Canon Announces EOS C70 Cinema Camera and EF-to-RF Speedbooster

Canon Announces EOS C70 Cinema Camera and EF-to-RF Speedbooster

Today, Canon announced the EOS C70 which is the company’s first RF mount cinema camera.

The new Canon EOS C70 is a compact style cinema camera meant to take over the low end price point in the lineup. While it may be less costly than its big brothers such as the C300 Mark III, it still holds its own on the spec sheet. Further, if you want a Canon-made cinema camera with an RF mount (sorry RED Komodo), this is your first and only option.

The camera features a Super 35 sensor with the impressive DGO (Dual Gain Output) as found in the C300 Mark III. It can record up to 4K 120p 10-bit 4:2:2 with no crop, or 2K 180p. One differentiator between this camera and the others in the lineup is that there is no raw recording, but there is still Canon Log 2/3 and HLG available for use.

Autofocus is no slouch as it sports Canon’s Dual Pixel CMOS AF and for the first time in a cinema camera, EOS iTR AF X. This is Canon’s way of saying it has intelligent tracking and recognition, and has been seen in the EOS-1D X Mark III. Something sorely missing from their mirrorless and DSLR cameras for video shooting is the built-in neutral density filters found on the EOS C70. This variable ND has up to 10 stops of light filtration, all by pressing a button.

Dual memory card slots accept SD UHS-II cards and there is no recording time limits in camera. There are dual mini-XLR inputs, a full-sized HDMI output, and an articulating touchscreen monitor but no built-in viewfinder.

Announced alongside the EOS C70 is a new EF-to-RF speedbooster adapter. The Canon Mount Adapter EF-EOS R 0.71x allows EF mount lenses to be attached to the C70’s RF mount, and at the same time widens the field of view to compensate full-frame lenses being used on a Super 35 sensor. As a speedbooster, this also means a one-stop increase in light gathering ability. At the time of its release, this adapter will only work on the EOS C70 and only work with the Canon EF 16-35mm f/2.8L III USM, EF 24-70mm f/2.8L II USM, and Canon EF 24-105mm f/4L IS II USM. In the future, Canon plans to release firmware updates for more compatibility across their line of lenses.

The Canon EOS C70 is now available to preorder for $5,499 and will begin shipping in November 2020. The Canon Mount Adapter EF-EOS R 0.71x is priced at $599 and starts shipping before the end of the year.

I absolutely love the design of this thing.

Like a 1DX and an EOS Cinema camera made a baby. Should be a wonderful run and gun documentary camera for folks who can't shell out for a C300 Mark III - which has the same sensor, I believe. Canon claims 16 stops DR on both, which is a lot more than they claim on the C200 and even the C500 Mark II Full Frame - though manufacturer's DR claims are always a grain of salt thing.

But, same price as the C200 except with the sensor and some of the features from the C300 Mark III. Pretty cool.

The high DR is due to DGO.

Funny that their serious video cameras don't have 8k (a "niche" and "a luxury for high end production" that overheats and is not useable) as he says for but they chose to cram that into the R5 as a marketing ploy. They want everything using RF lens because they make all their money selling expensive lens and they know once people have to buy all new lens, they most likely won't change camera companies. They lie so much it's hard to trust Canon anymore and I can't buy expensive gear I don't trust. I'll always be waiting for the catch.

" They lie so much it's hard to trust Canon anymore" Absolute Proof? I don't mean marketing BS and opinions. Show us Proof.

"Marketing BS" isn't proof? They didn't even talk about the still features for a month after promoting 8k. Where does it mention time limits, overheating, waiting times, etc here on their promotions?

I agree that their R5 marketing was incredibly irresponsible and misleading in many ways.

But as far as the RF mount - sure they want to sell lenses, but this also has an EF-RF speedbooster, which would require the use of EF lenses if you want the speedbooster advantages.

PERSONALLY, I am a big fan of short flange cinema cameras (or, preferably, interchangeable mounts), because then you can adapt a bigger range of lenses. That's one reason almost all the cinema lenses I buy are EF or PL mount, instead of M4/3 or E mount or whatever.

Not to get into the pit of rage that is the R5 marketing. Won't really comment on that.

But to answer why this camera doesn't shoot 8k is due to the super 35 format of its sensor coupled with the small size of the sensor. To shoot 8k in super 35 the sensor would have to be huge and would have skyrocketed the price of this camera and heavily impacted the form factor

This camera has a tiny little sensor in it. It barely has enough resolution to record 4k, 8k simply isn't possible.

The sensor size in the C70 is 26.2 x 13.8 mm @ 9.6mp and the sensor size in the R5 is 36 x 24 mm @ 47mp. The R5 has a bigger, much higher resolution sensor and thus it is capable of recording higher resolution video. (albeit with a few catastrophic flaws)

Side note, the tiny sensor is why an R mount speedbooster can exist here. Speedboosters require a bigger format lens to focus into a smaller format sensor in order to function.

That is the clumsiest looking thing ever. Why not just design it like a (motion) film camera?

I am super excited about this camera. I wanted to get a 1D C for shooting continuous video in DSLR form but ended up with the C100 for the ND filters and audio capabilities. Now they put DPAF, ND Filters, and continuous recording in this interestingly shaped C70 body (looks like the XC10 mixed with a C200 plus the RF mount), which would be a definite step up from using my C100 or my 5DIV for video, especially if this C70 will mount on a gimbal-like my Moza Air 2.

Everyone is saying that they crippled the R5 so you’d have to buy an expensive Canon cinema camera instead if you wanted to shoot video and then you look at the price of the C70 and wonder what expensive camera everyone was talking about.
