We were told a short while ago that Canon would only be announcing a pro broadcast camcorder ahead of IBC 2018, which begins later this week. That still appears to be the case.
Apparently, the camera is aimed at being a replacement for the Canon XF305 and focused on broadcasters. The camera will shoot 4K at 60 in 4:2:2: 10bit. Interestingly, the camera will also add a third control ring to control the IRIS.
The lens will be a 15x zoom L series lens, which would be a shorter zoom range than the XF305’s current 18x zoom.
