Sony Alpha a7 III Mirrorless Camera- Body Only
The Sony Alpha a7 III Mirrorless Digital Camera is a well-rounded camera perfect for both photo and video applications. It features a full-frame 24.2MP Exmor R BSI CMOS sensor and BIONZ X image Processer that pair to achieve impressive 10 fps continuous shooting as well as improved autofocus performance for faster, more reliable subject tracking along with wide frame coverage. This sensor structure works with gapless on-chip lens design and an anti-reflection coating, as well as eliminating the optical low-pass filter, to improve light collection and enhance detail. A copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution stills with a sensitivity range from ISO 100-51200, which can be further expanded to ISO 50-204800. UHD 4K video recording is also supported 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.
Fast Hybrid AF System
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 achieves twice the focusing speed, more reliable tracking, and improved low-light focusing compared to previous a7 models. The use of phase-detection points also enables the use of A-mount lenses via the optional LA-EA3 or LA-EA1 lens mount adapters with full continuous AF/AE tracking compatibility.
The focusing system also allows for a variety of focusing functions, including Lock-on AF, for maintaining focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject, and Expanded Flexible Spot, which employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus. Additionally, Eye AF can be used to base focus on recognized subjects' eyes for portraits and is available in both AF-S and AF-C modes. Autofocus can also be used in conjunction with the Focus Magnifier function for critical focus when homing in on minute subject details. The rear touchscreen can also be used for Touch Focus control, and a Touchpad Focus Control mode lets you use the rear screen intuitively while keeping your eye to the viewfinder.
5-Axis SteadyShot INSIDE Image Stabilization
The a7 III also features a 5-stop effective 5-axis SteadyShot INSIDE image stabilization system that compensates for five different types of camera shake in stills and video. This means users can confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake. All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.
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 using 2.4x oversampling renders greater detail and full pixel readout is possible, that is void of pixel binning, for higher quality imagery with reduced moiré and aliasing. Full-frame 4K recording has been improved for improved quality when working at mid to high sensitivities to permit full use of the sensor width. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both 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.
The a7 III allows for extensive customizable color and gamma controls. Users can adjust the gamma, black level, knee, color level, and more. Users can also use the same S-Log2 Gamma Curve that is found on high end Sony Cinema Cameras that squeezes up to 1300% more dynamic range into the video signal then traditional REC709, for increased post-production flexibility. HLG (Hybrid Log-Gamma) support is also available, along with the BT.2020 color space, for recording within a wide color gamut and, in addition to S-Log2, S-Log3 is also available for producing an effective 14-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.
