The Sony Alpha a7 III Mirrorless Digital Camera 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, the full-frame 24.2MP Exmor R BSI CMOS sensor and BIONZ X image processor pair to realize an impressive 10 fps continuous shooting rate and improved autofocus performance for faster, more reliable subject tracking along with wide frame coverage. This updated Fast Hybrid AF System employs a combination of 693 phase-detection points and 425 contrast-detection areas for quicker acquirement of focus in a variety of lighting conditions, and also maintains focus on subjects more effectively. In addition to speed and AF, the processing improvements also help to realize greater image clarity and reduced noise throughout the sensitivity range from ISO 100-51200, which can further be expanded to ISO 50-204800. Video recording capabilities have also been extended for enhanced quality when recording UHD 4K video with the full width of the full-frame sensor to minimize moiré and aliasing. Additionally, benefitting both stills and video operation, the a7 III utilizes a 5-axis SteadyShot INSIDE sensor-shift image stabilization, which is now effective to minimize the appearance of camera shake by up to 5 stops.
Beyond just updates to the imaging system, the a7 III's body design has also been revised to include a rear 3.0" 922k-dot touchscreen LCD, which has a tilting design to better support working from high and low angles. A 2.36m-dot Tru-Finder OLED EVF is also featured for bright and clear eye-level monitoring. For greater shooting flexibility, dual SD memory card slots are now featured, and a larger NP-FZ100 battery is also employed to achieve up to approximately 710 shots per charge. Suiting the camera's use in trying conditions, the magnesium-alloy chassis and weather-sealing also render the a7 III dust- and moisture-resistant.
A compact and weather-resistant option, the Vario-Tessar T* FE 16-35mm f/4 ZA OSS Lens from Sony will satisfy nearly all the wide-angle needs of full-frame E-mount shooters. It also features a constant f/4 aperture for consistent performance and illumination throughout the zoom range. Ensuring optimal image quality, the lens design incorporates five aspherical elements, including one Advanced Aspherical (AA), three extra-low dispersion elements, and the Zeiss T* anti-reflective coating. This combination delivers images that are free from aberrations and flare.
For smooth operation, the lens uses a linear autofocus motor and an internal focusing design. Also, it is equipped with Optical SteadyShot to dramatically reduce the effects of camera shake on your images. Additionally, it has a seven-blade circular diaphragm for smooth, rounded bokeh.
Based on the Zeiss Tessar optical concept, this lens uses a design with 12 elements in ten groups that helps ensure a smaller overall lens size along with reduced flaring, distortion, and chromatic aberrations.
Covering ultra-wide to wide-angle perspectives, this compact 16-35mm will pair nicely with Sony's full-frame E-mount cameras. It can also be used on APS-C format cameras where it will provide a 24-52.5mm equivalent zoom range.
A constant f/4 maximum aperture offers consistent performance throughout the zoom range and also lends greater control over focus position for shallow depth of field techniques.
Zeiss T* anti-reflective coatings have been applied to each lens surface to help minimize reflections in order to provide greater image clarity, contrast, and color fidelity.
Three extra-low dispersion glass elements are featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality.
Five aspherical elements, including one large-diameter Advanced Aspherical (AA) element, are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
