Why to buy Sony Alpha A7 III Mirrorless Digital Camera (Body Only) :
24.2MP Exmor R BSI CMOS Sensor and BIONZ X Image Processor
ring 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. This sensor structure works with a gapless on-chip lens design and an anti-reflection coating to improve light collection and enhance detail. Also, the copper wiring layer 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.
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 now achieves twice the focusing speed and more reliable tracking compared to previous a7 models, as well as improved low-light focusing.
5-Axis SteadyShot INSIDE Image Stabilization
Packed into the robust a7 III is a 5-stop effective 5-axis SteadyShot INSIDE image stabilization system that compensates for five different types of camera shake encountered during the handheld shooting of stills and video. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake.
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. The full-frame 4K recording has also been dramatically improved for improved quality when working at mid to high sensitivities to permit full use of the entire 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.
Touch AF function
Focusing doesn’t get any more intuitive than this. With Touch Focus you can simply touch the LCD screen to specify the desired focus point. Even subjects near the edges of the frame can be instantly selected without having to reframe or manually shift the focus point. Double-tap any point on the monitor for a magnified view of that area when focusing manually. Touch AF allows smooth focus point changes when shooting movies too.
Eye AF automatically detects and focuses on the subject’s eye. It has been notably improved in the a7 III, even when shooting a moving subject in continuous AF mode. Face detection has also been updated for higher reliability when the subject is looking away from the camera when the face is in partial darkness and other challenging situations.
Obust Magnesium Alloy Body WithDust And Moisture Resistant Design
The a7 III body construction features a lightweight, high-rigidity magnesium alloy for the internal frame as well as the top, front, and rear covers. The grip area has also been reinforced with an integrated magnesium alloy front cover. The number of screws securing the lens mount has been increased to six in order to maximize rigidity and durability even when using heavy telephoto lenses. Sealing is provided throughout the body to minimize dust and moisture ingress, allowing it to function reliably in challenging environments9. All major buttons and dials are provided with seals, while media and jack covers and enclosure edges feature tongue-and-groove joints for double protection. Maximum dust and moisture resistance are maintained at lens, vertical grip, and flash unit joints too, providing excellent system reliability.
