The Alpha a7 III Mirrorless Digital Camera from Sony 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. 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. 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. 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. Also, it enables internal UHD 4K video recording with a wide dynamic range using the full width of the full-frame sensor. 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. 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. 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 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. This viewfinder design also affords the use of autofocus in the Focus Magnifier mode as well as improved focusing peaking to benefit manual focus operation. the FE 24-105mm f/4 G OSS Lens from Sony is a wide-angle to short-telephoto zoom designed for E-mount mirrorless cameras. Complementing the useful range of focal lengths is a constant f/4 maximum aperture, which maintains consistent performance throughout the zoom range and also affords increased control over depth of field. Benefitting the reach is an advanced optical design, which employs aspherical and extra-low dispersion glass elements to control color fringing, distortion, and a variety of aberrations for greater sharpness and clarity. this 24-105mm f/4 also incorporates an Optical SteadyShot image stabilization system to minimize the appearance of camera shake for sharper handheld shooting, and this system can pair with select cameras' sensor-shift image stabilization for even more effective blur control. Suiting both stills and video shooting, a Direct Drive Super Sonic wave AF motor, along with an internal focusing design, provides quick and quiet focusing performance as well as natural manual focus control. 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. Three extra-low dispersion elements are also used to minimize color fringing and chromatic aberrations for greater color accuracy. Optical SteadyShot image stabilization helps to minimize the appearance of camera shake for sharper imagery when shooting handheld with slower shutter speeds. This stabilization system can also be combined with a select camera's sensor-shift type image stabilization for more effective control of camera blur. A dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
