Neenko. I work in Television and we have a very large green screen at our studio, so a 4K camera would be nice. What I really want it TRUE 1080p, unlike what Canon is currently offering the new 5D3 which is still up-res'd 720, so the image is soft.
And YES, Canon is continually letting down the video people. With all their Digic 4 releases, they never fixed the moire / aliasing problem that started with the 5D2. The subsequent 7D, T2i, 60D and T3i all had the same un-fixed video issues.
Then canon released the C-300. At $16,000, it's truly overprice especially considering it does not have 10 bit compression nor 1080p 60fps. Canon does not have a mid-range video solution (between $3K to $6K) that is satisfactory.
The 5D3 comes out, and the video is STILL up-res'd 700 lines which results in the same soft image.
What most video people wanted in the 5D3 was just 3 things 1) no Moire 2) no aliasing 3) True 1080p HD. Canon did 2 out of the 3, but still didn't do the 3rd major request of TRUE 1000 line HD.
For the Stills crowd, the 5D3 is great. For the video people, Canon is still playing games and people are getting really tire of waiting. That's why they need to release the 4K C-DSLR soon. For me, 4K isn't super important. I just want good 2K resolution, which Canon does not currently offer except in the $16,000 C-300.
