Canon R10 Autofocus Settings: A Beginner's Guide

On the Canon EOS R10, start with Servo AF for anything that moves, pick Whole Area AF or a Flexible Zone, set the subject to detect (people, animals or vehicles) and leave subject tracking on, which is the default in Servo AF. When your subject is still, switch to One-Shot AF with 1-point AF, and turn tracking off if you want the AF point to stay exactly where you put it.

What the R10's autofocus system can do

The R10 uses Dual Pixel CMOS AF II, which Digital Camera World points out is the same system used in Canon's EOS R3, R5 and R6. Canon says the R10 inherits the AF subject detection technology of the EOS R3, so it can detect and follow people, animals and vehicles.

PetaPixel counts 651 phase-detection points, and The-Digital-Picture lists up to 4,503 positions for a single AF point when you shoot stills. Digital Camera World reports autofocus down to -4EV, which means the camera can still focus in dim light. PetaPixel adds one caveat: the R10 has the R3's smarts but not necessarily its speed, because it does not have a backside-illuminated stacked sensor.

AF spec	Canon EOS R10
AF system	Dual Pixel CMOS AF II
Phase-detection points	651
1-point AF positions	4,503 for stills, 3,713 for movies
Low-light AF limit	-4EV
Subject detection	People, animals (dogs, cats, birds), vehicles (cars and bikes)
Burst with AF/AE	About 15 fps mechanical, about 23 fps electronic

Because the R10 calculates focus on the imaging sensor rather than on a separate sensor like a DSLR, The-Digital-Picture describes its AF accuracy as excellent and expects it to focus consistently accurately even with third-party lenses.

Step 1: Choose One-Shot AF or Servo AF

The AF operation setting decides whether focus locks once or keeps adjusting. One-Shot AF is for still subjects. Servo AF is for anything that moves.

Digital Camera World's advice is plain: any subject that moves, including people, is better with Servo AF. In Servo AF, subject tracking is enabled by default, and every AF area, from a tiny spot to the whole frame, follows the subject as it moves within the frame.

Use One-Shot AF for landscapes, products on a table, or a posed portrait where nobody is moving. The R10 also has a dedicated AF/MF switch on the front of the body for switching to manual focus without opening a menu.

Step 2: Pick an AF area

The AF area tells the camera where to look for your subject. The-Digital-Picture describes the R10's AF area options as similar to those of the R3.

AF area	What it covers	Good for
Whole Area AF	The entire focusing area, up to 651 zones	Subjects that could appear anywhere in the frame
Flexible Zone AF 1 to 3	Groups of points from 9 to 513 zones, with adjustable size and shape	When you know roughly where the action will be
1-point AF	A single point with an adjustable frame size	Precise placement, or picking one subject out of many
AF point expansion, 4 points	Your point plus the points above, below, left and right	A small subject that is hard to keep under one point
AF point expansion, surrounding	Your point plus all surrounding points	A slightly larger target around your chosen spot

Whole Area AF: let the camera find the subject

Digital Camera World suggests Whole Area AF with Animal priority and Eye Detection, so the camera focuses on and tracks the closest subject automatically. PetaPixel notes the R10 can start tracking from anywhere in the frame. Its reviewer, who had been shooting with an EOS R3, wrote that once a subject entered the frame it was trackable just by starting autofocus, with no time spent repositioning the focus point.

This is the easiest setup when you are new: point the camera, half-press, and let the camera find the subject.

Flexible Zone AF: tell the camera where to start

The R10 has three Flexible Zone AF areas, taken from the R3, and you can change their size and shape. You use the zone to choose the part of the frame where the camera should first look for your subject, and the camera then keeps tracking that subject even outside the original zone.

Zones help when Whole Area AF keeps picking something you do not want, such as a person in the foreground when your subject is behind them.

1-point AF: a subject picker in Servo

With Servo AF and tracking on, a single AF point behaves differently than you might expect, and Digital Camera World notes this is the default way of working. You put the point on, for example, one player in a game, and the camera knows that is the player to focus on and track. Digital Camera World shows the same approach with a motorbike: a single point selects the rider, then Vehicle detection tracks them through the frame.

When you want the point to stay put

With subject tracking enabled, Servo AF takes over AF point selection once the subject is established. If you want focus locked to the point or area you chose, turn tracking off. That is useful when you are focusing on something the camera does not recognize, like a flower or a sign.

Step 3: Set the subject to detect

The R10 offers subject settings for People, Animals, Vehicles and no priority. Canon says animal detection covers dogs, cats and birds, and vehicle detection covers motorsports, including cars and bikes. When they are visible, the camera uses a hierarchical approach and focuses on the eyes, then the head, then the body.

Choose the setting that matches your scene. Digital Camera World gives a clear example: set to Animals with only a person in the shot, the camera focuses on the person, but as soon as a dog walks through the background, it jumps to the dog and ignores the person. The current priority subject appears on the Quick Control screen and can be switched with customized buttons.

Canon itself warns that animal and vehicle detection may not work properly with some subjects, and that other subjects may be detected as animals or vehicles. If the camera keeps locking onto the wrong thing, try no priority, or switch to 1-point AF with tracking off.

With several possible subjects in the frame, PetaPixel's reviewer describes arrows appearing outside the tracking box, letting them switch to the target they wanted. Turn on Eye Detection when you shoot people or animals, since Digital Camera World pairs it with subject priority for automatic tracking.

Step 4: Move focus with the joystick and touchscreen

The R10 has a multi-controller joystick on the back for moving focus points quickly. The-Digital-Picture calls it Canon's responsive 8-way type, though it notes that bigger AF area changes still require pressing or holding a control. Digital Camera World points out that the full-frame EOS RP lacks this joystick and calls that a noticeable loss when moving the AF point around the frame.

You can also use the touchscreen. The R10 brings back Canon's touch and drag AF, which lets you tap or drag your finger on the rear screen to move the focus point. Try dragging with your thumb while your eye is at the viewfinder, so you never have to take the camera down.

An AF-ON button sits on the back next to the joystick, and the M-Fn button gives direct access to five settings you choose, within limits. Button customization is more restricted than on other Canon bodies: PetaPixel notes the R10 lacks the register/recall shooting function found on the EOS R7. Set up the buttons you do have so that the subject to detect is quick to change, since that is the setting you will switch most often.

Step 5: Leave AF Case on Auto at first

AF Case settings control how Servo AF behaves. On the R10 you can adjust tracking sensitivity, acceleration and deceleration tracking, One-Shot AF release priority and AF point auto switching independently. Like the 1D X Mark III and R3, the R10 drops the old Case 5 and 6 and adds Case A (Auto), which tells the camera to analyze the scene and optimize the settings in real time. The-Digital-Picture says the system performs superbly in Auto for most uses.

PetaPixel's first impressions found that tracking consistency was not perfect, and suggested the autofocus characteristics could be refined in the menu. Start on Case A. Change one parameter at a time only if you see a repeated problem, such as focus jumping off your subject when something passes in front of it.

Match Servo AF with the right drive and shutter

Canon rates the R10 at up to about 15 fps with AF/AE using the mechanical or hybrid shutter, and up to about 23 fps with the electronic shutter. Canon notes that only some lenses support the maximum speed for continuous shooting with AF, and its Detailed Guide lists them.

PetaPixel warns that the electronic shutter shows a pronounced rolling shutter effect with fast action, because the sensor is not stacked. For sports, kids and pets, use the mechanical shutter. The R10 also has a pre-shooting function.

The R10 has no in-body image stabilization, so stabilization has to come from the lens. Autofocus can be perfect and a photo still look soft from camera shake, so keep your shutter speed fast when you hand-hold.

Landscape or product	One-Shot AF	1-point AF, tracking off	No priority

Autofocus for video

The R10 keeps phase-detection autofocus in 4K video, while Digital Camera World notes that the EOS RP switches to slower, less decisive contrast-detection AF in 4K. In movie mode, 1-point AF has 3,713 available positions. The same subject-to-detect logic applies: choose the subject that matches what you are filming.

Check what worked after each shoot

Digital Camera World recommends learning the settings in order: AF area, subject to detect and subject tracking first, then AF Case. It also notes that Canon's DPP software shows the AF settings used for each photo. When a shot misses focus, look up which area and subject setting you used, and adjust from there.

If you are still setting up the rest of the camera, the Canon camera menu setup guide covers the menus, and Camera Specs Explained breaks down terms like fps and AF points. The R10 uses a 1.6x crop APS-C sensor, which Canon APS-C vs Full Frame explains in plain terms.
