Canon releases their new Full Frame Mirrorless camera system, the Canon EOS R comes with a new R Mount, with new lenses but it can also adapt all previous Canon lenses using their adapter. They have a very fast and precise Dual Pixel AF for very accurate video autofocus performance. It only has a single SD card slot, 4K video has an 1.8x crop. It does have IBIS neither but the lens based stabilization such as in the 24-70mm f4 kit lens is quite good. The positioning is about in the middle between a 6Dmark2 and a 5Dmark4. The new Dual Pixel CMOS AF sensor provides high autofocus performance and low light ability. The new mount also provides very high bandwidth allowing for new features in the lens for better performance. Canon emphasises that the EOS R system is designed to be future proof, this camera is the start for this new mount, possibly this could mean they might soon also provide more video centric camera without the 1.8x crop in 4K shooting, I'd hope with video features like in the new XF705 Pro Camcorder such as 110/160mbitps H265 HEVC for 4K60 HDR HLG 10bit 4:2:2 recording internal to dual SD card slots too.
