24.2MP Full-Frame Exmor RS CMOS Sensor BIONZ X Image Processor&Front-End LSI
693-Point Phase-Detection AF System
Up to 20 fps Shooting, ISO 100-204800
The second generation of speed, the Sony Alpha a9 II takes the impressive feature-set of its predecessor and adds enhanced connectivity, a refined body design, and even quicker performance. Utilizing the proven 24.2MP full-frame Exmor RS BSI stacked CMOS sensor and an updated BIONZ X processor, the a9 II sports especially quick and responsive capabilities. Up to 20 fps shooting is possible with a silent electronic shutter or up to 10 fps with a mechanical shutter is supported, along with a wide sensitivity range that reaches up to an expanded ISO 204800. The sensor's design also incorporates a 693-point phase-detection autofocus system, which offers intelligent subject tracking and Real-time Eye AF to ensure critical focus on moving subjects. The BIONZ X also performs up to 60 AF/AE functions per second to go along with the 20 fps shooting for reliable results in quickly changing situations. In addition to stills, UHD 4K video recording is supported at up to 30 fps and Quick and Slow Motion recording is also available. Additionally, 5-axis SteadyShot INSIDE sensor-shift image stabilization is available, too, which minimizes the appearance of camera shake by up to 5.5 stops.
Benefitting the imaging capabilities, the a9 II receives a dramatic update in its physical design, featuring a more ergonomic body shape, refined weather sealing, and improved connectivity. A 3.69m-dot OLED EVF provides a bright, clear eye-level viewing means and affords blackout-free viewing to support photographing at high continuous speeds. The rear 3.0" 1.44m-dot tilting LCD has a touchscreen design, too, for intuitive control over shooting settings and playback. Dual UHS-II SD memory card slots permit flexible file storage and the a9 II has been fitted with an improved 1000BASE-T Ethernet port for faster wired LAN sharing and remote camera operation. 5.0 GHz wireless sharing and Bluetooth are integrated, as well, for wireless sharing and remote camera control. Additionally, Voice Memos enables you to record up to 60-second sound clips with each photo, which can then be automatically converted to text, using the Transfer&Tagging app add-on, and then embedded into files' metadata.
24.2MP Exmor RS BSI Stacked CMOS Sensor and BIONZ X Image Processor
Built for speed, the a9 II utilizes a 24.2MP Exmor RS BSI stacked CMOS sensor, along with an updated BIONZ X image processor, that yields impressively quick and responsive performance. Up to 20 fps continuous shooting is possible using an electronic shutter or 10 fps shooting is supported with a mechanical shutter. The sensor's back-illuminated design also affords high sensitivity to an extended ISO 204800 with reduced noise for clean image quality in a variety of lighting conditions. Additionally, uncompressed raw files can be recorded in 14-bit for greater color fidelity and post-production flexibility.
The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times along with a wide dynamic range with smooth tonal rendering. Benefitting the fast recording capabilities is an equally quick AF/AE metering system that functions at 60 times per second to continuously evaluate the scene in order to lock onto and track moving subjects. Automatic anti-flicker shooting also recognizes and times the shutter action to minimize the flicker effect for more consistent results on still images. Additionally, due to the use of an electronic shutter, totally blackout-free monitoring is possible with the electronic viewfinder for more accurate compositions of moving subjects.
Fast Hybrid AF System
Covering 93% of the image area, a Fast Hybrid AF system incorporates 693 phase-detection points along with 425 contrast-detection areas for quick and precise focusing in a variety of lighting conditions with sensitivity down to -3
