Sony A7 R2

Sony A7R II (model ILCE-7RM2) is a full-frame mirrorless camera. The core selling point is the back-illuminated Exmor R CMOS sensor of about 42.4 million pixels, which was the world's first back-illuminated full-frame CMOS at that time. The fuselage has 5-axis anti-shake, 399 phase detection focus points, and supports 4K video recording in the machine. The overall parameters were very comprehensive at the time, and there were no obvious shortcomings. core parameter Sensor: Approximately 42.4 million effective pixels, full-frame Exmor R CMOS (back-illuminated), no low-pass filter, ISO expandable to 102400. Focus system: 399 phase detection focus points and 25 contrast detection focus points, covering about 45% of the picture range, and supporting eye focus (under continuous AF). Anti-shake: Built-in 5-axis image stabilization system, handheld shooting is more stable. Video: Supports 4K (3840 × 2160) video recording, adopts full pixel reading without merge output. Continuous shooting: autofocus tracking is about 5 frames per second, which is slow in high-pixel models. Shutter: Low vibration shutter design, life of about 500,000 times, support silent shooting (electronic shutter). merit The resolution brought by high pixels is very strong, and the advantages of scenes such as scenery and studio shots are obvious. The tolerance and high sense performance were excellent at that time. Sony's E-mount lens group is huge, with many choices from the original factory to the sub-factory, and there are also many cost-effective lenses. The 4K video capability was very prominent in Mirrorless back then, and both ends of the video and photos can be played.
