CANON EOS C70 | USER REVI EW
isn’t the new Dual Pixel CMOS AF II technology found in the EOS R5 – that covers pretty much 100% of the screen. Despite this, the AF is among the best fitted to any video camera. It’s adjustable in terms of speed as well as response, and boasts the advanced face detection that works really well. The touchscreen has a touch-to-focus feature, allowing amazing focus pulls with ease. There is no touch-to-track, though, unlike rival cameras. In addition, face detection doesn’t work in the S&Q modes – something we discovered to our cost on a shoot. It’s still right up there as the best AF system for video, and its technology means the Focus Guide system works incredibly well in manual focus. This gives a clear indication of the correct way to turn the focus ring, as well as a
visual signal when the subject is in sharp focus. For example, the RF lenses can be tweaked by using camera settings to change focusing direction. It’s another benefit of the advanced electronics housed inside these newer optics. Many of the lenses include image stabilisation – that’s a positive, since there is no built-in five-axis image stabilisation on the sensor. Instead, the EOS C70 has Combination IS, using the

lower settings, in terms of bit rate and resolution, quality can drop, but even HD is impressive. There are no complaints over image quality, with rolling shutter well controlled, too. Things only start to fall apart slightly when using rolling shutter effects to create high-speed whip pans, or when the ISO creeps up. Nonetheless, low light is where cameras with full-frame sensors really come into their own. At high ISO settings up to 12,800, used professionally, noise appears in shadows, but can be reduced in post. Meanwhile, a Super 35 sensor means the angle of view is different to a full-frame camera using the same focal length lens. To get a shallow depth-of-field, you need a faster lens, meaning high-quality AF is critical. Canon has that covered – the C70 is the first Cinema EOS camera to use the EOS iTR AF X Intelligent Tracking and Recognition autofocus system, seen on the EOS-1D X Mark III. This employs a face and head detection, deep learning technology, working in conjunction with Face Detection AF. It improves focusing reliability and subject tracking. This all sounds great, but AF only covers 80% of the screen and
