In Live View mode, you can magnify the image to check focus. It shows a great amount of detail, at 30fps. How is the camera achieving this?
Surely it must support sensor windowing, which has interesting implications. Essentially it means that EFS mode for lens support can be turned on but the mount itself doesn't support EFS lenses. Why did Canon make this decision?
Also, moire does not exist in the live view mode, it's only when the image is down sampled to 1080p that it's introduced. Clearly the onboard CPU isn't designed around video, so isn't capable of downsampling to H.264 1080p without pulling a dirty trick or two. But what's interesting is that the sensor itself outputs very happily to the LCD a down-sampled moire free image, which can be windowed right in to an almost per-pixel level on the 3:2 screen without any compression artefacts. Just like the GH1's live view which doesn't suffer from the dreaded 'mud' and AVCHD compression, the 5D's H.264 falls a bit short compared to what the camera is REALLY capable of.
Clearly Panasonic's and Canon's CMOS sensors are leaps and bounds ahead of the current onboard image processing chips.
These cameras are just one upgrade away from total greatness.
