Description

Well-Rounded Perfection
Distinguished by its updated sensor design, the Sony a7 III is a well-rounded camera suitable for both photo and video applications in a variety of working situations. Refined for improved speed and low-light performance, a new 24.2MP Exmor R BSI CMOS sensor and BIONZ X processor benefit image quality, video capabilities, and AF performance. The a7 III also sports a revised body design, with a new touchscreen LCD, improved EVF, larger battery, and dual memory card slots.

Full-Frame BSI Sensor and BIONZ X Processor
Featuring a back-illuminated design, the full-frame 24.2-megapixel Exmor R CMOS sensor works with the BIONZ X image processor to offer high-resolution stills and video while minimizing noise and improving speed.
The BSI design also dramatically improves data transmission speed for creating 14-bit, high-resolution stills with a native sensitivity range from ISO 100-51200, which can be further expanded to ISO 50-204800.
Also, it enables internal UHD 4K video recording with a wide dynamic range using the full width of the full-frame sensor.
The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times along with the ability to capture an impressive 15-stop dynamic range at low sensitivity values.

The sensor and processor combination also avails fast continuous shooting at up to 10 fps at full resolution, for up to 177 consecutive frames, and with full-time AF/AE when working with either a mechanical shutter or an electronic shutter.
If shooting in live view mode, a continuous shooting rate of up to 8 fps is also possible.

UHD 4K Video Recording in XAVC S Format
Internal recording of UHD 4K movies is possible in multiple frame rates up to 30 fps and uses 2.4x oversampling, which renders greater detail, and full pixel readout is possible, too, for higher quality imagery with reduced moiré and aliasing.
Full HD 1080p recording is also supported in frame rates up to 120 fps, and both 4K and FHD resolutions utilize the 100 Mb/s XAVC S format contained within an MP4 wrapper with 4:2:0 sampling.

The high-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate set to either 30p or 24p.
In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 sampling.

S-Log3, HLG, and Other Color and Gamma Controls
• Extensive customization of gamma, black level, knee, and color settings
• S-Log2 Gamma Curve allows up to 1300% more dynamic range than traditional REC709
• HLG and BT.2020 support for wide color gamut recording
• S-Log3 enables up to 14-stop dynamic range for greater grading control

Autofocus and Image Stabilization

Fast Hybrid AF System
• 693 phase-detection AF points covering approximately 93% of the frame
• 425 contrast-detection areas
• Twice the focusing speed and improved tracking performance

• Lock-on AF for moving subjects
• Expand Flexible Spot to maintain focus
• Eye AF for portrait work (AF-S and AF-C modes)
• Focus Magnifier for precision focusing
• Touch Focus and Touchpad Focus Control

5-Axis SteadyShot INSIDE Image Stabilization
A 5-axis stabilization system provides up to 5 stops of compensation for camera shake.
It corrects:
• Pitch and yaw (telephoto use)
• Horizontal and vertical shift (macro work)
• Roll (general shooting)

Works with native, adapted, and optically stabilized lenses.
