This is how Canon’s Dual Gain Output works on the new EOS C70 4K camera

by 10 Comments

There’s been a bit of misunderstanding over exactly what Canon’s Dual Gain Output (DGO) is on the newly announced Canon EOS C70 4K Super 35mm cine camera. Some have speculated that it might be something akin to dual ISO (given that gain and ISO are often interchangeable in the video world) and, well, sort of, but not quite.

Canon has released a new white paper detailing what Dual Gain Output for their new 4K Super 35mm sensor is and exactly how it works to provide over 16-stops of dynamic range.

Canon has released a 0.71x EF to RF speed booster adapter

Canon has announced a new EF to RF 0.71x speed booster adapter. Like the speed boosters from Metabones and similar items from Viltrox and others, it allows you to use lenses designed for a larger sensor on a camera with a smaller sensor while retaining a wider field of view and, as the name suggests, effectively increasing the light transmission.

The release coincides with the launch of the new Canon EOS C70 cinema camera, but could it add more fuel to the rumours that Canon is planning to ditch the EOS M camera system in favour of APS-C EOS R RF mount cameras?

The Canon EOS C70 is Canon’s first RF mount cinema camera – 4K 120fps (without overheating?)

We knew it wouldn’t be long before Canon finally started switching their cinema cameras over to the RF mount and they’ve finally done it. Today, Canon has announced the new Canon EOS C70 Super 35mm cinema camera. They say it’s in a “mirrorless-style body” although it actually looks a lot more like a big ol’ chunky DSLR than it does a little mirrorless camera.

It’s a pretty hefty little beast that offers Dual Gain Output (DGO) claiming an impressive 16+ stops of high dynamic range. Naturally, as it’s Canon, it features Dual Pixel CMOS AF and can shoot 4K DCI at up to 120fps (without overheating, though?) or a Super 16 2K crop at up to 180fps.
