"Huge upgrade, worth every $"4.0 starson by TonyCPhoto
Pros: Full Frame, Very easy to shoot Video, Big Screen, wide Viewfinder, Comfortable in my hands
Cons: some what expensive, missing some key video features,
Summary: I've had my camera since Christmas Eve and I absolutely love it. I've only shot Christmas pictures and a few portraits but it's everything in a camera I've been hoping for. I previously had a 30D and sold it in October to be ready financially when this came out. I was hoping it was closer to November but hey I have it now.
Most people interested in the camera has no doubt seen Vincent Laforet's Reverie, and since I've had the camera I'm been doing primarily shooting Video. It's as easy as turn on the camera, hit the Live view button, compose the shot and hit Set to start recording. I've taken the videos and made small products already in just a few hours of editing, No problems importing the video, everything looks amazing. I've been shooting with the 16 - 35 f/2.8 70-200 f/2.8 are usm and the 50mm f/1.8 and they all look sharp and great.
The missing parts with video is full control, you can't set Shutter speed, aperture, or Is independent of each other, It's on full auto mode you can use the back wheel for exposure compensation but that's only to +/-2 however the exposure lock on the top left of the camera works to lock the exposure even in video.
It's an easy firmware update that Canon is sure to do eventually.
The photo's in low light are crisp with annoying noise not appearing till at least 3200 ISO. The Full Frame is probably my favorite thing having a 16mm lens look like 16mm not 25.6mm (1.6 crop factor). Looking at the other two FF's, Nikon d700 and Sony's this is the best bang for the buck, Nikon's is only 12.8 MP but that's more than enough for 90% of prints. It's cheaper but no Video. Sony has around 24 but more expensive and not as wide of a selection of lenses and again no video.
Any Canon fan should look to upgrade if they are making photography/videography more than just a hobby,
