Unimagined subtlety

61.0-megapixel full-frame Exmor R™ CMOS sensor combined with BIONZ X™ imaging engine delivers unprecedented resolution, fine gradation, and low noise to open entirely new dimensions of detail just as pro photographers expect. The α7R IV captures the mood of each scene and the texture of aimed subjects.

61.0MP full-frame back-illuminated CMOS sensor

The newly developed Exmor R CMOS image sensor boasts incomparable high resolution. Back-illuminated design exhibits high sensitivity and low noise, despite extremely high pixel count of 61.0MP.

The latest image processing engine

The latest BIONZ X image processing engine works in tandem with front-end LSI to maximise high-resolution sensor performance while achieving up to 15-stop dynamic range at low ISO sensitivity.

Factors maximising superb resolution

In-body 5-axis image stabilisation

The in-body 5-axis image stabiliser algorithm is optimised to maximise high-resolution 61.0-megapixel image sensor performance. This fully supports your handheld shooting for reliability as effective as 5.5-stop higher shutter speed.

Shoot in absolute silence

Silent shooting not only provides a useful advantage in venues where quiet is required but avoids vibration that can cause camera-shake blur. Vibration-free shutter maximises extremely high α7R IV resolution for crisp clear images.

Striking response

The highest-level burst speed in its class

Regardless of remarkable image resolution, the α7R IV maintains its shooting speed of up to 10fps with a mechanical shutter (up to 8fps in live-view continuous shooting mode). This allows you to capture decisive moments - such as motion of wild animals - with subtle details made possible only by the 61.0MP high-resolution imaging capability.

Useful 26.2MP with APS-C cropping

Thanks to extraordinary image resolution, you can still maintain remarkable high-resolution images as approximately 26.2 megapixels even after cropping a full-frame image down into APS-C size. This means the α7R IV can help you proactively utilise 61.0-megapixel full-frame shooting, for example, in bird photography that tends to require cropping editing to magnify captured images.

Wide AF coverage

New image sensor supplies wide and high-density AF coverage with 567 phase-detection AF points (approx. 99.7% height and 74.0% width). 425-point contrast-detection AF supports precision focusing.

Fast AF despite higher resolution

Thanks to responsive enhanced Fast Hybrid AF, despite its large data handling, the α7R IV delivers swift AF even under dim lighting conditions, with remarkable ability to capture an aimed subject.

4D Focus

High-precision AF in underlit conditions

Advanced AF algorithms contribute to AF precision at light levels as low as EV-3. ‘Focus Priority in Aperture Drive’ option is for more accurate focusing in dim lighting and when aperture is stopped down.

Shoot up to 68 images continuously

Because buffer memory size is 1.5 times larger, the camera maintains burst shooting speed of up to approx. 68 images. With APS-C shooting mode, you can shoot approximately three times more photos than with full-frame shooting mode.

Dual media slots, both supporting UHS-II

Both SLOT 1 and SLOT 2 are compatible with UHS-I and UHS-II for fast mass-volume data writing. The α7R IV can simultaneously or relay record, separate RAW/JPEG data and stills/movies, and copy data between cards.

Technology basis for Real-time Tracking

Sony’s original AI (Artificial Intelligence) subject recognition technology and algorithm process large volume data captured by the image sensor in real time, tracking moment-to-moment subject changes with a high degree of accuracy. Colour, pattern, subject distance, human face and eye information are used for highly accurate subject recognition.

Maximised productivity in professional portrait shooting

Real-time Eye AF: evolution of portraiture

Real-time Eye AF represents the evolution of portrait shooting. This AI-aided technology provides immediate, accurate eye detection and tracking for crisp, clear focus on the subject’s face, even when capturing a fast-moving model in a photo session. The photographer can concentrate on composition for smoother workflow that counts with pros.

Instant focusing on an eye

When Face/Eye Priority in AF is on, simply half-press the shutter, press AF-ON button, or an assigned custom button. The camera takes care of focusing on a subject eye.

Right/left eye selection to meet your need

Now you can even select a specific eye - left or right - before or during shooting via custom button. Eye selection allows you to focus on composition, lighting, and other details.

More efficient workflow

Wireless and wired connective solutions for demanding pros

The α7R IV supports various options for PC Remote functions and means of data transfer including 5GHz Wi-Fi. Take full advantage of more choice and convenience in remote shooting operation and data backup.

Apply star ratings and image protection via the review playback display right on the spot. Jumping display at every 10/100 photos and group review of continuous shots are added conveniences.

Improved menu interface

Illustration of custom key settings on the menu screen makes it easier to understand usage. In addition, you can switch between menu tabs using the front dial or Fn button with one hand.

Steadfast AF tracking for stunning movies

Meet the rigorous autofocus demands of 4K movies with enhanced Fast Hybrid AF. You have high speed, precision, and tracking performance at your command for smooth, stable AF movie shooting. Adjust AF tracking sensitivity for steady focus.

Real-time Eye AF now for movie shooting

Real-time Eye AF newly supports movie shooting by detecting the subject’s eyes and continuing to track one eye. As the α7R IV keeps that eye in precise focus, you can concentrate on composition.

Touch Tracking for persistent focus on your subject

When shooting movies, touch a subject on the LCD monitor. The α7R IV begins focusing and following with Touch Tracking. If the α7R IV spots a human eye, Real-time Eye AF activates and tracks it, too.

Digital audio interface for clear sound recording

Digital audio interface enhances Multi Interface Shoe (MI Shoe). Use new ECM-B1M Shotgun Microphone or new XLR Adaptor Kit to record high-quality sound with minimised deterioration.

Newly developed 33.0MP back-illuminated CMOS image sensor

The full-frame Exmor R™ CMOS sensor delivers outstanding speed and superb image quality. The use of copper wiring contributes to higher transmission speeds and faster AD conversion, while fast sensor readout enables 10-bit 4:2:2 4K recording at up to 60p. The sensor also provides improved colour reproducibility, low-noise performance at all sensitivities, 15-stop dynamic range on stills, and increased AF precision and focal stability. 

BIONZ XR™ image processor for up to 8x processing speed

The BIONZ XR engine, also used in the flagship α1 and α7S III models, provides up to an 8x increase in processing speed. The engine concentrates real-time processing of AF, image recognition and image quality adjustment to minimise processing latency, for greatly increased movie and still processing power. User interface, network, and file management processing is distributed in order to deliver fast response regardless of real-time processing load. 

Beautiful image rendering with low noise

Visible benefits of the powerful new 33.0MP sensor and engine go beyond mere numbers. They include soft, natural-looking human skin textures, a stunning level of detail in landscapes and scenery, and better colour reproduction, with higher subjective resolution resulting from improved algorithms. The standard sensitivity range of ISO 100-51200 is expandable to ISO 50-204800 for stills and ISO 100-102400 for movies, with low-noise performance throughout.

Smoother gradation rendering with 10-bit HEIF recording

The α7 IV offers HEIF (High Efficiency Image File) still-image encoding, in addition to conventional RAW and JPEG. Smooth 10-bit gradations provide more realistic reproduction of skies and portrait subjects, and the use of 10-bit depth minimises degradation of image quality when editing. HEIF still images recorded in HLG mode can be played back on a compatible BRAVIA 4K TV, via an HDMI connection, to display images with an extraordinarily wide dynamic range. 

4K 60p recording, 4:2:2 10-bit recording 

The α7 IV gives you an impressive range of video recording options. Full pixel readout without binning allows 4K 60p recording, and when recording 4K movies at 30p, full-frame 7K oversampling produces high-resolution, highly detailed 4K. 10-bit 4:2:2 video can be recorded internally, allowing fuller, more natural gradations and greater editing freedom. The XAVC HS™ file format provides roughly twice the coding efficiency of MPEG-4 AVC/H.264. 

Set the mood, in-camera, with Creative Look

Broaden your creative palette with a selection of ten Creative Look presets. You can easily impart a particular mood in your still images, movies and live streaming, and all preset selections are available in-camera without post-editing, so you can share your vision immediately after shooting. 

Beautiful colour expression made simple, with S-Cinetone™ 

The α7 IV supports S-Cinetone, based on expertise gained through development of the VENICE CineAlta camera. This look is responsible for the beautiful skin tones for which Cinema Line cameras like the FX9, FX6 and FX3 are widely acclaimed. It delivers natural mid-tones for healthy-looking skin colour, plus soft colours and gorgeous highlights. Because it's in-camera, it's easy to create a more expressive look for your movie imagery without post-editing.

S-Log for colour matching with professional video equipment

The α7 IV provides S-Log2 and S-Log3 gamma curves, with the latter allowing capture of 15+ stops of dynamic range. The S-Gamut3 and S-Gamut3.Cine colour gamut settings make it easy to match α7 IV footage with footage from VENICE digital cinema cameras or Cinema Line cameras like the FX6 and FX3. The native sensitivity when shooting S-Log is ISO 800, and it can be lowered by as much as two stops (ISO 200-640) below the standard range to achieve extra low noise.

Soft Skin Effect for bright and beautiful skin appearance

The built-in Soft Skin Effect makes skin look more beautiful, softening wrinkles, blemishes and dull patches while preserving liveliness in eye and mouth areas. Complementing the capabilities of the full-frame sensor, this feature can add appeal to live-streamed sessions as well as enhancing still shots and movies. Four level settings are available, so you can adjust the degree of the effect as you wish. 

Optical 5-axis in-body image stabilisation for 5.5-step compensation 

The α7 IV's high-precision stabilisation unit and gyro sensors work with stabilisation algorithms to achieve up to 5.5 steps of shutter-speed compensation, to maximise the performance of the camera's 33.0MP sensor. This in-body stabilisation allows effective use with a wide range of lenses. The live monitor view shows the stabilised still image while the shutter button is half-pressed, an especially helpful feature when using a telephoto or macro lens, and it can be used in conjunction with the MF Assist and Focus Magnifier features.

Hand-held movie shooting with Active Mode

Active Mode uses the camera's stabilisation unit, gyro sensors and sophisticated algorithms for highly effective in-camera optical image stabilisation during movie shoots. The powerful processing engine precisely detects the required amount of compensation for smooth stabilisation in all formats, including 4K, without compromising the α7 IV's compact size and mobility. And, because the gyro data is also recorded alongside the video, even more effective post-production stabilisation can be applied for ultra smooth shots using Catalyst Browse/Prepare software. 

Buffer memory supports continuous shooting and recording

Both the mechanical and electronic shutters allow continuous shooting at up to 10 fps with AF/AE tracking. The latest powerful processing engine and increased buffer memory allow faster writing to memory cards, so you can shoot more than 800 uncompressed RAW+JPEG frames (more than 1600 altogether), or more than 1000 compressed RAW+JPEG frames (more than 2000 altogether, up to a full memory card). Increased processing power also allows you to change menu settings even while data is being written to the memory card. 

Fast Hybrid AF with improved speed, precision and tracking 

Using a combination of phase-detection AF and contrast-detection AF, Fast Hybrid AF focuses precisely even on small subjects or on people posed in front of a nighttime background. A wide, dense AF area covers roughly 94% of the image area for both still and movie shooting with 759 phase-detection points, while the contrast-detection AF system uses 425 points. This vast collection of data is analysed in real time by the latest powerful processing engine to achieve the AF system's impressive results. 

AI-based Real-time Eye AF and Real-time Tracking

The superior processing power of the BIONZ XR engine has led to improvements in both Real-time Eye AF and Real-time Tracking features. Improved face detection translates into 30% better eye-detection accuracy, while faster image processing yields higher accuracy when the subject is looking up, down, or sideways. Real-time Tracking allows you to select your subject and then leave tracking to the camera, relying on the latest subject recognition algorithm and high-speed analysis of spatial data by the processing engine.

Bird mode for Real-time Eye AF, now available in movies

The Real-time Eye AF function is now capable of detecting the eyes of birds and tracking them in real time, for both still shots and movies. The BIONZ XR engine runs optimised AF and tracking algorithms to ensure uninterrupted tracking even for birds in flight, whose movement is hard to predict. Once you've selected a bird, the camera will automatically detect and precisely track that bird's eye, whether the bird is perched or in flight.

AF control through touch operation

Touch Tracking lets you select a subject to track simply by touching the LCD screen, even while using the viewfinder, for more intuitive AF control for both still shots and movies. Easier focus operation is particularly helpful when you're shooting movies alone or using a gimbal, allowing you to concentrate on composing your shots. 

AF Assist for seamless transitions to manual focus

The AF Assist function, inherited from the Cinema Line FX6, lets you seamlessly switch to and from manual focus during movie shoots. When this feature has been turned on, rotating the focus ring temporarily switches operation from autofocus to manual focus to allow you to deliberately shift your focus to a different subject.

Visualise depth of field during movie shoots with Focus Map

The new Focus Map overlays focus information onto a live real-time display to show which areas are in or out of focus. Being able to clearly visualise depth of field in this way makes it easier to quickly set up your ideal focus point and depth of field during rehearsal. As a result you can use the camera's excellent video definition and fast lenses to create impressive shots with shallow depth of field. 

Breathing Compensation for consistent angle of view when focusing 

For the first time in the α series, the α7 IV provides compensation for focus breathing. Focus breathing is any change in a lens's angle of view that corresponds to changes in focus. Sony's original Clear Image Zoom technology is used to automatically maintain a consistent angle of view, for more movie-like focus transitions. This feature can be used in conjunction with Active Mode image stabilisation to shoot stable, consistent imagery.

Still/Movie/S&Q dial for quick access to hybrid capabilities

Befitting the α7 IV's status as a true hybrid camera, it comes equipped with a dedicated Still/Movie/S&Q dial to instantly switch between movies and stills. The dial switches the menus, functions, and custom settings of various controls between still and movie mode, and settings such as aperture and shutter speed are also maintained separately for stills and movies. S&Q mode can also be selected, for fast access to slow-motion or quick-motion shooting.

The latest mode-specific menus and customisable Rear dial R

The α7 IV's menus are specific to either stills or movies, and for easier navigation menus are configured to show three levels of hierarchy at once. Separate functions for stills and for movies can be assigned to various buttons and dials, including the new, freely customisable Rear dial R. With controls tailored to whichever shooting mode you are currently using, the flexible access provided by the Rear dial R contributes to greatly enhanced still and movie shooting efficiency.

Vari-angle LCD monitor for greater freedom when shooting

The large, side-opening 3.0-type 1.03-megadot touch-panel LCD monitor offers ample brightness for clear viewing in outdoor settings, and its 3:2 aspect ratio makes efficient use of the display area. The vari-angle mechanism allows flexible positioning and framing for handheld shots, gimbal-mounted or documentary-style self-shooting, or very low ground-level shots. 

3.68 megadot high-definition Quad-VGA OLED viewfinder

The α7 IV's Quad-VGA OLED viewfinder provides roughly 1.6 times the resolution of the α7 III viewfinder, with a 37.3° FOV and a 23mm high eyepoint. With high resolution, improved electronic viewfinder image quality, and fogging and dust resistance (including significantly improved internal fogging resistance relative to the α7 III), it is designed for clear and comfortable viewing in a wide range of shooting environments.

Communication features for easy sharing and distribution 

The α7 IV is equipped with robust wired and wireless communication features for more comfortable sharing and distribution. In-body wireless LAN uses a 5GHz band in addition to the 2.4GHz band, for fast data transfer. Background FTP transfer of files can be set to occur automatically while shooting continues, and a USB Type-C® connector supports fast SuperSpeed USB 10Gbps (USB 3.2 Gen 2) data transfer.

Instant real-time live streaming via USB connection 

Live streaming is as easy as connecting to a computer through a USB connection, and you can choose from four different output formats, including high-resolution 4K video. You can select whichever configuration is best for current network conditions and the devices used, and simultaneous internal recording is also available, giving you broad flexibility to cover a wide variety of needs.

High-capacity Z batteries and USB Power Delivery 

The α7 IV relies on a high-capacity Z battery (NP-FZ100), along with external power options that include USB power supplies and AC adaptors. Battery drain can be minimised by adding a high-capacity mobile battery for outdoor shooting. A USB charger or mobile battery that supports USB PD can be connected to the camera's USB Type-C® port, for extended recording.

Heat management

To allow extended continuous recording, efficient heat dissipation is provided by Sony's proprietary Σ (sigma)-shaped thermal mounting. The mounting, which is also used on flagship models, is constructed from a graphite material with excellent thermal conduction properties. This structure allows the image sensor, a major source of heat inside the camera body, to move freely during image stabilisation while heat is efficiently dissipated.

Dual media slots, with CFexpress Type A support

Dual media slots allow you to continue shooting even if one memory card fills up. One of the slots supports high-performance CFexpress Type A cards, and both slots support UHS-I and UHS-II SDXC/SDHC cards. With their fast write speeds, CFexpress Type A cards are particularly suited to high-speed continuous still shooting as well as high-resolution, high-bitrate 4K movie recording.

Reliable, robust engineering

We have improved the dust and moisture resistance of the α7 IV to provide outstanding reliability even in challenging outdoor shooting environments. Design refinements include more   sealing at body seams and the battery compartment cover (compared to the α7 III), a redesigned lens lock button, and extra cushioning around the mount. A lightweight, high-rigidity magnesium alloy used for the camera's top cover, front cover, and internal frame provides excellent durability.

Consideration for the environment and resource conservation 

Sony's "Road to Zero" environmental plan was launched in 2010 with the ultimate goal of achieving a zero environmental footprint. Currently nearly all  plastic packaging materials for the α7 IV are  recycled. Recyclable materials are also used for camera bodies whenever possible, reducing environmental burden without compromising functionality. While retaining state-of-the-art performance, we aim to further reduce energy and resource consumption to reduce the burden on the environment.
