3!
