Sony Alpha a7R IIIA Full-Frame Mirrorless Camera (Body Only)
Sony a7R IIIA is a high-performance mirrorless camera. It provides the best resolution, speed, and video capabilities. It features a back-illuminated design with a full-frame 42.2 megapixel Exmor R CMOS sensor. This works with the BIONZ X processor which offers high-resolution images and videos that minimize noise and improve speed.
To increase light collection and improve detail, this sensor structure combines a gapless on-chip lens design with an anti-reflection coating and does away with the optical low-pass filter.
The copper wiring layer is used for improving data transmission speed that creates a 14-bit high-resolution 42.4-megapixel sensitivity range from ISO 100-32000, which can be further expanded to ISO 50-102400,
It allows internal UHD 4K video recording. Here a sensor and processor combination is present. It helps to do fast continuous shooting with full resolution at up to 10 fps. The continuous shooting rate for a live view mode is up to 8 fps.
Image Stabilization
Sony a7R IIIA has a 5-axis SteadyShot INSIDE image stabilization system. It helps with the handheld shooting of stills and video. This offers a user to use any kind of lens. And make an image or video perfect from the camera shake. It helps to correct the pitch and yaw adjustment for a long focal length. 5-axes of stabilization functions all the time though the user used third-party lenses and adapters or lenses.
AF System
Sony a7R IIIA has a fast hybrid AF system that has double focusing speed and a tracking system. It has a 4D focus system that covers 68% of the frame and allows 425 contrast-detection area which helps for quick autofocus and subject tracking performance. Lock-on AF systems are reliable for focusing on moving subjects. Eye AF is available in both AF-S and AF-C modes that are used for recognizing human subjects’ eyes for portraits. The touch screen is used for touch focus control and this mode helps a user to use the rare screen intuitively. By switching in orientation, the user can get more focus control.The AF tracking sensitivity can be adjusted in five stages to match a subject’s movements.
UHD 4K Video Recording in XAVC S Format
Oversampled 4K video recording is also possible with this. It uses a 5K capture area.
LCD Screen
Standard and high-quality settings can be used based on shooting situations to optimize viewing incidents.
A dot-rated LCD is also included here which has a touch panel design for operating focusing control. The screen can tilt upwards and downwards to get benefits from a high and low angle.
Connectivity
A 3.5mm microphone input jack is compatible with external microphones.
A 3.5mm headphone jack is available for audio monitoring. Built-in wifi helps to share images to mobile devices, social media, and online via email and cloud storage.
Reliable Construction
The rate is 530 shots per charge with the EVF or 640 shots with the rear LCD. The double memory card slot makes it more flexible for storing files.
