Next Level Speed

The second generation of speed, the Sony 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 shooting capabilities. And the updated construction now sports a more ergonomic shape, improved weather sealing, and better connectivity and transfer speeds.

Exmor RS BSI Stacked Sensor and BIONZ X Image Processor

24.2MP Full-Frame Stacked CMOS Sensor

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.

BIONZ X Processing and Electronic Shutter

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.

Autofocus and Image Stabilization

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 EV. The density of focusing points from this hybrid AF system also enables High-density Tracking AF Technology, which is adept at tracking moving subjects in a variety of lighting conditions. Updated AF algorithms also benefit maintaining critical focus on erratically or unpredictably moving subjects.

5-Axis SteadyShot INSIDE Image Stabilization

The a9 II incorporates an enhanced 5.5-stop effective 5-axis SteadyShot INSIDE image stabilization system, which compensates for five different types of camera shake encountered during handheld shooting of stills and video. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake.

For long focal lengths, the system will correct for pitch and yaw adjustments. Macro and high-magnification imagery, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will get usage out of the roll compensation. All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.

UHD 4K Video Recording in XAVC S Format

Internal recording of UHD 4K movies is possible in multiple frame rates up to 30 fps and, based on the Super35mm recording area and effective 6K resolution, oversampling renders greater detail and full pixel readout is possible, that is void of pixel binning, for higher quality imagery with reduced moiré and aliasing. Full-frame 4K recording has also been dramatically improved for improved quality when working at mid to high sensitivities to permit full use of the entire sensor width. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both resolutions utilize the 100 Mbps XAVC S format contained within an MP4 wrapper with 4:2:0 sampling. The high-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate set to either 30p or 24p. In addition to high-resolution internal recording, uncompressed HDMI output also enables the use of an optional external recorder for clean 4K recording with 4:2:2 sampling.
