The Sony a7 III is a well-rounded camera suitable for both photo and video applications in a variety of working situations. Refined for improved speed and low-light performance, a new 24.2MP Exmor R BSI CMOS sensor and BIONZ X processor benefit image quality, video capabilities, and AF performance. The BSI design also 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. Also, it enables internal UHD 4K video recording 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. 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. 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. 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. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake. All shooting styles will get usage out of the roll compensation. 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. 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. Weather sealing has been employed to resist dust and moisture for reliable operation in harsh weather conditions.
The Sony FE 70-200mm f/2.8 GM OSS takes its place as a reliable, go-to telephoto zoom for professionals. A member of the G Master series, this 70-200mm delivers high sharpness alongside smooth, clean bokeh, and the bright f/2.8 constant maximum aperture and optical image stabilization also help to ensure sharp handheld shots in available lighting conditions. A constant f/2.8 maximum aperture offers consistent performance throughout the zoom range and also lends greater control over focus position for shallow depth of field techniques. The rounded 11-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques. Four extra-low dispersion elements and two Super ED elements are featured in the lens design, too, and help to control chromatic aberrations and reduce color fringing for increased clarity and color fidelity. The floating elements system benefits image quality when working at the 3.15' minimum focusing distance with 0.25x magnification. This stabilization system can also be combined with a select camera's sensor-shift type image stabilization for more effective control of camera blur. The front lens element features a fluorine coating to protect against smudges and dust from adhering to the glass surface.
