Last week, Canon officially unveiled its first RF-Mount Cinema EOS camera: the 4K EOS C70. In addition, the company also debuted a new EF-to-RF speed booster, which allows users to take full advantage of full-frame EF lenses on the C70’s Super 35mm sensor.
The EOS C70 is the first Canon cinema camera with an RF mount. At its core, the EOS C70 features a Super 35mm Dual Gain Output (DGO) sensor that Canon claims offer a whopping 16-stops of dynamic range by reading each photodiode at two different gains: one to prioritize saturation and protecting detail in highlight areas, and the other to suppress noise in the shadows.
The camera can shoot up to 4K/60p or 2K/120p (with a Super 16 crop), but if you deactivate the extended dynamic range, the camera can capture up to 4K/120p or 2K/180p.
Other notable features include dual-pixel autofocus, “coordinated” electronic IS, support for Canon Log 2 and Canon Log 3 Gamma, two SD card slots that can record different codecs and resolutions at the same time, two mini-XLR audio inputs, a full-sized HDMI port, and a built-in ND filter system that puts 2-, 4-, 6-, 8-, and 10-stop options right into the camera body.
With regards to cooling, Canon put a huge fan behind the LCD screen that reportedly does not impact weather sealing, and keeps the camera cool irrespective of how long you’re shooting for.
Here’s a closer look at the new camera from all angles:
In addition to the camera, Canon has also released a new optical adapter called the EF-EOS R 0.71x that essentially is an EF-to-RF mount 0.71x speed booster, a first from the company.
The adapter is made specifically for the C70, attaching via the standard flange and then securing to the camera using two screw-in brackets. As you would expect from a focal reducer, the EF-EOS R 0.71x optical adapter can squeeze the entire full-frame image from EF lenses onto the 4K Super 35mm image sensor of the C70, while simultaneously increasing sensitivity by one stop as it gathers more light.
The Canon EOS C70 is already available for pre-order for $5,500 and is scheduled to ship in November while the EF-EOS R 0.71x won’t arrive until December, but you can pre-order yours here for $600.
