THE SONY A7R IV AND SONY A9 II CAMERAS
While both the a7R IV and the a9 II feature the same size sensor and body, they are two very different cameras. With the NA-α2020 Underwater Housing, you now can choose the right camera for the job while using the same housing, lenses and ports. Both cameras share 5-axis in-body stabilization (IBIS) providing up to 5.5 stops of stabilization and the ability to record 4K video either from the full sensor width or a Super35 crop at up to 30p to dual UHS-II SD card slots.
Both cameras are capable of clean HDMI video output up to UHD 4K 4:2:2 8-bit at up to 25p.
THE SONY A7R IV CAMERA
The Sony a7R IV is the company's fourth generation, high-resolution full-frame mirrorless camera. The 61.0-megapixel full-frame Exmor R CMOS sensor combined with BIONZ X imaging engine delivers unprecedented resolution, fine gradation, and low noise. Relative to previous generations, it promises more robust build quality, refined controls, the company's latest autofocus.
The a7R IV also received a serious upgrade from a7R III to its electronic viewfinder (EVF) in a 1.6x bump in resolution to an impressive 5.76-million-dots of UXGA OLED display, the highest of any mirrorless full-frame camera.
Sony Alpha a7R IV Key Specifications
- 61MP BSI CMOS full-frame sensor
- Fast Hybrid AF with tracking
- 10 fps burst shooting (12-bit Raw mode) with AF Tracking
- 5.76M dot OLED viewfinder
- 4K video from full sensor width (sub-sampled) or oversampled from Super35 crop
- S-Log 2, S-Log 3 and 'HLG' video modes (8-bit only)
THE SONY A9 II CAMERA
The a9 II is the flagship full-frame mirrorless camera in Sony's lineup and features a 24.2MP Exmor RS BSI CMOS sensor. The original a9 set the bar for high speed shooting with an incredible 20fps without EVF blackout, a trait passed on to the a9 II. It's 693 phase-detection pints cover over 93% of the sensor's surface which, combined with the BIONZ X processor leads to fast and accurate autofocus, even while tracking. Placing only 24.2 megapixels on the sensor, the a9 II prioritizes dynamic range and excellent low-light sensitivity over resolution.
Sony Alpha a9 II Key Specifications
- 24.2MP BSI CMOS full-frame sensor
- 20fps continuous shooting without EVF blackout
- Fast Hybrid AF with Tracking
- 3.69M dot OLED viewfinder
- 4K video from full sensor width (sub-sampled) or oversampled from Super35 crop
