C70 need viewfinder . Rig might be work in many scenerio , but in documents styles work , run and gun rig and all attached accessories is nightmare .
When first c100 appear I got zacuto evf because first one had very bad evf , but it was nightmare working on wedding , when canon c100mk2 appear I straight away got 2 of them , do not forget there was no big difference still only 8 bit but EVF finally usable .
EVF in c100mk2 no issues when working with gimbal , stedycam .
Canon why not make version c70 with evf . I need 3 c70 , I am ready to pay extra for that . C100mk2 made a lots of money for canon , c70 can make even more just simply evf please
I'm in a similar camp here. We have C200s at work for our primary cameras, and got a C70 last year mainly for smaller/lighter b-roll shooting. The C70 is a great camera and would definitely replace our C200s in almost every way, but so often on shoots in bright sunlight it's next to impossible to see what's on the screen. I also sometimes find on a monopod it can be a lot steadier if you're able to look through the viewfinder and brace the camera against your head while shooting, though we don't shoot like that way too often.
I would love a RF-mount C200 replacement(C90?) that had an adjustable viewfinder on it like the C200. We have an EOS R5C on pre-order, and I'm excited to see how that camera fits into our shooting habits, especially considering it also has a viewfinder and may come in handy for b-roll in bright sunlight.
