FEATURES

A fusion of leading technologies delivers overwhelming performance


The massive volume of data from the 50.1 megapixel[FN|Approximate, effective.] full-frame Exmor RS™ image sensor is processed in real time by Sony’s BIONZ XR™ image processing engine. An advanced AI processing unit applies high-level subject recognition to reliably recognise a wide range of subjects. These state-of-the-art technologies make it easy to capture even the most challenging subjects in extraordinary resolution, with blackout-free viewing and full AF/AE tracking at up to 30 fps.[FN|When using electronic shutter. Sony test conditions. Maximum continuous frame rate may be lower in some shooting conditions. Continuous shooting speed may vary depending on the lens used in AF-C focus modes. Visit Sony’s support web page for lens compatibility information.]

An advanced AI processing unit achieves high-level subject recognition


The a1 II features a dedicated AI processing unit that helps to recognise people more accurately based on human pose estimation, and also supports recognition of a wide range of subjects other than people, such as animals, vehicles and insects,[FN|Available subject settings are: Auto, Human, Animal/Bird, Animal, Bird, Insect, Car/Train, and Airplane. Subject types other than the type specified may be erroneously recognised in some cases.] with high accuracy. This results in a dramatic improvement in Real-time Recognition AF and Real-time Tracking capability, and higher overall AF performance.

Human eye recognition improved by up to approximately 30%


Real-time REcognition AF has improved human eye recognition by approximately 30%[FN|Compared to the a1. Sony tests.], and its human pose estimation technology also delivers precise recognition of subjects facing away from the camera, wearing sunglasses, or with the face obscured. Recognition of distant human subjects occupying only a small part of the frame has been notably improved, so approaching subjects are recognised and tracked sooner. Subjects can also be tracked better across occlusions among many people.

A wide variety of subjects accurately recognised[FN|Available subject settings are: Auto, Human, Animal/Bird, Animal, Bird, Insect, Car/Train, and Airplane. Subject types other than the type specified may be erroneously recognised in some cases.][FN|Car/Train, and Airplane example images shot with a camera with the same Real-time Recognition AF system.]


A wider variety of subjects[FN|Available subject settings are: Auto, Human, Animal/Bird, Animal, Bird, Insect, Car/Train, and Airplane. Subject types other than the type specified may be erroneously recognised in some cases.] is now recognised for stills and movies, with a new [Auto] mode letting the camera select.[FN|When Auto is selected the camera will normally recognise the subject type automatically, but the wrong type may be selected in some situations. In such cases manually selecting the intended subject type may solve the problem.] Recognition of animals overall is improved by approximately 30%[FN|Compared to the a1. Sony tests.], with eyes of some small animals added, and the eyes, heads and faces of animals like dogs and cats recognised. Recognition of birds is improved by 50%[FN|Compared to the a1. Sony tests.].

Reliable Real-time Tracking[FN|[Tracking] in the menu.]


The a1 II features AI-based Real-time Tracking.[FN|[Tracking] in the menu.] If the subject cannot be recognised for some reason, or subject recognition AF is not turned ON, Sony’s original subject recognition algorithm will process colour, pattern, and spatial data to ensure that the subject is reliably acquired and tracked. If [Touch Tracking] is engaged, touching a subject on the monitor will instantly select it for tracking.

AF tracking response settable to match subject speed changes


Fast Hybrid AF combines phase detection and contrast detection for superb speed, precision and tracking performance. 759[FN|For still images. The number of points varies according to the shooting mode.] phase-detection points cover 92% of the image sensor. The AF tracking response for stills can now be selected from [Stable], [Standard], and [Responsive] to suit the likely subject motion, useful for example in bird photography. High AF precision is achieved right down to light levels as low as EV-4.0[FN|ISO 100 equivalent, F2.0 lens.] in AF-S mode, with improved contrast AF response.

Flexible focus area settings


XL and XS focus area spot sizes are now available in addition to the existing L, M, and S. XS can be useful to avoid focusing on foreground objects such as branches. It is also possible to create a custom focus area of specified size and aspect ratio, useful in situations like a track event where athletes are lined up side-by-side and you want to focus on the leading runner.

High-speed continuous shooting at full 50.1 MP[FN|Approximate, effective.] resolution


High-speed continuous shooting at up to 30 fps[FN|When using electronic shutter. Sony test conditions. Maximum continuous frame rate may be lower in some shooting conditions. Continuous shooting speed may vary depending on the lens used in AF-C focus modes. Visit Sony’s support web page for lens compatibility information.] with full AF/AE tracking is possible at a stunning 50.1 MP[FN|Approximate, effective.] resolution, with up to 120 AF/AE calculations per second[FN|At shutter speeds of 1/125 sec. or higher. May be less depending on shooting conditions and the lens used.] on the data from the image sensor. Blackout-free shooting with no loss of viewfinder image allows seamless framing and capture of the subject as if viewed with the naked eye.

Pre-Capture and Continuous Shooting Speed Boost


Pre-capture retroactively captures moments that occurred before the shutter was released[FN|Maximum pre-capture time may be less in some situations.][FN|High continuous shooting speeds can cause an increase in camera temperature. Pre-capture may be limited to protect the device in high ambient temperature conditions.], without compromising resolution, even when shooting continuously at up to 30 fps[FN|When using electronic shutter. Sony test conditions. Maximum continuous frame rate may be lower in some shooting conditions. Continuous shooting speed may vary depending on the lens used in AF-C focus modes. Visit Sony’s support web page for lens compatibility information.] with selectable recording time options. Continuous Shooting Speed Boost can temporarily change the burst speed. Both features reduce the chance of missing that vital instant.

Enhanced high-resolution burst stamina


A large buffer memory and increased overall system speed allow continuous shooting at full resolution. Up to 159 JPEG images[FN|Recording to Sony CEA-G160T CFexpress Type A memory card (sold separately). Sony tests.] or 153 compressed RAW images[FN|Recording to Sony CEA-G160T CFexpress Type A memory card (sold separately). Sony tests.] can be captured in one continuous 30 fps[FN|When using electronic shutter. Sony test conditions. Maximum continuous frame rate may be lower in some shooting conditions. Continuous shooting speed may vary depending on the lens used in AF-C focus modes. Visit Sony’s support web page for lens compatibility information.] burst. Up to 400 JPEG images can be captured in one 20 fps burst. This can be a huge confidence-booster when timing is critical for sports, wildlife, and other moving subjects.

Selectable release time lag


Selectable release time lag modes are available via the [Release Lag] / [Start Display] menu. With blackout occurring on only the first image in a continuous burst, [Fastest Release/On] provides the shortest possible release time lag, while [Stable Release/On] minimises variations in release time lag making it easier to release the shutter at the intended moment. The default [Auto/Off] setting gives no blackout when shooting is started.

Stunning resolution with 50.1 megapixels[FN|Approximate, effective.]


Sony’s extensive high-performance G Master line work with the 50.1 megapixel[FN|Approximate, effective.] Exmor RS image sensor and BIONZ XR image processing engine to create deep, lifelike, high-resolution rendering. The sensor’s high pixel count means that resolution is still a very impressive 21 megapixels when shooting in APS-C mode or cropping to APS-C size after shooting.

Selectable RAW image size and quality


Compressed, Uncompressed, and high-compression Lossless Compressed RAW still images are provided. Compressed RAW images can be shot continuously at up to 30 fps. Three Lossless Compressed RAW image sizes can be selected to suit the application: L, M, and S. Lossless Compressed RAW, JPEG, and HEIF images in M and S size have the same number of pixels whether shot in the full-frame or APS-C mode, making it possible to seamlessly switch modes while maintaining the same image resolution. JPEG and RAW sizes can be freely mixed and matched to meet the needs of the application.

High sensitivity, low noise, and wide dynamic range


Feedback from professionals has been taken into account to create noise reduction that is highly effective without sacrificing image detail, so users can shoot clear images of indoor sports at mid to high sensitivity without hesitation. Dynamic range at lower sensitivities is an impressively wide 15 stops[FN|When shooting stills. Sony test conditions.] for smooth, realistic gradations.  [1] a1,  ISO 6400, 1/1600s, F2.8  [2] a1 II,  ISO 6400, 1/1600s, F2.8

Consistently accurate exposure and colour


Exposure and colour reproduction are notably improved compared to the a1. The AE algorithm detects faces and optimises exposure for stills and movies. Exposure stability has been improved by approximately 20%[FN|Sony tests.], even when the face is backlit and dark, or over-illuminated in direct sunlight, or not facing the camera. Working with a “Visible Light and IR Sensor” on the front of the body, the advanced AI processing unit helps to achieve accurate white balance even where the subject is in shade.

Optical 5-axis image stabilisation achieves 8.5-step performance at the centre[FN|CIPA 2024 standards. Pitch/Yaw/Roll compensation. FE 50mm F1.2 GM lens. Long exposure NR off.]


A high-precision image stabilisation unit, advanced gyro sensors, and leading-edge algorithms detect and correct camera shake, achieving a groundbreaking up to 8.5-step effect at the centre and 7.0-step at the periphery, and transforming handheld shooting with precision down to the single-pixel level and the finest subject details. With compatible lenses that include built-in stabilisation[FN|See Sony’s support web page for information on compatible lenses:https://www.sony.net/dics/fnc1002/ A software update may be required for some lenses. Stabilisation may vary according to the lens used.], improved body-lens synchronisation provides effective blur control even at otherwise problematic telephoto focal lengths. [1] Yaw [2] Roll [3] Pitch

Composite RAW modes for lower noise and higher resolution


The NR Shooting Settings mode[FN|The latest version of the Imaging Edge Desktop™ applications is required for compositing. The lowest allowable shutter speed for NR Shooting Settings mode is 1/30 sec. The flash mode is fixed at Off and some functions such as Pre-Capture and Continuous Speed Shooting Boost are not available.] captures between 4 and 32 RAW images which can then be composited using Sony’s Imaging Edge Desktop™ application to create a full-resolution image with very low noise even at mid to high sensitivities. Pixel Shift Multi Shooting[FN|The Imaging Edge Desktop™ Viewer and Edit applications are required for compositing. Image compositing may not be successful if camera or subject movement causes blur. The use of a tripod is recommended, as is the use of PC tethered control or a remote commander. Uncompressed RAW and electronic shutter are automatically selected for Pixel Shift Multi Shooting. Some restrictions apply to flash and other devices.] captures 4 or 16 pixel-shifted images that are later composited with the same PC application to achieve overwhelming resolution[FN|Four 49.7-megapixel images provide approx. 199 million pixels, and sixteen 49.7-megapixel images provide approx. 796 million pixels. Image size after compositing is approx. 49.7 million (8640 x 5760) pixels for 4-image shots, and approx. 199 million pixels (17280 x 11520) for 16-image shots.] in a single image.  [1] Single RAW image, ISO 12800  [2] NR composite RAW (32 images), ISO 12800

Real-time Recognition AF for movies


Real-time Recognition AF utilises advanced AI-based human pose estimation technology that recognises and tracks not just eyes, but body and head position for human subjects with high precision. The range of subjects recognised with AI assistance, for both movies and stills, has been expanded relative to the a1, and now includes birds in movies for example[FN|Available subject settings are: Auto, Human, Animal/Bird, Animal, Bird, Insect, Car/Train, and Airplane. Subject types other than the type specified may be erroneously recognised in some cases.]. Other subjects are acquired and tracked in real time by processing colour, pattern, and spatial data.

High-resolution 8K[FN|When recording 4K 120p/100p or 8K movies, [APS-C S35 Shooting] is fixed [Off]. 35mm full-frame lenses are recommended. HDMI output format is limited to 4:2:0 8bit.]/4K recording for impressive realism


4K (3840 x 2160) movies can be cropped and edited from 8K source footage with overwhelming resolution from 8.6K oversampling. 8K 4:2:2 10-bit XAVC HS recording with optional Full HD proxy is available, as are 4K recording in XAVC HS, S, or S-I formats in full-frame, or Super 35mm size oversampled from 5.8K with full pixel readout and no pixel binning. XAVC S-I allows recording at up to 600 Mbps for outstanding image quality.

High frame rate recording at up to 120p[FN|With approx. 10% image crop. When recording 4K 120p/100p or 8K movies, [APS-C S35 Shooting] is fixed [Off]. 35mm full-frame lenses are recommended.]


4K can be recorded at up to 120p right in the camera. 4K footage can be played back in up to 5x slow motion[FN|Post-production editing and S&Q mode recording are required.]. The Slow & Quick Motion (S&Q) mode[FN|Audio recording not available in S&Q mode.] makes it convenient to play recorded footage back at slow or high speed in the camera. Full HD footage recorded at 240 fps offers even greater range: up to 10x slow motion (24p) to create impressive sports movies, for example. The frame rate setup menu allows intuitive selection of frame rates.[FN|Recording frame rates are listed as integer values, but the actual frame rates are as follows: 24p = 23.98 fps, 30p = 29.97 fps, 60p = 59.94 fps, and 120p = 119.88 fps.][FN|Data must be recorded to a CFexpress Type A memory card when recording XAVC S-I at 120 fps / 100 fps or higher.]

Better S-Log matching with Cinema Line cameras


The S-Log3 gamma curve emphasises gradation characteristics from shadows to mid-grey (18% grey). Minimum ISO when shooting S-Log is 800, while the expanded ISO range is 200 - 640. Compared to the a1, detail reproduction has been improved and footage can be more easily matched with the output from digital cinema cameras that also offer S-Log3 such as Sony’s VENICE and BURANO. The ability to import User LUTs into the camera makes it easy to get an idea of the final post-edit look right in the camera.

Dynamic active Mode stabilisation [FN|Active Mode and Dynamic active Mode are not available when shooting 8K movies or at frame rates of 120 fps or higher.][FN|Angle of view is reduced in Active Mode. In Dynamic active Mode angle of view is reduced more than in Active Mode.][FN|Clear Image Zoom is not available when using Dynamic active Mode.]


In addition to standard mode, Active Mode combines a precision image stabilisation unit and gyro sensor, while Dynamic active Mode adds electronic stabilisation for an additional approximately 30%[FN|Sony tests.] effect[FN|Active Mode and Dynamic active Mode are not available when shooting 8K movies or at frame rates of 120 fps or higher.][FN|Angle of view is reduced in Active Mode. In Dynamic active Mode angle of view is reduced more than in Active Mode.][FN|Clear Image Zoom is not available when using Dynamic active Mode.], enabling stable recording even when the user is jogging.

Breathing compensation[FN|Compatible lenses are listed at: https://www.sony.net/dics/breathing/]


Focus breathing compensation[FN|Compatible lenses are listed at: https://www.sony.net/dics/breathing/] effectively reduces focus breathing when shooting movies. Sony’s original Clear Image Zoom technology is used to automatically maintain a consistent angle of view throughout focus changes for more stable images. Breathing metadata can also be used with the advanced breathing compensation capabilities of the latest Catalyst Browse/Catalyst Prepare/ Catalyst Prepare Plugin software application during post production.

Features for smooth focusing


A range of focusing tools support intuitive and professional movie making. AF Assist[FN|Not available in the following conditions: when Focus Magnification is active, during digital zoom, during USB streaming, when no lens is mounted, when an A-mount lens is mounted, or when a lens that is not compatible with focal plane phase-detection AF is mounted.] for temporary switching to manual focus, focus peaking display, and AF transition speed and sensitivity settings all help the user when shooting movies. Focus Map overlays a visual depth-of-field map on the live view display. Real-time Recognition AF, Real-time Tracking, and Focus Area are now available during digital zoom and Clear Image Zoom operation.[FN|Movie and S&Q modes only.]

Auto Framing automatically adjusts composition for the subject


Using AI-based subject recognition technology, Auto Framing[FN|Only available for movies. Framing is cropped from 4K images, resulting in reduced angle of view.] automatically crops the frame to keep the subject in a prominent position when shooting movies. The framing is continually adjusted so that the recorded footage looks like the subject was being followed by an experienced camera operator. The timing at which Auto Framing begins, the size of the subject in the frame, and the tracking speed can be controlled. Auto Framing can be ideal for recording interviews, music performance, cooking, and much more.

Framing Stabilizer automatically maintains subject position


Framing Stabilizer[FN|Only available for movies. Framing is cropped from 4K images, resulting in reduced angle of view.] automatically maintains subject location within the frame when the camera operator is moving alongside the subject or in other situations where maintaining consistent framing can be difficult. AI-based subject recognition and Dynamic active image stabilisation maintain the composition and achieve stable imagery even when shooting handheld. [Center] mode automatically keeps the subject in the centre of the frame, while [Manual] mode lets subject position be freely specified.

Flexible LCD monitor positioning


The 4-axis multi-angle monitor can be positioned for optimal viewing in horizontal or vertical orientation. The extended monitor can be tilted upward by approximately 98° and downward by approximately 40° to the camera back, and sideways by a full 180°. The hinge is unobtrusive but robust.[FN|Do not apply excessive force when opening or rotating the monitor.] The large 3.2 type 2.1 million dot display panel is touch sensitive, has a wide colour gamut, and is designed for clear outdoor viewing.

High-performance electronic viewfinder


A 9.44 million-dot (approx.) electronic viewfinder with high-definition OLED display and refined optics delivers clear viewing. Magnification is 0.90x[FN|50mm lens, infinity, -1m-1 dioptre.] with a 41° FOV for a clear, wide view, the updated structure giving a 25 mm high eyepoint.[FN|Distance from last optical surface, -1m-1 dioptre (CIPA standard)] Time lag has been reduced for more stable framing. The finder frame rate for shooting stills can be set to [Standard] (60 fps), [High] (120 fps), or [Higher] (240 fps).[FN|When [Finder Frame Rate] is set to [Higher], viewfinder resolution and display magnification are reduced. When [Finder Frame Rate] is set to [Higher], [Display Quality] is locked to [Standard].] Overall image quality has been significantly improved and aberration minimised.

Standard and deep viewfinder eyecups provided


The a1 II is supplied with two viewfinder eyecups: the standard FDA-EP19 type and a deep FDA-EP21 type that the user can choose according to ambient conditions or personal preference. The new FPA-EP21 design is deeper than the standard FDA-EP19 type, enhancing viewing clarity by effectively blocking extraneous light that can enter between the eye and eyecup in bright shooting environments. The soft, close-fitting material and design enhance viewing comfort.

Advanced grip hold and ease of use


The improved grip ergonomics ensure comfortable and stable shooting over long sessions with a shape that allows firm holding in the palm of the hand. A C5 custom button has also been added, and the grip design is replicated for prolonged vertical shooting with the optional VG-C5 Vertical Grip[FN|Sold separately https://www.sony.co.uk/electronics/interchangeable-lens-cameras-vertical-grips/vg-c5], which additionally offers extended battery life over the previous model.

Supplied charger charges two NP-FZ100 batteries in 155 minutes[FN|One NP-FZ100 battery is supplied with the camera. USB PD compatible power supply and USB cable are not included. Simultaneous two-battery charging requires a USB PD compatible power supply that can deliver 30 watts or higher. Single-battery charging requires a USB PD compatible power supply that can deliver 18 watts or higher. A USB cable that can handle 3 amps or more is required in both cases. Charge time may vary according to use conditions.]


The supplied BC-ZD1 quick charger can simultaneously charge two NP-FZ100 batteries in approximately 155 minutes.[FN|One NP-FZ100 battery is supplied with the camera. USB PD compatible power supply and USB cable are not included. Simultaneous two-battery charging requires a USB PD compatible power supply that can deliver 30 watts or higher. Single-battery charging requires a USB PD compatible power supply that can deliver 18 watts or higher. A USB cable that can handle 3 amps or more is required in both cases. Charge time may vary according to use conditions.] when used with an AC adaptor providing USB PD (Power Delivery) power. This charger is ideal for charging two batteries for use at events or in other applications that require continuous operation over extended periods of time.

Dual slots support CFexpress Type A memory cards


The a1 II has two media slots that both support CFexpress Type A memory cards as well as UHS-I and UHS-II SD cards. CFexpress Type A cards are ideal for recording the huge volume of data produced by the image sensor, allowing 30 fps[FN|When using electronic shutter. Sony test conditions. Maximum continuous frame rate may be lower in some shooting conditions. Continuous shooting speed may vary depending on the lens used in AF-C focus modes. Visit Sony’s support web page for lens compatibility information.] continuous still shooting and high-bitrate 8K and 4K movie recording. The same data can be simultaneously recorded to both cards, or files can be separated by type and size. A “relay” mode automatically switches recording to the second card when the first becomes full.

Image playback functions that support immediate-delivery workflows


Multiple media playback lets you seamlessly display all images on two memory cards by selecting all slots as the display target during playback. Group display of images such as those shot continuously or with interval shooting is also supported. And if set in advance, a rating can automatically be applied to the first image in continuous burst or Pre-Capture groups, or a divider image inserted before the first image in groups, enabling quick scrolling through and location of groups using the custom dial during playback.

Dedicated microphone for clear voice memos


A dedicated voice memo microphone is built into the rear panel, making it easy to record clear voice memos even in noisy environments. These can be transferred to an FTP server along with the corresponding images, allowing the photographer to communicate effectively to the editor, or the Transfer & Tagging mobile application can be used to convert the voice memos to text prior to transfer.[FN|When Google service is available.] Either approach can significantly speed up the delivery workflow.

IPTC metadata embedding and presets


IPTC (International Press Telecommunications Council) metadata can be added to still images. IPTC information can be written to IPTC metadata presets and loaded into the camera via a memory card. The a1 II can internally store up to 20 presets that can then be quickly selected when needed. This can be extremely useful at multi-sports events, for example, where different IPTC information is required for different competitions. The appropriate preset can be easily selected in-camera.

Efficient data transfer by high-speed wired LAN and wireless LAN


Still image and movie files can be directly transferred from the camera to a specified remote FTP server via wired and wireless LAN. 2.5GBASE-T wired LAN connectivity allowing data transfer at up to 2.5 Gbps is now provided for stable, high-speed transfer of still and movie data from the camera to an FTP server and stable communication for PC Remote shooting. Built-in Wi-Fi (IEEE 802.11a/b/g/n/ac) with 2x2 MIMO support allows high-speed 5 GHz[FN|5 GHz communication may be restricted in some countries and regions.] wireless communication with maximum speed and stability for news and sports shooters who need to deliver immediately via FTP, as well as for studio environments.

USB Type-C ® connector supports SuperSpeed USB 10 Gbps (USB 3.2)


A USB Type-C ® connector that supports fast SuperSpeed USB 10 Gbps (USB 3.2) data transfer is provided. This makes high-speed PC Remote (tethered) data transfer available for smooth handling of large image files.

Tools that support professional workflow


The a1 II is compatible with Transfer & Tagging and Remote Camera Tools. Transfer & Tagging is a smartphone application[FN|For details please refer to: https://www.sony.net/ttad/] that can speed up still-image workflows for professional sports and news photographers, allowing background FTP transfers to smartphone as well as fast tag/caption attachment, while Remote Camera Tool is a software application that allows PC Remote (tethered) shooting via wired LAN.

Creators' Cloud platform


Creators' Cloud is a platform that supports creative work from shooting to production by combining Sony's advanced camera technology and the cloud. It's also a place for discovery and collaboration with other creators around the world. Explore web, mobile, and PC-based apps providing efficient solutions that integrate cameras with shooting and production apps and services.

Sony's goal: zero environmental footprint


Sony's environmental plan 'Road to Zero' is designed to reduce the Group's environmental footprint to zero by 2050. Avoiding non-renewable resources, we actively use recycled plastics in cameras, including our durable, high-quality SORPLAS™ material[FN|Depending on the time of production, SORPLAS™ may not be used for some parts.]. Sony is also moving away from plastic packaging. The a1 II is the first high-end a-series product to be shipped in a plastic-free package made of Sony’s “Original Blended Material” that can be recycled as paper.[FN|This product packaging is recyclable in communities that have appropriate recycling programs.]

Greater accessibility for all users


Accessibility features such as Screen Reader[FN|Availability varies depending on region and language.] that reads menu screen text aloud, Enlarged Menu Display, and others make it easier for everyone to enjoy shooting and playback using the a1 II. Furthermore, advanced features like AI-based Real-time Recognition AF for a wide range of subjects, intuitive touch operation for subject tracking, and many more make the joys of photography and moviemaking available to the widest possible range of users.
