Description
With Dual Pixel CMOS AF, the EOS R provides several very useful AF features.
Solution
Dual Pixel CMOS AF with 5,655 Manually Selectable AF Points**
 |
High-speed Focusing in 0.05 sec.***
The EOS R camera's highly responsive Dual Pixel CMOS AF system features an incredible 5,655 manually selectable AF points** and can delivers the world's fastest AF focusing speed of 0.05 sec.*** This means fast action can be captured and focus can be maintained with speed, accuracy and ease. Whether taking candid photos in the park or making movies in an event space, the EOS R's fast AF helps ensure speedy, accurate and consistent AF.
Test conditions:
- Focusing brightness: EV 12 (room temperature, ISO 100)
- Shooting mode: M
- Lens in use: RF 24-105mm F4 L IS USM, with a focal distance of 24mm
- Still photo shooting with shutter button operation
- AF method: 1-point AF (with Center AF point)
- AF operation: One-Shot AF
** Available AF points may decrease when shooting with AF cropping or in movie mode, or depending on camera settings or lens attached.
*** Among interchangeable lens digital mirrorless cameras incorporating 35mm full frame equivalent image sensors with phase-difference detection AF on the image plane and contrast detection AF, available in the market as of September 5, 2018 (based on Canon's Research). Calculated based on the resulting AF speed measured according to the CIPA guidelines. (Varies depending on the shooting conditions and the lenses used.) Internal measurement method. |

AF Area Coverage of Approx. 88% x 100%^
The EOS R camera features an expansive focus area of approx. 88% horizontal and 100% vertical^ not only with RF lenses, but also when working with select EF lenses. With older EF lenses, or with Extender types I and II, the EOS R focuses approx. 80% horizontally and 80% vertically. This means fast and impressive focusing even if your subject is way off center.
^ When shooting still photos. Actual coverage varies depending on the lens in use. |

AF Points and AF Area
The EOS R camera features a sophisticated AF system with a maximum of 5,655 manually selectable AF points**, which covers almost the entire image sensing area. The EOS R can also be configured to focus on specific areas, using an extended range of selectable modes that include 1-point AF, Expand AF Area, Zone AF and Large Zone AF in addition to the conventional Face+Tracking AF.

EV -6^^ Low-light Autofocus
Amazing for nighttime photography or in very low light, the EOS R camera's brilliant AF can operate in light as dim as a light rating of EV -6^^ where other AF systems may fail or search. Phenomenal AF is achieved even when using lenses with high F numbers. This ultra-sensitive AF works in concert with the EOS R's EVF to clearly capture subjects even when there's limited light.

f/8 and f/11 Compatible in All AF Areas
The EOS R camera's brilliant AF system doesn't just work with bright lenses. With the EOS R, autofocus will operate over nearly the entire image area even when used with compatible f/8 and f/11 lenses. For example, users can take ultra-telescopic 800mm shots using a compact EF 100–400mm f/4–5.6 IS II lens together with an EF 2x III extender, and AF will function properly over the entire field. When used with a III-type extender, the effective AF range is limited to an area roughly 88% x 100% of the total image frame, or 80% x 80% if combined with a I/II type extender. |

Variety of AF Modes including Eye Detection AF
The EOS R camera's Face+Tracking mode helps enhance reliability for tracking moving subjects. When the camera detects a human face, it uses the subject's eye as the AF point, choosing the eye closest to the camera by default. Photographers can also select which eye to focus on by touching the screen or using the camera's AF point selection button and cross keys.

Touch and Drag AF
Touch and Drag AF makes it fast and easy to select a focus point without taking your eye away from the viewfinder. Using the Touchscreen LCD, it's as simple as pointing to the desired area of focus. The chosen AF point is then displayed in the camera's EVF for quick confirmation. |

Focus Peaking
Among the EOS R camera's manual focus aids, Focus Peaking helps establish the focus area quickly and clearly. With manual focus peaking, the outline of the area in focus is indicated by a colored line. Focus Peaking is usable in conjunction with the EOS R's Focus Guide feature, and can be customized with peaking color and detection level specifications that fit the project at hand.

Dual Pixel Focus Guide
For help when using manual focus while recording videos and shooting still images, the EOS R camera's Dual Pixel Focus Guide not only indicates when subjects are in focus, but also displays where the position of focus is relative to the subject. This function can be combined with Zone AF or Face Detection AF as well. |
