A new spec list for the Canon EOS 5D Mark IV is making the rounds. We don't put any stock in and it's likely just clickbait. We have rated this [CR0]
Canon EOS 5D Mark IV will have a 28mp full frame sensor, 12 fps, Dual Pixel autofocus system AF III, crop mode (or clipping) to 1.3x, to simulate the sensor size of the EOS 1D old series, or 1.6x , to simulate the size of Canon's APS-C sensor, anti-technology flickr; sensitivity from 100 to 204.800iso, 409,600 in extended mode.
Canon EOS 5D Mark IV c: 18MP full frame sensor, very useful for optimizing the performance at high ISO and burst. Dual Pixel III AF autofocus system with 61 points of focus, ISO sensitivity from 100 to 204,800, 4k video.
It's Friday, have fun with it. I've been emailed a bunch of times about the above spec lists and just like Keith over at Northlight, we feel it's nonsense. There will not be a “prosumer” 4K DSLR from Canon in the next round of updates. The EOS-1D X Mark II will get the 4K video, but that's beyond the prosumer market.
We won't be linking the original source, but Northlight has if you're curious.
