5dmark3_front_real-224x146This seems to be the real deal. What would normally have been announced very late tonight or early tomorrow (east coast time), looks to have been leaked ahead of time. Canon Rumors has posted a list of specs and a few images that we can almost safely assume are official, since the announcement is less than 24 hours away. These images are of the professionally photographed variety, likely what we would be seeing in a press release. They also perfectly match that photo we reported on here awhile ago. Here is the complete list of specs and my thoughts below.

Canon has increased sensitivity by two full stops in stills mode, and one stop in video mode. Why the discrepancy? It could be a mistake, or more likely, there is some sort of noise reduction applied to the very high ISOs in stills mode, and it's impossible for the image processor to keep that up in real time while also downscaling the image in video mode. One of the benefits of taking a large image and scaling down to 1080p is actually that noise becomes less distracting, so it's interesting to see Canon limiting the video ISO.

Some of the notable features: Dual Card slots that we discussed here before, larger 3.2" screen, HDR and Multiple Exposures Mode, Comparative Playback function (not sure exactly what this does yet), Vastly improved autofocus, 6fps shooting up from 3.9fps in the 5D Mark II, 100% viewfinder coverage, and a new Mic input, which was revealed in the earlier leaked photos.

Thankfully it looks like this camera will be using the same batteries as the Canon 5D Mark II, Canon 60D, and Canon 7D, so if you've got a few of them lying around, you might want to hold on to them.

The only mention of video in these specs is 1080, so it's clear we will have to wait a little longer for the final specs on that. While the camera might be capable, I'm just not sure we are going to see 1080 60p. Same with clean HDMI.

The back of the camera has certainly changed dramatically. The new 5D Mark III now resembles the Canon 7D in more ways, and adds the photo/video toggle and start/stop button. Menu and Info have been moved to the top left, and zoom has been moved to the left hand side. The new Rate button is still a mystery, but as an educated guess it seems like it will be a function for rating and sorting photos.

I will include a comparison of the old 5D Mark II for reference with the other leaked photos. Also of note, the 5D Mark III is shown with the new Canon EF 24-70mm f/2.8L II USM, but that will not likely be a cheap kit if they release it as one since that lens is over $2000. It also looks like Canon will be releasing a new battery grip and a new flash.

Stay tuned for the full release and detailed video specs.
