Pretty much a C 300 for about half price.

No RAW, and EF mount only with an adapter. I'm curious what the downsides of getting this camera and using EF lenses with it would be.

No raw: I find this to be a surprising omission. Is this something that can be cured with an update?

Update: It has internal raw recording now, and paired with an EF speedbooster, is a monster of a camera.

I purchased a C70 two weeks and love this camera.
I have been using Sony cameras for the past 20yrs with a a brief purchase along the way with some Canon cameras however always stayed with Sony.

A few months ago I sold all of my gear for a camera reset. When It came time to purchase again I was not even aware that Canon released the C70 in 2020 so after a bit of research I purchased the C70 and loving the image out off this thing plus 4 x audio channels plus...I'm lucky that they have been producing firmware updates and now the camera is a fantastic tool for my productions that I work on.

I also wanted a small camera that could be striped down for a gimbal or kitted out with an extra monitor etc.
