Sony a7S III has one of the best 4K video features in a full-frame mirrorless camera, including 120fps capture for slow-motion playback. There are handsome reasons to upgrade if you’re still using an a7S II. Video-first creators using the Sony full-frame camera system enjoy the a7S series for its native 4K sensor, exceptional low-light performance, and compact form factor. Hybrid creators with a video-first mentality will be pleased with the camera’s versatility. You can get the 3rd-generation a7S III at $3,499.99 (body only) with upgraded autofocus performance for both still and video, decrease rolling shutter, and supports 120fps capture at 4K. The a7S III is the same general size and shape as most other full-frame mirrorless cameras. It measures 3.8 by 5.1 by 2.7 inches (HWD) and weighs about 1.4 pounds without a lens.
A7S III is available in basic black with magnesium alloy construction and internal seals to withstand dust and splashes. An integrated handgrip and an eye-level viewfinder are included. The rear LCD of the a7S III swings out to the side and faces forward, where other a7 cameras only offer upward and downward tilt. The a7S III has a mechanical shutter and EVF including active cooling for long-form recording. Its handgrip is similar to the a7R IV and a9 II. This model has a comfortable body to use with big telephoto lenses, but still light enough to use with a wrist strap. The camera includes record and C2 buttons sit behind it on the top plate, along with lockable dials to set the shooting mode and EV compensation. The a7S III supports JPG, HEIF, and Raw imaging, and uses an upgraded Sony NP-FZ100 battery.
The touch LCD is a 1,440k-dot panel with adjustable brightness. Point to be noted that Panasonic’s camera uses a different lens system, L-mount, but supports 6K capture and includes a 2,330k-dot display. The a7S III sports a full array of accessory ports. Both USB-C and micro USB are included and serve a variety of purposes including file transfer, charging, webcam, and tethered control. A full-size HDMI port is there for use with external monitors and recorders. The camera has a built-in 3.5mm microphone, 3.5mm headphone connection ports, and support external audio. The a7S III works with Sony Imaging Edge Mobile and features Bluetooth, NFC, and Wi-Fi for wireless transfer and remote control. The Real-Time Tracking function in the autofocus system isn’t brand new, but this is the first a7S model to include it.
