Dual Pixel AF has become a Canon standard, here’s how it works

Caption 001

It’s safe to assume that Dual Pixel AF (DPAF) has now become Canon’s standard on-sensor auto-focusing technology. Since it made it into a Rebel, it will be featured on almost any future Canon DSLR and MILC (and who knows…maybe also in some high-end PowerShots).

Dual Pixel AF debuted in July 2013 (press release), on the still noteworthy Canon EOS 70D. It took Canon a long time to feature it on other cameras, and even longer to put it into a mirrorless camera. The EOS M5 and EOS M6 are the first Canon MILCs to feature it. And hell if it makes a difference on a mirrorless system. If only Canon had used it before on their mirrorless offering.

However, fast forward to 2017. Dual Pixel AF is now on board with the EOS 800D/Rebel T7i, EOS M6 and EOS 77D. That means  Dual Pixel AF is now featured on a Canon Rebel and everywhere up to the EOS C300 and EOS 5D Mark IV.

The DPAF technology is nothing cryptical or near to rocket science, at least not the fundamentals of the technology.

A good starting point for those who prefer to read is this article by Canon Professional Network.

Dual Pixel CMOS AF is a sensor-based, phase detection Auto Focus (AF) technology designed to provide smooth, high-performance focus tracking in movies and fast autofocus acquisition when shooting still photos in Live View mode.

It is a unique, Canon-developed technology, ideal for creating professional-looking pull-focus effects and keeping a subject moving towards the user in sharp focus while maintaining a blurred background – a defining characteristic of EOS Movies.

Thanks to this groundbreaking advance, capturing a subject and retaining sharp focus, even when moving, has never been easier.

Next, hear what the Canon engineers who developed Dual Pixel AF have to say about the technology (click here).

If you prefer to learn stuff by watching videos, then the two new Canon videos below may suit you, and the other, older, videos about DPAF hopefully too.

    5D Mark VI? I must have been in a coma… did the 5DV get manageable video files? ;)

      no it’s me being in a perennial coma ;-)
      thanks…

  • Good move from Canon to focus on the Dual-Pixel system.

    It´s quite unique on the market (and one of the few points to choose Canon for video beside the colours). Only alternatives are the Sony A6500 or A7r II for now (which are quite similar in performance). I only wished they included it already earlier in their EOS-M bodies (the M3 for example) – Or brought out the M6 instead of the M5 earlier (the M5 was just too expensive at the beginning – Especially here in Europe).

    Dual Pixel AF has made a world of difference when shooting in Live View. It is a major improvement that has equalized performance of Canon DSLR and mirrorless cameras.
