The Canon EOS C70 packs professional video quality into a portable frame while flexing features any videographer would find useful. From the nuts and bolts to the key details, this review will cover everything you need to know before buying the C70 for yourself.

Ergonomics & Handling

Right off the bat, the C70 shines in this area compared to other cine cameras. Its ergonomics are so stellar that you’ll have no issue taking it for long shoots. The compact form factor bridges the gap between traditional cine cameras and smaller mirrorless bodies so you get the best of both worlds. Its grip is solid and well-contoured so you have a secure hold even when shooting handheld. 

The control layout features easily accessible buttons and dials that simplify setting adjustments. Although it may be missing a built-in viewfinder, the side-mounted LCD screen is handy for monitoring and framing shots without adding bulk. Overall, the C70 feels like it’s built for filmmakers who need a versatile, user-friendly tool that doesn’t sacrifice performance for portability.

Performance Analysis

Effective autofocus may be rare in video cameras, but the C70’s autofocus consistently comes up clutch. Thanks to Canon's Dual Pixel CMOS AF, the camera locks onto subjects quickly and smoothly, covering about 80% of the frame. Whether you're filming fast-paced action or a simple interview, the C70's Face Detection and Tracking features keep your subjects sharp and in focus even when they're moving around. Plus, with EOS iTR AF X using deep learning, the camera gets even better at recognising and following your subjects.

The battery life also stands out as a positive, as both options provide plenty of juice. The C70 uses BP-A30 and BP-A60 batteries, giving you 200 minutes or 400 minutes of recording time, respectively. The camera comes with a BP-A30 battery while upgrading to a used BP-A60 costs around £110 from MPB.

The C70 could be better when it comes to low-light capabilities. You won’t be terribly disappointed, but you won’t want to shoot in dark conditions without flashguns, either.

Custom Picture Settings & Log Formats

While shooting at the Jersey Shore, we shot most of our tests in C Log 2. This gave us the best dynamic range for colour grading in post.

You can also use C Log 3, BT.709, PQ and HLG. These options run the gambit depending on your post-production colour grading process. You can also import your own custom LUTs.

There are also several options when choosing your media formats and resolution. You can select RAW ST, which gives you a higher bit rate and heavier but higher-quality footage, or RAW LT, which has a lower bit rate but gives you 60 fps capabilities. It’s important to note that these differ from Cinema Raw Light, which has even less compression.

If you skip shooting in RAW for an easy post-process experience, you can shoot in XF-AVC format in 422 10-bit. You’ll have two file compression options: intra-frame and long GOP. Intra-frame goes frame by frame for higher quality at a higher bit rate, while long GOP compresses multiple frames for a lower bit rate at 60 fps (vs. 30 for intra-frame).

Audio

The C70 caters to professional videographers with fantastic audio features. It includes two mini XLR inputs with phantom power support that allow for high-quality, balanced audio recording with professional microphones. The camera supports 24-bit/48 kHz linear PCM audio, ensuring superior sound fidelity. The C70 also offers manual audio level control and real-time audio monitoring through a dedicated headphone jack, giving you precise control over audio capture in any filming condition.

Monitoring Features

The Canon C70 really shines when it comes to monitoring your shots, offering a mix of convenience and flexibility. Its built-in 3.5-inch LCD screen is not just crisp and clear with 2.76 million dots of resolution, but it’s also a touchscreen, making it super easy to tweak settings and navigate menus on the fly. This is great for quick adjustments when you’re on the move. 

If you need something more, like a bigger screen for client reviews or multi-camera work, the C70 has you covered with its full-size HDMI port, which supports 4K output to an external monitor. So whether you’re relying on the onboard display or hooking up to a larger external one, the C70 ensures you always see your footage exactly how you want to.

Canon C70 vs. Sony FX3

Another top-notch mid-range cine camera is the Sony FX3. While the C70 offers exceptional dynamic range and Canon's renowned color science, the FX3 excels in low-light conditions with its impressive ISO range. 

The FX3 features a compact body, excellent autofocus and seamless integration into the Sony ecosystem, including the ability to shoot up to 4K at 120fps. Its focus on handheld shooting and gimbal use makes it perfect for action-packed scenes. 

Ultimately, the choice between these two depends on whether you prioritise Canon's colour science and built-in features or Sony's full-frame look and low-light prowess.

Final Thoughts

It’s not the flashiest cine camera out there, but the Canon C70 accomplishes most things. If you can look past the run-of-the-mill low-light capabilities and the lack of features that only high-end options flex, the C70 could be the perfect camera to help you make a cinematic masterpiece.
