Canon launches EOS C70 4K RF Mount Cinema camera

Canon launches EOS C70 4K Cinema camera in RF Mount

Canon has launched the EOS C70 cinema camera. It is the first Canon EOS cinema camera in the RF mount.

The EOS C70 has the same 4K super35mm sensor as the EOS C300 Mark III

Following are the salient features:

Sensor: Super 35 mm Dual Gain Output (DGO sensor).

Sensor size: 26.2×13.8 mm

Resolution: DCI 4K upto 120fps, DCI 2k (super 16mm crop) upto 180 fps

Recording modes: DCI 4k (4096×2160) and UHD 4K upto 50/60 fps at 160-260 Mb/s in H.264 Long GOP/XF-AVC 4:2:2 10 bits. It can also record upto 120 fps in DCI 4K and UHD 4K.

It can also record DCI 4k in H.264 Long GOP/MP4 4:2:2 at 10 bits upto 50/60fps. If needed then one can also record in 8 bits in 4:2:0 colour space.

Log: Canon log 2 and Canon Log 3 gamma curve is available.

RAW: No. Unfortunately, there is no provision for raw in this camera. Even though a similarly priced EOS 200 has rawlite mode, Canon has decided not to provide rawlite in the EOS C70 camera.

Audio: 4-Channel 24-Bit 48 kHz LPCM Audio

EVF: Canon hasn’t included an EVF and has made it optional.

Connector: 1 HDMI connector. No SDI. There is USBC, BNC connector and a 2.5mm LANC control

LCD: 3.5 inch articulating LCD with 2,760,000 Dots is provided at the back of the camera.

ISO: 100 to 102,400

Auto ISO: The auto ISO helps when you are moving from one room to another and the light levels are lower or brighter and the camera will automatically control the ISO to ensure smooth transition. Earlier we used to use the aperture to help in increasing or decreasing the light. That used to take away focus from framing.

Processor: DIGIC DV7

EOS iTR AF X autofocus function: The EOS C70 is the first Cinema camera to offer EOS iTR AF X autofocus function which uses head tracking algorithm using deep learning for better distance measuring and tracking. So when a person turns his/her head the camera would notice and track accordingly.

Dynamic range: 16+ stops

Mount: RF mount

EIS: Electronic image stabilisation in the EOS C70 promises better stabilisation by coordinate control when used with RF mount lenses.

ND Filter: 10 stops

Recording media: 2 SDXC/SDHC card slots

Battery: BP-A 60 or the smaller BP-A 30 as well as AC power adapter.

Weight: 2.6 lbs (1.17 kg)

Price: $5499 USD

Availability: November 2020

This clearly is an attempt by Canon to provide a lower entry point to people into the cinema camera ecosystem. For Canon RF mount is the mount of future. So despite launching top end cinema cameras in the form of EOS C500 Mark II and EOS C300 Mark III in the EF mounts, Canon is now swiftly moving into the RF mount. The EOS R5 mirrorless camera is a a very capable one and Canon would definitely be brining that 8K sensor to a cinema camera sooner rather than later. The Canon C500 Mark II was launched in 2019. So in 2021 when the postponed 2020 Tokyo Olympic games is likely to take place, Canon may bring out a top end 8K Cinema camera with the EOS R5 sensor in the RF mount. Nevertheless, the EOS C70 RF cinema camera will likely act like the earlier C100 cinema camera which was highly popular. The C70 has all the codecs which will help in quick turnaround as well as will be broadcast approved. C70 will likely help in all the regular corporate productions, music videos and documentaries. Since it is limited to 4K resolution, the high end documentaries and productions who want to finish in 4K will prefer the C500 Mark II over this and some are now only asking for RED 8K. Combining the C70 with a EOS R5 may be the way to go for many independent productions.

Ready For Action: The Canon EOS C70 4K Digital Cinema Camera Packs Cinema EOS Imaging Features Into Still Camera Ergonomics

The First Cinema EOS Camera with an RF Mount, this New Compact and Lightweight Model Features a Super 35mm Dual Gain Output (DGO) Sensor, DIGIC DV7 Image Processor, and 16+ Stops of Total Dynamic Range

MELVILLE, NY, September 24, 2020 – Canon U.S.A., Inc., a leader in digital imaging solutions, is excited to announce the company’s first-ever RF mount Cinema EOS camera, the EOS C70 4K Digital Cinema Camera. When the Canon RF mount was first introduced, imaging professionals began to dream about the possibilities that this revolutionary mount system might provide them. One request that Canon consistently heard was to put an RF mount on a Cinema EOS camera so that future lens performance could capitalize on the short flange depth. Just two short years later, those wishes have come true with the new C70 camera.

The unique design of the EOS C70 camera puts a significant emphasis on operational convenience for the end-user. The small form-factor, weighing only 2.6lbs., allows the camera to be easily handheld and dramatically enhances a videographer’s mobility, providing a seamless bridge between the EOS and Cinema EOS families for cinematic applications. Cleverly designed, the camera features a slim, motorized ND filter unit – having a mere 6mm depth – that is built into the short flange back of the RF mount. The motorized 10-stop ND filter provides users with the flexibility to control exposure while keeping the desired depth-of-field and capturing images that feature the desired level of bokeh. Thirteen customizable buttons allow users to select from more than 80 functions to be assigned based on individual preferences.

“The Canon EOS C70 camera is truly a special tool that will undoubtedly satisfy and delight a variety of users on the search for a high-powered piece of video equipment,” said Tatsuro “Tony” Kano, Executive Vice President and General Manager of Canon U.S.A.’s Imaging Technologies & Communications Group. “In today’s fast-moving, ever-changing world of filmmaking and content creation, versatility is key, and the EOS C70 will provide a familiar form and feature set to our entire spectrum of imaging customers. We are eager to see how creatives use this tool and the projects that come from it.”

The camera features Canon’s innovative and next-generation Super 35mm DGO Sensor that further extends the high dynamic range and lowers noise levels by reading out each photodiode with two different gains. One gain prioritizes saturation – protecting detail in highlight areas – while the other suppresses noise in the shadows. The result is an image with up to 16-plus stops of total dynamic range, clean, rich shadows, and vibrant highlights in up to 4K/ 60p or 2K/120p in Super16mm Crop mode. The EOS C70 camera also features Canon’s recently developed DIGIC DV7 image processor that collects the extensive information captured from the DGO sensor and processes it into exceptional HDR imagery while offering choices between Canon Log 2 and 3, in addition to PQ and HLG gamma functionality. The C70 camera can also record 4K DCI or UHD up to 120fps and 2K DCI or HD up to 180 fps – with an important flexibility in the choice of codecs.

The camera supports XF-AVC format (in variable bit-rate) – both Intra and Long GOP with MXF file format. The intra-frame format compresses the data after analyzing each frame separately, while Long GOP format compresses data at a higher rate, creating an even smaller file size. A secondary choice is Long GOP 10-bit 4:2:2/4:2:0 MP4/HEVC (a next-generation HDR video recording compression standard) with an MP4 file format – a first in the Cinema EOS line.

The camera’s independent air intake system is separated from the electrical systems to protect the sensor from water, sand, and dust. In addition, the camera also features two air outlet vents that allow uninterrupted recording for extended periods of time.

Additional features of the Canon EOS C70 4K Digital Cinema Camera include:

  • New Direct Touch Menu System
  • Coordinated Electronic Image Stabilization
  • Two built-in Mini XLR inputs
  • Time-code input/output terminal
  • Custom picture processing via import of 3D LUTs and recording to Look Files
  • Dual-SD card slots
  • Built-in stereo mic
  • Support for optional Canon RC-V100 remote control

Canon Mount Adapter EF-EOS R 0.71x

The Canon Mount Adapter EF-EOS R 0.71x is a new optical adapter that allows users to tap into Canon’s extensive collection of superb full-frame EF lenses when operating the EOS C70 camera. The adapter implements two critically important functions – preserving the similar FF wide angle image onto the 4K Super 35mm image sensor while simultaneously elevating the lens camera sensitivity by one stop. The mount adapter preserves full electronic communication between the lens and camera, enabling optical lens corrections and transfer of lens metadata between the EOS C70 camera and select Canon EF lenses*.

Price & Availability

The Canon EOS C70 4K Digital Cinema Camera is scheduled to be available in November 2020 for an estimated retail price of $5499.00. The Canon Mount Adapter EF-EOS R 0.71x is scheduled to be available in December 2020 for an estimated retail price of $599.99**.
