Utilizing a back-illuminated design, the full-frame 24.2-megapixel Exmor R CMOS sensor collaborates with the BIONZ X image processor to deliver high-resolution photos and videos with reduced noise and enhanced speed. This BSI architecture significantly boosts data transmission speed, facilitating the creation of 14-bit, high-resolution stills within a native ISO range of 100-51200, expandable to ISO 50-204800. The setup also supports internal UHD 4K video recording with wide dynamic range, utilizing the full sensor width.

Additionally, the BIONZ X processor, coupled with a high-speed front-end LSI, enables swift processing and achieves an impressive 15-stop dynamic range at low sensitivities. The sensor and processor combination allows for rapid continuous shooting at up to 10 fps at full resolution, capturing up to 177 consecutive frames with full-time AF/AE when using either a mechanical or electronic shutter. In live view mode, a continuous shooting rate of up to 8 fps is also attainable.

UHD 4K Video Recording in XAVC S Format

The Sony a7 III supports internal recording of UHD 4K movies at multiple frame rates up to 30 fps, utilizing 2.4x oversampling for enhanced detail. Full pixel readout ensures higher quality imagery with reduced moiré and aliasing. Full HD 1080p recording is also available at frame rates up to 120 fps. Both 4K and Full HD resolutions use the 100 Mb/s XAVC S format within an MP4 wrapper, employing 4:2:0 sampling.

Additionally, the camera enables high-speed recording at 120 fps, facilitating 4x and 5x slow-motion movie capture at frame rates of 30p or 24p. Alongside high-resolution internal recording, uncompressed HDMI output supports the use of an optional external recorder for pristine 4K recording with 4:2:2 sampling.

S-Log3, HLG, and Other Color and Gamma Controls

The Sony a7 III offers extensive customizable color and gamma controls, allowing users to adjust parameters such as gamma, black level, knee, and color level. It includes the S-Log2 Gamma Curve, commonly found on high-end Sony Cinema cameras, which expands dynamic range up to 1300% more than traditional REC709, enhancing flexibility in post-production.

Support for HLG (Hybrid Log-Gamma) and the BT.2020 color space enables recording in a wide color gamut. In addition to S-Log2, the camera features S-Log3 for achieving an effective 14-stop dynamic range, providing enhanced grading control from shadow to mid-tone regions of the image.

Autofocus and Image Stabilization

The enhanced 4D FOCUS system of the Sony a7 III utilizes a combination of 693 phase-detection points covering approximately 93% of the frame, along with 425 contrast-detection areas. This Fast Hybrid AF System delivers twice the focusing speed and improved low-light performance compared to previous a7 models, ensuring reliable autofocus and subject tracking.

Key features include:
– Lock-on AF maintains focus on moving subjects using a configurable frame set over the desired subject.
– Expand Flexible Spot uses neighboring focus points to retain focus on moving subjects if the original point loses focus.
– Eye AF prioritizes focus on recognized subjects’ eyes, available in both AF-S and AF-C modes for portraits.
– Focus Magnifier allows precise focusing on small subject details.
– The rear touchscreen supports Touch Focus control, and Touchpad Focus Control mode enables intuitive operation while using the viewfinder.

These features collectively enhance autofocus capabilities, making the Sony a7 III well-suited for capturing fast-moving subjects with precision and ease.

5-Axis SteadyShot INSIDE Image Stabilization

The Sony a7 III features a robust 5-axis SteadyShot INSIDE image stabilization system, providing up to 5 stops of compensation to counteract various types of camera shake encountered during handheld photography and videography. This system enables users to confidently use any lens, including adapted lenses, without worrying about blur caused by camera movement.

Key benefits include:
– Pitch and yaw adjustments are corrected for long focal lengths.
– Horizontal and vertical shift compensation benefits macro and high-magnification photography.
– Roll compensation supports stability across all shooting scenarios.

The stabilization operates across all five axes at all times, even when using third-party lenses, adapters, or lenses equipped with their own optical stabilization. This ensures stable and sharp images regardless of the lens used, enhancing versatility and reliability in challenging shooting conditions.

Body Design and Connectivity

The Sony a7 III boasts an XGA OLED Tru-Finder EVF with a 2.36m-dot resolution and 0.78x magnification, offering bright, detailed viewing. Complementing this is a 3.0″ 922k-dot rear LCD with touch panel functionality for intuitive operation and focus control. The LCD tilts 107° upward and 41° downward, facilitating shooting from high and low angles.

Constructed with a magnesium-alloy chassis, the camera ensures robustness, durability, and stability while remaining lightweight. The lens mount has been reinforced to support heavy lenses, and the grip rigidity has been enhanced for comfortable handling.

Weather-sealing protects against dust and moisture, enabling reliable performance in challenging environmental conditions. The NP-FZ100 battery enhances battery life, providing approximately 710 shots per charge.

Dual SD memory card slots offer flexible file storage and handling, supporting options for separating raw and JPEG files or overflow recording. One slot is compatible with UHS-II memory cards for faster data transfer.

For enhanced connectivity, the camera features a USB 3.0 Type-C port in addition to a micro-USB port, facilitating faster and more reliable tethering. The USB Type-C connection allows for charging directly from the host power source during operation.

Built-in Wi-Fi enables instant sharing of images to mobile devices for direct posting on social media, via email, or to cloud storage services. NFC (Near Field Communication) enables quick, one-touch pairing with compatible devices for remote control and live view display on connected mobile devices.

Bluetooth connectivity supports acquiring location data, enhancing the camera’s capabilities for geotagging and location-based services.

Sony FE 28-70mm f/3.5-5.6 OSS Lens

The Sony FE 28-70mm f/3.5-5.6 OSS Lens is an excellent choice for full-frame E-mount photographers seeking a lightweight, versatile zoom. Its compact, portable design makes it perfect for everyday shooting, offering a wide-angle to portrait-length range that adapts well to various subjects and situations.

Optical Design

The lens design includes one extra-low dispersion glass element to minimize chromatic aberrations and color fringing, resulting in enhanced clarity and color accuracy. Additionally, three aspherical elements are integrated to reduce astigmatism, field curvature, coma, and other types of aberrations for sharper overall image quality.

A rounded seven-blade diaphragm enhances the quality of bokeh, producing smooth and pleasing background blur when using selective focus techniques.

Autofocus, Image Stabilization, and Design

An internal focus mechanism and linear motor enhance the speed and responsiveness of the system, making it easier to handle.

Optical SteadyShot image stabilization reduces the impact of camera shake, ensuring sharper images when shooting handheld with slower shutter speeds. This stabilization system can be combined with compatible sensor-shift image stabilization in cameras for even greater control over camera blur.

The lens features a dust- and moisture-sealed design, allowing for reliable operation in challenging weather conditions. Rubberized control rings improve handling, particularly in colder temperatures.
