The Alpha a7R IIIA Mirrorless Digital Camera from Sony is a versatile, high-performance camera characterized by not only its resolution but by its multimedia versatility. This updated Fast Hybrid AF System employs a combination of 399 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.
Additionally, benefitting both stills and video operation, the a7R IIIA retains the 5-axis SteadyShot INSIDE sensor-shift image stabilization, which is now effective to minimize the appearance of camera shake by up to 5.5 stops. An updated rear 3.0" 2.36m-dot tilting touchscreen LCD is also available for intuitive settings control and to better support working from high and low angles. Suiting the camera's use in trying conditions, the magnesium alloy chassis and extensive weather-sealing also render the a7R IIIA dust- and moisture resistance. This sensor structure works with a 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.
