Ok!!! Could this concept DSLR camera actually be the Canon 5D Mark III? The concept DSLR camera sports a full-frame 35mm sensor, 4k-video capability, and will support the full EF and Cinema lens lines. With the 1D-X already out, it looks like the next big DSLR announcement might just be this one — I’m just waiting to hear them call it the 5D Mark III.
