Sony has launched their latest full-frame mirrorless camera which they named the Sony Alpha 7R V (A7R V). One of the features that this camera is proud of is the latest focusing system based on artificial intelligence (AI) technology.
Sony calls the new AI focus system Real Time Recognition. Even though it carries the same resolution as its predecessor (A7R IV), which is 61 MP, now the A7R V uses the newer Bionz XR processor.
The new type of processor can display more details and natural colors. Sony says that the Bionz XR processor enables the auto exposure performance of the A7R V to be 20% more reliable when compared to the previous model.
The Japanese company informed that the AF technology on its newest full-frame mirrorless camera has 693 points covering 79% of the sensor area. The AI tracking system is here to detect human poses and recognize the movements people make when evaluating subjects.
The sophistication of the AF system does not only detect eyes, heads and body parts; but also the nose, neck, shoulders, elbows, wrists, hips, knees, and ankles. I also feel myself that the Sony A7R V can still detect the head even though the subject is facing away from the camera. And, of course this is done very quickly and accurately.
The AI-based AF system can now improve Real-Time Eye AF performance by 60% and improve animal recognition by 40%. For animal AF, Sony says the A7R can detect dogs, cats and other domestic pets, as well as small animals such as insects.
The electronic viewfinder (EVF) on Sony's latest full-frame camera has a high resolution of 98.44 million dots based on OLED panel technology. With a high refresh rate, it seems as if this EVF is performing like an optical viewfinder.
Apart from the EVF, photographers can of course compose using the LCD screen on the back of the camera. This touch LCD screen has a size of 3.2 inches with a resolution of 2.1 MP. There is also a flexible hinge that allows the LCD to face the front of the camera (swivel) and tilt (tilt).
Sony equipped the A7R V with a 5-way in-body stabilization system (IBIS) and works with the onboard gyroscope to improve communication between the lens and body. The new processor allows the camera to shoot from ISO 100 to ISO 32,000, and can be increased up to ISO 102,400 for photos.
The Mirrorless A7R V has a significant improvement compared to the A7R IV in terms of video performance. The camera can now record up to 8K 24/25p for about 30 minutes and 4K 50/60p video recording.
