So, I had a bit of a hands on the new Mk 2 at a local pro shop (our studio is in line to get one of the first ones in the state, sometime in the next couple weeks, maybe even next week). I have to say, the build quality feels substantially better than the Mk 1. It feels closer to the D700 or D300 in terms of build (which were always a bit stouter than Canons prosumers). The prism seems more robust from the outside, but isn't much brighter or clearer than the Mk 1 and the body seems well sealed. The new LCD is definitely a big step up from the smaller one on the Mk 1, and is far clearer. The menus are certainly prettier, but take a little getting used to when switching from the older 5D. They are the same menus from the Mk3, they just have prettier animations and look substantially better on the HD LCD. Aside from the obvious stuff we've already read in reviews, here are things that really stuck out. The shutter sounds far nicer than the old camera. It sounds closer to the cha-chink of a D3 than the Mk 1, except with a crazy futuristic compression noise (no other way to describe it, has to be heard to understand). It makes it just feel like a far more advanced camera than it's older brother (which it is). ISO noise: Is phenomenal. 6400 looks roughly like ~1000-1250 on the old one, maybe better (which is very, very usable, like all day). I haven't had a chance to really nit pick, but zoomed in all the way on the LCD, there wasn't much noticeable noise. 12k starts to get much worse and 25,600 is for emergency use only (equiv. to about 3200 on the old body). I only got a chance to play with it for about 15 minutes, but I could tell that Canon has done well on the sensor. The evening before, they had an entire seminar on the new camera, and my coworkers (avid Nikon D3 shooters) got to see images in large print and blown up on a monitor and they were shocked. Apparently noise handling is better than the D3 (yep, I said it). It does get the same barring at extreme ISO's that the current 5D gets, but if you need to shoot over 6400 at f1.4 or 1.2, you should probably consider a flash or leave the cave your in. Video: Looks very good. Shooting at 1.4 through live-view is a trip. Oh, and the new lens baby composer on HD video is absolutely crazy. Quite a good time. The controls feel clunky at first with the video, but it gets a little easier. The face recognition works surprisingly well in video mode as well. I was able to get it to lock at f1.4 with someone bobbing in and out of frame. I have a feeling it'll unlock some pretty cool video opportunities that just weren't available to consumers before this. I do have some images floating around on a drive in the studio somewhere, but i'm not sure where my boss dropped them. Your just going to have to take my word for it for the time being: Canon has developed a phenomenal camera. When they release a smaller MP full frame sensor in a pro body, the ISO noise race will be completely over. This technology is fantastic, and flash photography is quickly becoming superfluous.
