Master your camera: Controlling autofocus on the Catechism EOS 5D Marking Iii

June 4, 2015

More than ever before, photographers are relying on their camera’s AF arrangement to ensure that every shot is perfectly in-focus and pin sharp, even in the trickiest of situations – long gone are the film days where having to manually focus each shot by eye was the norm. With consumer expectations running at an all-time loftier, it’s not hard to understand why over the by few years huge investments have been made past leading camera manufacturers to improve the AF operation within their digital cameras.

Ane example that stands out in particular is the AF system constitute within Canon’s 5D Mark Three and flagship 1D X. With a truckload of highly advanced features and customisable options, this system is arguably the most sophisticated AF system institute within the company’southward current EOS line-up. To start, it features a whopping 61 AF points (41 of which are the more accurate cantankerous-type points, with five dual cross-type) that cover over 50% of the frame, meaning that you’re unlikely to not be able to discover an AF point right where you need information technology.

Although the 5D Mark III and 1D X may be out of the toll range for some amateur photographers, the good news is that we’re slowly starting to see some of this advanced technology trickle down into the lower tiers of Canon’s DSLR range – one example being the 7D Marking II, which incorporates many of the 5D’s sophisticated AF features.

One of the biggest challenges for your camera’south AF is trying to focus on a moving target. Luckily, the AF system within the 5D Mark 3 includes a set of six AF Case sensitivity settings, which have been purposefully designed to enable the AF to perform at its best in a host of different circumstances. Over the next few pages, we’re going to delve deep into the advanced AF settings of the 5D Mark 3 to let you to get the absolute nearly out of your photographic camera’southward focusing organization for sharper shots every time.

Erratic subjects

Sports and wildlife photography are arguably some of the most challenging types of photography to try your hand at, but the results are ofttimes incredibly rewarding. With fast-moving subjects, non only are yous required to think and human action fast in social club to capture the shot, your photographic camera has to work fast, too. If your camera can’t lock on the target quickly and efficiently, information technology can often result in missed photo opportunities. This can exist especially challenging when shooting subjects that are moving erratically and at speed, as the camera may struggle to predict and react to irregular movements every bit chop-chop equally the human encephalon can.

Luckily, the AF system inside the 5D Mark III has been well prepared for a variety of focusing situations with its listing of Example settings. If you’re unfamiliar with these options, just press the Menu button and head over to the first set of options under the AF tab – this volition reveal the half dozen available Instance sensitivity settings. Each of these options have been pre-programmed to alter the style in which your AF will track a target within the frame when the AF manner is set to AI Servo. Each selection is suited towards a particular type of subject movement, so it’s of import to ensure that you select the suitable Case setting before each shoot – this volition dramatically increment your chances of capturing pivot-precipitous shots.


Fast-moving subjects require yous to call back carefully almost what focus settings are best. For this action shot, Zone AF was used with the autofocus configuration fix to the Case iii choice

AF Case Settings

Starting at the top of the list of the six pre-programmed Instance sensitivity settings, we have the ‘Versatile multi-purpose setting’. This option is widely regarded equally the standard setting and is best for tracking subjects with consistent and predictable movements – i.e. a motorcar driving in a straight line. By default, your photographic camera will be set to this pick.

Moving down the list, nosotros adjacent take ‘Go on to track subjects, ignoring possible obstacles’. As its championship suggests, this selection sets the camera so that it will continue to track the subject even if information technology briefly moves off the active AF signal, or another object briefly passes in between the photographic camera and the discipline. This selection tin pay dividends when shooting in a crowded area where other bystanders are likely to briefly arrive the way of your shot while tracking a subject.

Third on the list is ‘Instantly focus on subjects of a sudden inbound AF points’. With this setting active, when a new discipline enters the active AF point area, the camera’s AF system will immediately lock on focus to that subject. This setting is well-nigh useful when you know a subject area is about to come into the frame (i.e. waiting for a car to come up around a bend in the road) and you want the focus to lock on as soon as it becomes visible.

Case number 4 is ‘For subjects that accelerate or decelerate chop-chop’. This pick adjusts the camera’due south AF system and then that information technology can react much more quickly to subjects that deadening downward, cease and even change direction ofttimes – such equally a rugby thespian weaving effectually other players on the pitch. This is the opposite of Case 1.

Next on the list is the pick designed ‘For erratic subjects moving apace in any direction’. If yous’re using more one AF point, activating Example five will permit the camera to switch from betoken to point much faster, which is ideal when tracking erratic side-to-side movement, such as a wild creature running. This is particularly effective when combined with the Auto Selection AF point mode, as this way grants the photographic camera access to all 61 AF points across the frame, making information technology easier for the camera to rails the bailiwick.

Finally, there’south Instance six, which is designed ‘For subjects that change speed and movement erratically’. Merely like Case five, this style also increases the speed in which the camera can alternate between AF points, only in addition information technology also allows the AF to react more than quickly to a subject’s modify in speed, just like that of Case four. This is best reserved for fast-moving subjects that frequently change speed and direction, such as a bird of casualty swooping through the sky.

In one case you’ve become accustomed to each of the Example settings and how they affect the AF organisation of your camera, it’south also possible to further fine-tune these pre-sets to arrange your own requirements. Simply hover over the Case setting that you wish to adjust and printing the RATE button, located to the left of the rear screen. This will accept you into the Instance setting and will permit you to alter each of the three sliders that affect the Case setting’s beliefs – Tracking Sensitivity, Acceleration/Deceleration Tracking, and AF Point Auto Switching.


Starting at the top of the list, the Tracking Sensitivity slider affects the way the AF responds when the subject moves away from the active AF point. Moving the slider to the correct towards ‘Responsive’ will cause the camera to react and re-focus faster when in that location are changes in what your AF can ‘run into’. Moving the slider left to ‘Locked on’ will tell the camera to resist making changes and continue to track the original field of study.

Acceleration/Deceleration Tracking allows y’all to suit how the AF responds to moving subjects. At that place are iii notches on the slider; 0 adjusts the tracking for continuously moving subjects, whilst +1 and +2 incrementally increase the AF’due south sensitivity to subjects that change speeds or terminate moving entirely.

Finally, there’s AF Indicate Auto Switching. Whenever you are working with more than i active AF bespeak, this setting will determine how quickly the autofocus will shift between points in order to proceed tracking the subject. When set to 0, the AF will provide gradual AF point switching, while the +ane and +2 settings will cause the AF point to motion more quickly as the photographic camera detects subtle subject movements.

By adjusting each of these sliders to your own personal preference, the Canon 5D Mark III enables you to have incredible control over the AF arrangement, assuasive you to capture sharp shots every time.

Photographic camera orientation


AF menu

Did y’all know that you lot can set up unlike agile AF points when shooting in portrait and landscape? Simply printing the Menu button and navigate to the fourth set of options in the AF menu. Highlight over the ‘Orientation Linked AF Bespeak’ option and press the Ready button, then choose ‘Select Dissever AF Points’ and press the Menu button to back out. Now, while holding the camera in landscape, printing the AF Point Pick push button and ready the active AF point to your desired location – one-half depress the shutter push button to back out. Tilt the photographic camera to portrait and printing the AF Point Option push button again, then set the active AF point to a different location within the frame. While looking through the viewfinder, you’ll now notice that as you rotate the photographic camera between portrait and landscape that the active AF point volition automatically adjust according to positions y’all determined. This can be extremely useful if you oft switch between orientations.

Setting up the AF on  your Canon 5D Mk III

If yous own a Catechism EOS 5D Mark Three y’all have a vast number of autofocus settings at your disposal. If you’ve never explored these before, information technology’due south about time you exercise, so y’all’ll know how to set up the camera up quickly for every eventuality.


Step 1

Adjust the AF mode Start by pressing the AF Drive button, then use the master command bike and curl to the AF Servo selection. With the AF Servo mode selected, the photographic camera’s AF will continually suit the focus so long equally the shutter push button is half depressed, which is amend suited to moving subjects.


Step two

Gear up the Drive mode While still in the AF Drive options, utilise the camera’s secondary command wheel to set the Bulldoze way to High Speed Continuous. This’ll allow yous to shoot in rapid succession, which is e’er best for quickly moving subjects, as information technology’ll dramatically increase your chances of capturing a suitable shot.


Step 3

Select Zone AF Press the AF Point Choice push button and and then repeatedly printing the M-Fn button (just in a higher place the shutter push button) to cycle through the choices – select the Auto Choice: 61 points way. This manner will allow the AF to freely use all of the AF points to retain focus on the subject area.


Footstep iv

Adjust the Case sensitivity Press the Card button and navigate to the beginning set of options in the AF carte du jour to see the Instance sensitivity settings. Wait through the list and carefully decide which Instance setting will exist best suited to your subject’s movements. Selecting the correct mode will increase the operation of your AF.


Step 5

Shoot and review Raise the photographic camera to your heart and await for the subject to pass in to the frame and over your AF points. Immediately half-depress the shutter button until the AF locks on, and so fully-depress and concur the shutter to rattle off a stream of shots. Review the shots and repeat.
