It's heavy , indeed but I've been happy with the 1DX2 on the Zhiyun gimbal with 11-24 and smaller. It just manages the 70-200 2.8 II but tele on gimbal walking is tricky. I'm curious what you like/dislike with your setup. I can say I'm pleased with the 4K60 I've shot and 1DX2 video in general. I am wondering also how an R would be on my gimbal if I get it as a backup camera.It's all about who they are building these for. The EOS R made great strides for Canon, ironically in the video realm most of all. With 4k30 plus Clog and 10 bit 422 out over HDMI, that was a huge leap for Canon who has otherwise been either reluctant or unconcerned with video competitiveness since the 5D2. The 1DX2 is still my go-to rig for stills, with a 5DSR for critical work. But my 'second job" has afforded me basic commercial video work on a one man operation that MILCs are so well suited for. The 1DX2 does gorgeous 4k and 1080p, but I'd love to have that in a much more compact frame for run-and-gun video as the 1DX2 does not easily balance well on gimbals like the Ronin M. I'm waiting to see how stripped down the EOS RP is from the R in terms of video before I make the call, because I have no expectation the "PRO model" will be better suited with a higher res sensor and thereby (most likely) even greater crop. I can't even get 4k out over HDMI on my 1DX2 which is still very frustrating. The ability to record externally to SSDs is precious and as much I love the look of my Canon big-rig... it sucks not being able to go external.
