Sony Alpha a7 III Mirrorless Digital Camera (Body Only)

Sony ILCE-7M3 Alpha a7 III Mirrorless Digital Camera Overview

The Sony a7 III (7m3), with an updated sensor, is suitable for photo and video applications in various working situations. Designed for improved speed and low-light performance, thanks to its new 24.2MP Exmor R BSI CMOS sensor and BIONZ X processor for better image quality, video capabilities, and AF performance. The a7 III (7m3) also with 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

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 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.

Additionally, the sensor and processor combination allows for fast continuous shooting at up to 10 frames per second at full resolution, for up to 177 consecutive shots, and for full-time autofocus and autoexposure. A continuous shooting rate of up to 8 frames per second is also achievable when using the live view mode.

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.

Autofocus and Image Stabilization

An evolved 4D FOCUS system now employs a combination of 693 phase-detection points, which cover approximately 93% of the frame, along with 425 contrast-detection areas for reliable and quick autofocus and subject-tracking performance. This Fast Hybrid AF System now achieves twice the focusing speed and more reliable tracking compared to previous a7 models, as well as improved low-light focusing.

Body Design and Connectivity

• The XGA OLED Tru-Finder EVF features a 2.36m-dot resolution and 0.78x magnification for bright, clear viewing in high detail.
• In addition to the EVF, a 3.0" 922k-dot rear LCD is also available, which has a touch panel design for intuitive operation and focusing control. The screen also tilts upward 107° and downward 41° to benefit from high and low angles.
• Magnesium-alloy chassis assures rigidity, durability, and stability while remaining lightweight. The lens mount has also been improved to better support heavy lenses and the grip rigidity has been improved for more comfortable hand-holding.

• Using the NP-FZ100 battery, the a7 III has improved battery life and is now rated for approximately 710 shots per charge.

• A USB 3.0 Type-C port has been added, in addition to a micro-USB port, for faster, more reliable tethering support. The USB Type-C connection allows the camera to be charged from the host power source while connected.

• Built-in Wi-Fi enables the a7 III (7m3) to instantly share imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites.

• Bluetooth connectivity allows for location data acquisition.
