Incorporating key Cinema EOS video tools in a mirrorless-style body, the Canon EOS C70 features a Super 35 DGO (Dual Gain Output) sensor for capturing images with up to 16+ stops of high dynamic range. The innovative DGO system combines two separate gain readings for each photodiode on the sensor, emphasizing saturation in bright areas of your image and lowering noise in darker areas. Video resolutions include DCI 4K capture at rates ranging from 23.98 to 60 fps, plus high-speed options up to 120 fps in UHD 4K and 180 fps in cropped 2K.
Pro video functions also include unlimited video recording, Dual Pixel CMOS AF autofocus control, a motorized ND filter, RF-mount, a BNC timecode input/output connector, and built-in dual mini-XLR audio inputs.
The EOS C70 was also the first Cinema EOS camera with a Canon RF lens mount, that enables you to use Canon's line of fast, reliable RF lenses with advanced coatings and image stabilization.
