The Sony a9 II is the second generation of speed, building on the excellent feature set of its predecessor by adding improved connectivity, a streamlined body design, and even faster performance. Utilizing the tried-and-true Exmor RS BSI stacked CMOS sensor and an upgraded BIONZ X engine, the a9 II offers very rapid and responsive performance.
a9 II specifications Shooting at up to 20 frames per second with a quiet electronic shutter or up to 10 frames per second with a mechanical shutter is supported, and the camera has a wide sensitivity range that extends up to an increased ISO 204800 if desired.
An autofocus system with 693 points has been included in the sensor’s architecture, which provides intelligent subject tracking as well as Real-time Eye AF, which ensures vital focus on moving subjects when shooting video. In addition to shooting at 20 frames per second, the BIONZ X can execute up to 60 AF/AE operations per second, allowing for more consistent results in rapidly changing settings.
In addition to still images, UHD 4K video recording at up to 30 frames per second is enabled, as is Quick and Slow Motion recording. Additional picture stabilization options include 5-axis SteadyShot INSIDE sensor-shift image stabilization, which may reduce the appearance of camera shaking by up to 5.5 stops.
In addition to enhanced imaging capabilities, the a9 II has received a significant physical redesign that includes a more ergonomic body form, increased weather sealing, and enhanced connectivity. A 3.69m-dot OLED EVF delivers a bright, clear, eye-level viewing means that is free of blackouts, allowing photographers to shoot at high continuous rates while using the camera.
The rear 3.0 is a 3.0 “Furthermore, the 1.44m-dot tilting LCD includes a touchscreen interface, allowing users simple control over shooting settings and video playback. Flexible file storage is made possible by the inclusion of two UHS-II SD memory card slots, and the a9 II is equipped with an enhanced 1000BASE-T Ethernet connector for quicker wired LAN sharing and remote camera control.
Wireless sharing and remote camera control are made possible by the integration of 5.0 GHz wireless sharing and Bluetooth technology. Additional to this, Voice Memos allows you to create audio snippets of up to 60 seconds in length to go along with each photo. These audio clips may then be automatically translated to text using the Transfer & Tagging app add-on and then incorporated into file metadata.
Exmor RS BSI Stacked CMOS Sensor with BIONZ X Image Processor for 24.2MP resolution.
The a9 II is designed for speed, and it does it by combining a 24.2MP Exmor RS BSI stacked CMOS sensor with an upgraded BIONZ X image processor, which results in an extremely speedy and responsive shooting experience.
Continuous shooting at up to 20 frames per second is feasible when using an electronic shutter, and 10 frames per second are possible while using a mechanical shutter. The sensor’s back-illuminated architecture additionally provides high sensitivity to an extended ISO 204800 while also reducing noise, resulting in crisp image clarity in a range of lighting environments.
Additional advantages of shooting in 14-bit uncompressed raw files include improved color accuracy and increased post-production flexibility, among other things.
Also working in conjunction with a high-speed front-end LSI, the BIONZ X processor allows for speedier processing times while also providing an extended dynamic range along with a smooth tone rendition. As a result of the fast recording capabilities, an equally quick AF/AE metering system has been developed, which operates at 60 times per second to continually review and evaluate and evaluate the scene in order to lock onto and follow moving subjects.
Additionally, automatic anti-flicker photography identifies and timing the shutter motion to reduce the flicker effect, resulting in more consistent results while photographing still photographs. Aside from that, the usage of an electronic shutter allows for completely blackout-free monitoring of moving subjects through the electronic viewfinder, which allows for more precise compositions of moving subjects.
A system with Hybrid AF with Quick Response Time
A Fast Hybrid AF system with 693 phase-detection points and 425 contrast-detection regions, which covers 93 percent of the picture area, allows for rapid and precise focusing in a variety of lighting circumstances with sensitivity down to -3 EV and is capable of shooting in low light.
With the high density of focusing points provided by this hybrid AF technology, High-density Tracking AF Technology is enabled, which is capable of tracking moving subjects in a range of lighting situations. Updated AF algorithms also profit from the ability to retain critical focus on subjects that move irregularly or unexpectedly.
Additionally, the use of phase-detection points permits the use of A-mount lenses with full continuous AF/AE tracking compatibility when using the optional LA-EA3 or LA-EA1 lens mount adapters, which are available separately.
For improved accuracy, the apt focus system is also capable of a variety of focusing functions. These include Lock-on AF, which maintains focus on moving subjects throughout the use of a configurable frame that is placed over the desired moving subject; and Expand Flexible Spot, which employs neighboring focus points to maintain focus on moving subjects even if the originally selected point loses focus.
When working in Focus Priority mode, the color of the focus frame may be selected between white and red, and AF tracking is feasible at apertures less than f/16 with certain lenses when working in Focus Priority mode. Additionally, Eye AF, which can be used to focus on identified human subjects’ eyes for portraiture, is available in both AF-S and AF-C modes and can be used for both stills and video.
It is accessible in both stills and video modes. When photographing animal subjects, eye AF may be utilized in any focusing mode and with any focusing mode when taking stills. When focusing on minute subject details, autofocus can be utilized in concert with the Focus Magnifier feature to achieve critical focus on the topic at hand.
It is also possible to utilize the back touchscreen for Touch Focus control, and a Touchpad Focus Control mode allows you to operate the rear touchscreen in an easy manner while keeping your gaze fixed on the viewfinder. Using AF-C mode, the focus point may also be adjusted while the shutter button is half-pressed, making it easier to swiftly alter focus without losing sight of the action.
