AF performance is improved using the same AF advancements as in the α9 and applying it optimally, so once the α7 III captures such unpredictably moving subjects as dancers, boxers, and wild animals in action, it won’t easily let them go.
4D FOCUS: Stunning wide coverage
693. Remarkable number of phase-detection AF points
This camera features 693 phase-detection AF points0 covering approx. 93% of image area plus 425 densely positioned contrast-detection AF points1 to improve focus.
4D FOCUS: Fast AF speed
Up to two times0 faster AF performance
Combining focal-plane phase-detection AF for excellent speed and tracking plus high-precision contrast-detection AF, Sony’s sophisticated Fast Hybrid AF can capture fast-moving subjects in razor-sharp images. This system advances performance to double AF speed0.
4D FOCUS: Steadfast tracking
Enhanced AF tracking for swiftly moving subjects
The AF performance inherited from the α9 accounts for AF tracking with enhanced precision for continuous shooting of quick action. With faster image sensor readout, even complex subject motion can be tracked and sudden movements can be predicted with great precision, allowing you to capture decisive moments.

Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-30, for more reliable autofocus in dark scenes.
Focal-plane phase-detection AF supports A-mount lenses0
693-point focal-plane phase-detection AF not only covers a wide area and responds instantly — it offers the benefits of high tracking performance even with an A-mount lens mounted via mount adaptor LA-EA3.0
Catch the eyes to see into the soul
Eye AF revolutionises portraiture
With the α7 III, Eye AF can now be used with AF-C mode, for fast, effective eye detection/tracking performance when shooting stills. The easy maintenance of optimum focus on moving subjects can totally transform your portraiture.
The α7 III has Touch Focus function, and a Touch Pad function for you to fingertip-drag the focus frame intuitively while using the viewfinder.
AF in Focus Magnifier
Use autofocus for stills while focus area is magnified in viewfinder/monitor, and magnify view after autofocusing. This is ideal for focusing on a small area and other precision-focus photography.
More versatile AF settings all around
AF tracking sensitivity for stills is adjustable in five steps. AF areas/points are changeable as you switch between horizontal and vertical orientation. Focus point settings can be assigned to custom buttons.
