The Canon C70 leaks - and includes a speedbooster

I was always curious if Canon was going to make a speedbooster for the RF mount using EF lenses, and here it is. The promotional text for the C70 has leaked as shown below.  The original site has taken down the page (whoops) as it was released ahead of time.

Canon’s EOS C70 brings the power of the RF Mount to its Cinema EOS System range for the first time.

Canon’s smallest and lightest Professional Cinema camera launches alongside a new EF-EOS R Mount adapter to unleash the full creative potential of Canon’s entire EF-Series and RF-Series lens line-up.

Canon Australia today launches the EOS C70 – a compact, versatile video camera that is the first to combine the powerful image quality of Canon’s Cinema EOS System range with the portability and flexibility of its EOS R line-up. For the first time, filmmakers using a Canon Cinema EOS System camera can enjoy the incredible possibilities of the powerful RF-Series lens range.

The EOS C70’s powerfully compact design – complete with professional interfaces and input/output terminals and ports – makes it perfectly suited for a broad range of uses including documentaries, productions of all sizes, newsgathering, and events such as weddings. High production social media content has also never been easier to capture thanks to the EOS C70’s vertical shooting capability. The EOS C70’s compact size yet expansive features enable filmmakers to shoot handheld or on a drone or gimbal, giving them enhanced creative freedom. What’s more, it offers multiple recording formats to SD cards – including 4K up to 120 fps in 4:2:2 10-bit in XF-AVC (All-I or Long-GOP), and MP4 in HEVC (H.265) or H.264 – providing filmmakers with the ability to meet diverse production requirements.

Also launching today is the Canon Mount Adapter EF-EOS R 0.71x – an EF Lens to RF Mount adapter giving filmmakers the freedom to use the entire EF lens line-up¹ with the EOS C70, optimising compatibility across two of Canon’s most popular lens lines. When paired with the EOS C70, the Mount Adapter EF-EOS R 0.71x employs an optical conversion to capture a Full Frame angle of view of an EF lens even when used with a Super 35mm sensor, as well as an increased light transmission of approximately 1-stop. The adapter enables full communication between three EF lenses and the camera body – EF 16-35mm f/2.8L III USM, EF 24-70mm f/2.8L II USM, and EF 24-105mm f/4L IS II USM- providing continued support for Canon’s extensive range of EF lenses². Auto Focus, peripheral illumination and chromatic aberration correction, and the transfer of lens metadata are also fully supported when using the Mount Adapter EF-EOS R 0.71x³.

Powerfully compact professional cinema capabilities

The EOS C70 bridges the gap between two Canon product portfolios – the Digital Interchangeable Lens camera line-up and the powerful Cinema EOS System cameras – with the short flange back design of Canon’s RF Mount making the compact design of the EOS C70 possible. While the camera is the smallest and lightest in Canon’s Cinema EOS System line-up, it’s packed with features that support a versatile range of professional video requirements. It has 13 assignable buttons, a multi-functional hand grip for ease of operability, professional input/output terminals including HDMI and 2x mini XLR terminals for audio, as well as an independent ventilation system. Furthermore, a new, thinner ND filter system gives up to 10-stops of ND filtration⁴, providing filmmakers with flexibility to control exposure while keeping control over the depth of field and enabling significant bokeh, even when using a high-speed lens.

Powering cinema with the consistent and stable performance of RF

Canon’s RF lens line-up is renowned for its excellent image quality and functionality. The Mount technology is engineered to provide advanced benefits for video use and is ideal for Canon’s Cinema EOS System range. Such capability gives filmmakers using the EOS C70 a comprehensive choice of high- quality lenses from the expanding RF range – including telephoto, zoom, high-quality primes, wide aperture and macro lenses. For optimal image stabilisation, the EOS C70 enables Combination IS which brings together the Optical IS in RF lenses and the Electronic IS in the camera body for outstanding stabilisation performance – even when shooting handheld. The enhanced communication capability between the lens and the camera also unlocks additional features such as the ability to display the object distance on the camera’s LCD monitor.

Impeccable 4K image quality

Taking advantage of its Super 35mm Dual Gain Output (DGO) sensor, seen in the highly acclaimed EOS C300 Mark III, the EOS C70 delivers exceptional image quality with over 16 stops of dynamic range. Much like the EOS C300 Mark III, the EOS C70 produces the same true-to-life, cinematic colours, exceptionally clean low-light image quality and superb HDR acquisition capabilities. Thanks to the DGO sensor, and powerful DIGIC DV 7 processor the EOS C70 is an ideal choice for professionals looking to produce high-quality content in 4K. It also supports slow motion capture with 4K 120p recording – with Dual Pixel CMOS AF support, as well as audio recording. For those who desire higher frame rates, 180p is also available in Super16 mode. Recording to Dual SD cards in Canon’s XF-AVC format with 4K 4:2:2 10-bit, the EOS C70 captures high resolution footage for a wide range of applications, from documentary and journalism to music videos and web-based content.

Enhanced support functions

The EOS C70 boasts a number of ‘firsts’ for the Cinema EOS System range. In addition to supporting Canon’s renowned Dual Pixel AF System, it is also the first Cinema EOS System camera to feature the revolutionary EOS iTR AF X (Intelligent Tracking and Recognition) system seen in the newly-launched

EOS R5. The system uses a face and head detection algorithm that works in conjunction with Face Detection AF to greatly improve the reliability of focusing on and tracking the subject. Likewise, the EOS C70 also introduces Auto ISO to the Cinema EOS System range for the first time.

Canon also breaks new ground with the EOS C70, as the first Cinema EOS System camera with a dedicated vertical shooting mode, designed to support the capture of content for social media and digital signage.

Simple storage and workflows

The EOS C70 features several recording options at resolutions from 4K, UHD, 2K, and Full HD. Designed for content producers who want to streamline their post-production workflows, the Dual SD card slots support high-speed UHS-II media – with a variety of configurations such as double slot, relay and simultaneous recording. For the first time in a Cinema EOS camera, it is now possible to record different formats, resolutions and bit depths on each media card slot, offering a truly flexible workflow.

Also launching today is the CJ20ex5B IASE S, a 2-in-1 UHDxs-class lens with a powerful 20x zoom range and 5mm wide-angle which expands Canon’s range of industry-leading 4K broadcast lenses for 2/3- inch sensor cameras.

¹ Full-function lenses can communicate various information with the EOS C70. The following three lenses are full supported without a firmware update: EF 16-35mm f/2.8L III USM, EF 24-70mm f/2.8L II USM, EF 24-105mm f/4L IS II USM. Lenses other than full-function lenses can also shoot with a brighter f-number with an equivalent angle of view as full frame. We will continue to expand the range of full-function lenses by gradually upgrading the firmware.

² As of September 25, 2020, the following lenses are compatible: the EF16-35mm f/2.8L III USM (released in October 2016), the EF24-70mm f/2.8L II USM (released in September 2012), the EF24-105mm f/4L IS II USM (released in November 2016). Canon plans to gradually expand the list of compatible lenses by providing free- of-charge firmware updates in 2021. EF lenses are still compatible with the camera, but Canon recommends that firmware updates be installed in order to effectively utilise functions which link the camera and lens.

³ Available for full-function lenses which include the EF 16-35mm f/2.8L III USM, EF 24-70mm f/2.8L II USM, EF 24-105mm f/4L IS II USM Lenses. Canon plans to gradually expand the list of compatible lenses by providing free-of-charge firmware updates in 2021.

⁴ The ND filter is designed to fit into the 20mm flange back RF system. Motorised variable ND filter (2/4/6/8*/10* stop).
