Canon announced and unveiled the 5D Mark III earlier today. The camera has met with mixed optinions (they almost always do), but this appears to be a step in the direction that most people have wanted. In particular, the new AF system addresses a key weakness of the camera that has been harped on in the past.
I'm very curious to see how this camera performs. While the pixel count hasn't gone up compared to the previous incarnation, there appears to be promise for much improved high ISO image quality and improved dynamic range. Only time will tell.
