Sony a7 V Autofocus Settings: Modes, Areas and Tracking

For most shooting on the Sony a7 V, set the focus mode to AF-C, choose a tracking focus area, and leave subject recognition on Auto, switching to a specific subject type only when the camera locks onto the wrong thing. That setup lets the camera follow subjects across the frame and recognize people, animals, birds, insects, cars, trains and airplanes on its own.

What changed in the a7 V autofocus system

The a7 V uses a new BIONZ XR2 processor with the AI processing unit built into it, where earlier Sony bodies used a separate AI chip. PetaPixel describes this single-unit design as a first for Sony Alpha cameras and says the integrated AI also helps with white balance and exposure, not only focus. TechRadar frames it as all AF computations moving on-chip instead of being split between two units.

Sony claims up to a 30% improvement in Real-time Recognition AF over the previous model. The sensor has 759 PDAF points, which Sony says cover up to 94% of the frame and work down to EV -4.0. TechRadar's review lists that coverage as 90%. Photography Blog adds that the phase-detect points are supported by 425 contrast-detect points. If the spec terms are new to you, the camera specs explainer covers them.

Focus modes: AF-C or single-shot

The focus mode decides when the camera focuses. AF-C continuously adjusts focus, which is what you want for anything that moves. In Single Shot mode, autofocus activates only when you half-press the shutter or press AF-ON, and focus stays where it landed.

Use single-shot focus for still subjects: a landscape, a product on a table, a posed portrait where nobody moves. Use AF-C for kids, pets, sports, wildlife, street scenes and any video. If you are unsure, AF-C is the safer default, because a still subject stays sharp in AF-C too, while a moving subject drifts out of focus in single-shot mode.

Back-button focus with AF-ON

The AF-ON button on the back activates autofocus separately from the shutter button, a technique called back-button autofocus. The appeal is control: you hold AF-ON to track, let go to freeze focus, and the shutter button only takes the picture. Try it for a week before deciding. If you want the shutter half-press to stop starting focus, that is a menu change. The a7 V carries over the dials, controls and custom buttons from the a7 IV, so the a7 IV custom button guide is a useful map of the layout.

Focus hold buttons on lenses

Some lenses have a focus hold button on the barrel, which by default locks the current focus position so the camera does not hunt for a new subject. That button can be reprogrammed through the menu, like the custom buttons on the body. It is handy when you have focus where you want it and are waiting for the moment.

Focus areas: where the camera looks

The focus area decides which part of the frame the camera uses. Tracking modes let the a7 V follow a subject as it moves across the frame. Sony describes Real-time Tracking as AI-based recognition that uses color, pattern and subject distance information.

A practical approach: start in a tracking area, place the point on your subject, and start focus. The camera then holds that subject wherever it goes. For still work where you want one exact spot sharp, a small fixed point gives you more control than letting the camera choose.

New point sizes and AF responsiveness

The a7 V adds an extra small and a large AF point size, plus a setting to change AF responsiveness. TechRadar suggests turning AF responsiveness down when other objects are likely to pass between you and your subject, such as shooting across a busy road or players on a football field, so focus stays on your subject. The extra small point suits precise placement, like a single eye through foliage, while the large point is more forgiving with erratic subjects.

Leave responsiveness at its default until you see a problem. If focus keeps jumping to things that cross the frame, lower it. If focus is slow to switch when you deliberately move to a new subject, raise it.

Touch focus and touch tracking

Touch Focus and Touch Tracking are both on the a7 V's feature list. Digital Camera World's reviewer describes tapping the subject on the touch screen to make tracking lock on. TechRadar's reviewer noted that a single tap activates AF and snaps to the selected object. The screen is a 4-axis multi-angle design that combines tilt and vari-angle movement, which makes tapping easier at low or high angles. If you keep changing settings by brushing the screen with your nose or hand, press C4 to temporarily disable touch operation.

Subject recognition: what the camera can find

Subject recognition tells the camera what kind of subject to look for inside the focus area. On the a7 V, Real-time Recognition AF supports these types:

Mode	What the evidence says
Human	Eyes and faces, plus torsos and limbs for sports and action
Animal	Eyes, heads and bodies of dogs, cats and similar animals, plus the eyes of some grazing and small animals; about 30% improved
Bird	About 50% improved recognition
Insect	Supported
Car/Train	Supported
Airplane	Supported
Auto	Detects the subject type automatically

Auto mode or a specific subject

Auto means you no longer have to pick the subject type before you shoot. Fstoppers summarizes Jacek Sopotnicki's long-term review as noting that on the a7 IV you had to pre-select the subject type, and by the time you did, the moment was often gone. You can still choose a specific type, for example to focus on a pet and not its owner, or a driver and not the car.

PetaPixel's reviewer found better consistency when forcing an appropriate mode than when letting the camera switch automatically. A sensible rule: run Auto for everyday and mixed scenes, and switch to a specific mode when you know your subject in advance, like Bird for a day at the lake or Human for a wedding.

Changing the mode quickly

The Fn button opens a quick-access overlay that includes subject recognition mode, so you can switch between person, animal, bird and the rest without digging into the main menu. Learn that path early, because switching modes is the fix you will reach for most often.

Real-time Eye AF

Real-time Eye AF refines focus on the recognized eyes and faces of subjects. Sony says it recognizes human, animal and bird eyes and keeps focus on an eye when the subject leaves and re-enters the frame. For portraits, this means you can spend your attention on expression and composition rather than on moving a focus point onto the nearest eye.

Tracking moving subjects

The partially stacked sensor allows 30fps blackout-free shooting with autofocus and auto exposure, and Digital Camera World reports a buffer of up to 185 JPEG or 85 RAW images with CFexpress Type A cards. Pre-capture can be set from 0.03 to 1 second before you press the shutter, which gives you a safety net for moments that start before you react.

The EVF can switch between 60 and 120 fps, with 120 fps giving smoother subject tracking and 60 fps saving power. For action, set it to 120 fps.

In PetaPixel's testing, the a7 V kept focus on human subjects even with trees and obstacles passing between the camera and the subject. TechRadar found that focus slowed and hunting increased as light dropped, though the camera still found and tracked the subject. In dim rooms, give the camera some contrast to work with and expect a little more hesitation.

Lens choice matters for fast action. Sony says the FE 28-70mm f/3.5-5.6 OSS II offers up to 120 fps AF/AE tracking with compatible cameras and keeps AF working during zooming.

Autofocus for video

PetaPixel describes video autofocus as a huge improvement over the a7 IV and says you rarely need to tweak AF settings: start tracking on your subject and the camera keeps them in focus. For manual focus or checking focus, the a7 V lists Focus Map (Movie), Peaking Display and Focus Magnifier among its features. Peaking is the quickest way to confirm what is sharp on a small screen.

A starting autofocus setup

Use this as a baseline, then adjust for what you shoot:

• Focus mode: AF-C for anything that moves and for video; single-shot for still subjects.
• Focus area: a tracking area for people, pets and action; a small fixed point for precise still work.
• Subject recognition: Auto for general shooting; a specific type when you know the subject or Auto picks the wrong one.
• Eye AF: on, for any portrait or animal work.
• AF responsiveness: default, lowered when things keep crossing in front of your subject.
• EVF: 120 fps for action, 60 fps to save battery.
• Fn menu: keep subject recognition in it so you can switch in a second or two.

Practice on a moving subject at home, a pet or a family member walking across a room, before an event that matters. Watch where the focus box goes and change one setting at a time so you know what each one does.

Coming from the a7 IV

If you are upgrading, the body will feel familiar: PetaPixel notes the chassis is almost identical and the dials, controls and custom buttons carry over from the a7 IV. The biggest autofocus difference in daily use is the Auto subject mode, since the a7 IV made you pre-select a subject type. The a7 IV's top continuous rate is 10 frames per second, against 30fps on the a7 V.

The a7 IV remains a capable camera, and many of the habits in this guide, AF-C for motion, tracking areas and Eye AF, apply to it as well. Its blurry photo fixes guide covers focus problems that also happen on newer Sony bodies.
