61 Megapixel full-frame CMOS sensor

The A7R IV features Sonys newly developed 35mm full-frame back-illuminated CMOS sensor with 61 megapixels. The large megapixel count enables the camera to attain image resolution expected only in medium-format cameras. Thanks to the cameras mirrorless design, the absence of mechanical mirror shock reduces any unwanted shake to maximize sharpness for the high resolution. The sensors large size, coupled with smart image processing algorithms provides up to 15 stops of dynamic range as well as a wide light sensitivity range of ISO 50-102400.

Enhanced high speed BIONZ X image processor: 10 FPS burst with AF/AE

Despite the A7R Mark IVs high resolution of 61.0 MP, a powerful image processor with intelligent algorithms enables the camera to shoot high-speed continuous bursts of up to 10fps up to approx. 68 images while maintaining autofocus and autoexposure.

In-body 5-axis image stabilization rated up to 5.5-stops

All the resolution in the world means nothing if your image isnt sharp or your video not stable. For this the camera features an in-body stabilisation system that compensates for five types of camera shake that tend to blur images or ruin video: pitch/yaw shake when shooting at longer focal lengths; X/Y shake in close-up (including macro) shooting; and roll shake when recording stills at night and movies. It effectively achieves 5.5 stop-faster shutter speed, so the Sony A7R Mark IV can take full advantage of its large 61-megapixel count and live-view image performance. Additionally, the 7R IV incorporates an internal damper structure to absorb the impact of shutter motion for minimum shutter vibration. Furthermore, it functions with A-mount lenses attached via mount adaptor, as well as E-mount lenses.

16-bit processing with 14-bit RAW output

The 7R IV Image sensor output is processed in 16-bit form by the front-end LSI to output either a compressed or uncompressed 14-bit RAW file. The vast range image data stored in the file enables greater colour and exposure flexibility in post-production.

5.76-million-dot UXGA OLED viewfinder

Newly featured in the 7R IV, this 5.76-million-dot electronic viewfinder provides high-precision, high-brightness and high-contrast visibility, reproducing fine detail with 1.6 times higher resolution than 7R III. "High Display Quality" mode draws on the effective 61.0 MP (approx.) image sensor to suppress moir and jaggies for highly precise and natural images on the viewfinder; 120/100fps of "High" finder frame rate mode shows smoother motion, so its simpler to trace moving subjects. Fluorine coating makes it easier to remove dirt or a fingerprint from the lens, for more comfortable viewing in inclement weather and better concentration on shooting.

567-point phase-detection AF and 425-point contrast-detection AF

Thanks to increased coverage and density of AF points and enhanced algorithm for tracking moving subjects, overall AF performance has evolved to provide steadfast, accurate tracking of complex subject motion and speed changes. The 7R IVs Fast Hybrid AF system combines high-speed, highly trackable phase-detection and high-precision contrast-detection autofocusing, even for shooting venues as dimly lit as EV-3. 567-point phase-detection AF and 425-point contrast-detection AF provide wider image area coverage of 99.7% height and 74.0% width. In addition, this remarkable AF system provides as rapid a response as 7R III, despite mass data handling due to the extremely high-resolution CMOS sensor, even in dim shooting venues.

Anti-flicker shooting

Flicker from fluorescent and other artificial lighting is automatically detected and shutter action is timed to minimize the effect of flicker on still images. This suppresses exposure and color anomalies at the top and bottom of images shot at high shutter speeds, as well as exposure and color inconsistency between continuous shots, so you can take images indoors with more confidence.

Dual media slots, both supporting UHS-II

The Sony A7R IV provides two media slots for SD cards, both SLOT 1 and SLOT 2 are now compatible with UHS-I and UHS-II for fast mass-volume data writing. Two cards in the slots can be used to simultaneously record or relay record data, separate RAW data from JPEG data, or stills from movies, and copy data from one card to the other. A slide lock structure prevents the memory card cover from being opened unintentionally.

Up to 670 shots or 170 min video

The 7R IV employs the large-capacity NP-FZ100 battery just like 7R III. Due to a more energy-efficient circuit design, the 7R IV matches 7R III usage level longevity, despite the higher resolution of the 7R IV image sensor and EVF. An optional Vertical Grip (VG-C4EM) can hold two batteries and an optional Multi Battery Adaptor Kit (NPA-MQZ1K) can hold up to four batteries for even longer hours of shooting. In addition to using such optional accessories, USB Type-C and Multi/Micro USB ports allow external mobile batteries to power the camera for further extended recording.

Enhanced Real-time Eye AF

Real-time Eye AF works in tandem with Real-time Tracking technology, based on the latest evolutionary advances in artificial intelligence, for highly efficient portrait shooting. This progressive system detects and processes face and eye data in real time, and stays locked onto the eye of the subject with unprecedented precision. When "Face/Eye Priority in AF" is ON, Eye AF (AF-C/AF-S/AF-A mode) can be activated not only through a custom key assignment, but also by half-pressing the shutter button or pressing the AF-ON button. This function now allows you to choose a particular eye left or right, in advance or during shooting. Real-time Eye AF supports movie shooting in addition to stills.

Real-time Eye AF for animals and pets

Advanced AI-based subject recognition in Sonys Real-time Eye AF includes a new algorithm supporting animal tracking for fast, precise, automatic detection and tracking of an animals eye. This new capability will greatly increase your success rate when shooting pictures of animals in the wild or beloved pets at home, situations where accurate focus has been a challenge. All AF-C, AF-S, and AF-A focus modes are supported.

Real-time Tracking holds the focus on tracked subjects

With this technology, accurate focus is maintained automatically while the shutter button is half-pressed. You can select a subject as you intend, rely on the 7R IV, and concentrate on your composition since the camera takes care of subject tracking. A newly adopted Real-time Tracking algorithm uses color, pattern (brightness), and subject distance (depth) data to process spatial information while AI technology detects a subjects face and eye in real time. Available for both stills and movies.

Focal-plane phase-detection AF supports A-mount lenses

Phase-detection AF can operate even when an A-mount lens is attached to the 7R IV via an LA-EA3 Mount Adaptor. The 567-point focal-plane phase-detection AF system provides wide-area coverage, fast response, and high-performance tracking even if an A-mount lens is attached.

Wireless PC Remote function

Using the 7R IV alone, you can operate newly supported wireless PC Remote functions via Wi-Fi (2.4 GHz/5 GHz selectable) to remotely control camera settings or send captured images to the camera while shooting. This cable-free setting allows maximum shooting freedom in indoor and outdoor shooting sessions. Moreover, the 7R IV also provides PC Remote functions via USB 3.2 Gen 1 compatible USB Type-C port, for image data transfer at time of tether-priority shooting. Even large-sized RAW images can be transferred smoothly and checked via PC immediately.

Versatile flash compatibility

The 7R IV has a sync terminal, so non-dedicated flash units and cables with standard sync terminals can be connected for convenient synchronization with studio flash units, etc. Release time lag when shooting with flash is minimized for smooth, responsive flash photography. Continuous flash shooting at up to 10fps offers advanced capture capability. To enhance versatility further, slow sync and rear curtain sync can be selected when shooting with wireless off-camera flash.

240.8 Megapixel Pixel Shift images

The sony 7R IV supports 240.8 megapixel shooting image compositing from 16 pixel-shifted images in addition to previously available compositing from four images. Applying advanced image stabilization control, this renewed feature precisely shifts the sensor in half-pixel increments four times and in one-pixel increments four times alternately, to capture a total of 16 pixel-shifted images. These are composited by PC into one high-precision image of approx. 240.8 million pixels (19,008 x 12,672) from original data that holds the equivalent of approx. 963.2 million pixels to achieve overwhelming resolution in a single picture. Still images of architecture and art are captured in true-to-life detail, texture, color, mood, setting, and 3D-like realism, recreating hues with minimal moir or color artifacts, and even reproducing atmosphere and surroundings with breathtaking fidelity for unprecedented accuracy in real-life imagination.

Durable and weather resistant

The 7R IV brings you further enhanced body durability, with full use of lightweight, high-rigidity magnesium alloy for covers and internal frame, keeping the camera highly rigid and light. In response to pro opinions, enhanced sealing is applied to the battery cover, terminal cover and all joints in the chassis. A double-sealed sliding mechanism replaces the hinge to the media compartment lid for better moisture resistance. Routes to dust and moisture entry have been re-examined, and a cushion around the lens mount has been added to ensure reliable operation in challenging environments.

Redesigned controls for confident and comfortable operation

A new multi-selector lets you shift point of focus quickly and intuitively to avoid missing moving subjects. The surface texture is changed to enhance button response for easier and more confident operation, in reply to pro users requests. In addition, the AF-ON button is enlarged and optimized for easier access, with an adjusted click feeling and location. Furthermore, the new Exposure Compensation Dial Lock Button locks or unlocks alternately at each press and prevents accidental turning when set to lock position. These improvements enhance your concentration on shutter release to "capture the moment" instantly.

Various touch operations for operational freedom

Touch Focus enables you to simply touch the monitor screen to specify a desired subject near frame edges. Touchpad focus point control allows you to drag the focus frame to any point with a fingertip while using the viewfinder. Touch Tracking makes it easy to initiate subject tracking in stills and movies. Double-tap for a magnified view. Also, 7R IV response speed of Touchpad operation is approx. 1.5 times faster than the 7R III.

Making true-to-life high-resolution 4K movies
