I'm a bit confused currently regarding the 1DX III. According to the spec on the
German Canon page and
DPReview the 1DX shoots at 5496*2904 at 60 FPS in RAW video!? I had thought it was only 30p, or am I missing something?
The rumored specs for this body are 8K raw at 30 FPS, where I assume 8K just means roughly 16 times as much as FHD (just as 4K usually means UHD and that's 4 times as much resolution as FHD) So, doing the math:
5496*2904*60 / (16*1920*1080*30) = 0.96
The actual throughput would be almost the same as the 1DX III currently handles. In that regard, the other numbers don't seem all that crazy. And the 1DX III isn't really crippled, it just can't do higher resolutions because the sensor is only 20MP. Mind you, this is based on my impression that the 1DX IIi does 5.4K 60p RAW video.
I would assume the 14/20 FPS means 14 in FF mode, 20 in crop mode. Why would it refer to viewfinder and LiveView - those are virtually the same in a mirrorless body. And that's absolutely realistic, as 14*45 = 630, which is 38% more more than the 14*32.5 of the low cost M6 II can do with an older processor and smaller body (worse for dissipating heat).
20 FPS at FF resolution seems to much, unless that's reduced Bitrate and no AF, like the 8K video option would be. But who would want that?
II get the impression that Canon is working on a ton of bodies that are all fairly modular and which configurations are the ones we'll actually see released could be quite different from the rumors. In any case 8'm surprised about the resolution, as previously we heard THAT Canon wants to regain the high MP crown and had talk of 73 and 82 MP sensors... Fun times ahead!
