Overview
The updated Fast Hybrid AF System employs a combination of 693 phase-detection points and 425 contrast-detection areas for the quicker acquirement of focus in a variety of lighting conditions, and also maintains focus on subjects more effectively.
In addition to speed and AF, the processing improvements also help to realize greater image clarity and reduced noise throughout the sensitivity range from ISO 100-51200, which can further be expanded to ISO 50-204800.
Video recording capabilities have also been extended for enhanced quality when recording UHD 4K video with the full width of the full-frame sensor to minimize moiré and aliasing.
Additionally, benefitting both stills and video operation, the a7 III utilizes a 5-axis SteadyShot INSIDE sensor-shift image stabilization, which is now effective to minimize the appearance of camera shake by up to 5 stops.
Beyond just updates to the imaging system, the a7 III’s body design has also been revised to include a rear 3.0″ 922k-dot touchscreen LCD, which has a tilting design to better support working from high and low angles.
A 2.36m-dot Tru-Finder OLED EVF is also featured for bright and clear eye-level monitoring.
For greater shooting flexibility, dual SD memory card slots are now featured, and a larger NP-FZ100 battery is also employed to achieve up to approximately 710 shots per charge. Suiting the camera’s use in trying conditions, the magnesium-alloy chassis and weather-sealing also render the a7 III dust- and moisture-resistant.
Gain control of expressive freedom
With outstanding imaging capability and high-speed performance contained in a compact body, the α7 III gives you the power, precision and flexibility to capture once-in-a-lifetime moments just as you like.
Rendering scenes in realistic detail
A newly developed back-illuminated image sensor and evolved image processing system fulfill various shooting needs with high-quality imaging capabilities that you would expect only of a full-frame camera.
4D FOCUS — AF performance evolves
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.
High-resolution 4K HDR
As well as the new capability of recording stunning 4K movies through 2.4-timeshigher oversampling, the camera features a new HLG (Hybrid Log-Gamma) picture profile, supporting instant HDR workflow.
