SONY α7R IV 35 mm Full-Frame Camera with 61.0 MP

Reaching the peak of resolution: 61.0 MP12 full-frame CMOS sensor
Sony’s newly developed 35 mm full-frame back-illuminated CMOS sensor with 61.0 megapixels12 enables the full-frame mirrorless α7R IV to attain expressive prowess once expected only in conventional medium-format cameras. Thanks to this mirrorless design, absence of mechanical mirror shock can maximize resolution without negative effect on image quality. The α7R IV realizes the level of image quality that surpasses the expectation for conventional full-frame cameras especially in the low- to mid-sensitivity range. Sony’s proprietary technology achieves superb high resolution while assuring low noise and high sensitivity.

The enhanced image processing engine makes the most of the CMOS sensor
To match the excellence of the new image sensor, the high-speed BIONZ X image processing engine is also further enhanced to faithfully reproduce details and reduce noise significantly. Noise that tends to occur due to heightened pixel count is minimized for high image quality, especially in the standard ISO sensitivity range up to ISO 32000. 13 Wide 15-stop dynamic range14 at low ISO sensitivity (for stills) delivers smoother reproduction of gradations from shadow to highlight. Moreover, the α7R IV’s inherited color reproduction in still pictures — acclaimed in the latest α series — captures skin color in portraits and vivid color of flowers for natural α7R IV depiction.

Features maximizing superb 61.0 MP12 resolution
The α7R IV’s extremely high image 61.0-megapixel resolution performance is maximized by other α7R IV advantages, one of which is 5-axis optical in-body image stabilization with optimized algorithms to achieve up to a 5.5-stop15 shutter speed advantage. Another outstanding feature is the electronic shutter allowing silent, vibration-free shooting. Additionally, the α7R IV incorporates an internal damper structure to absorb the impact of shutter motion for minimum shutter vibration. Many features in the α7R IV serve for realizing sharply resolved imaging.

5.76-million-dot UXGA OLED Tru-Finder
Newly featured in the α7R 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 α7R III. "High Display Quality" mode draws on the effective 61.0 MP (approx.) image sensor to suppress moiré and jaggies for highly precise and natural images on the viewfinder; 120/100fps18 of "High" finder frame rate mode shows smoother motion, so it’s 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.

Wide, fast, and steadfast AF evolution
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 α7R IV’s 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-319. 567-point phase-detection AF and 425-point contrast-detection AF provide wider image area coverage20 of 99.7% height and 74.0% width. In addition, this remarkable AF system provides as rapid a response as α7R III, despite mass data handling due to the extremely high-resolution CMOS sensor, even in dim shooting venues.

14-bit RAW output for natural gradations
The α7R IV supports compressed and uncompressed 14-bit RAW output for smoother, more natural gradations that contribute to higher overall image quality. Taking advantage of even higher 16-bit processing in the imaging engine, front-end LSI and the enhanced BIONZ X image processor make 14-bit RAW16 output available even when shooting in silent or continuous mode17.

Up to 68 images in continuous shooting
Professional photographers need to achieve consistent shooting without interruption. With 1.5x greater buffer memory, system speed, and UHS-II support, the α7R IV can capture up to approx. 68 images22 in a continuous burst at 10fps23. With APS-C shooting mode, approximately three times more photos can be shot than with full-frame shooting mode. Fn menu/menu display access, setting changes, and review playback can occur during data writing. A countdown of the number of still images remaining to be written to memory is on display during playback.

Anti-flicker shooting 24
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.
Exceptional high-speed 10fps burst shooting with AF/AE tracking
Despite a high resolution of 61.0 MP12, an ingenious algorithm enables efficient processing for high-speed continuous shooting of up to 10fps21 with AF/AE tracking through a mechanical shutter. It is also possible to shoot continuously at up to 8fps in live-view mode, with minimal display time lag for capturing fast-moving subjects. After a full-frame image is cropped down to APS-C size or if APS-C shooting mode is chosen, you can still get 26.2 MP high-resolution images. This is a great advantage for wild animal photographers who rely on cropping after capturing images of quickly moving animals/birds from afar.

Enhanced Real-time Eye AF (human eye) delivers more successful portraiture
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.

Shooting for more professional lengths
The α7R IV employs the large-capacity NP-FZ100 battery just like α7R III. Due to a more energy-efficient circuit design, the α7R IV matches α7R III usage level longevity, despite the higher resolution of the α7R 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.

Dual media slots, both supporting UHS-II
The α7R 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.

Focal-plane phase-detection AF supports A-mount lenses27
Phase-detection AF can operate even when an A-mount lens is attached to the α7R 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.

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 α7R 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 subject’s face and eye in real time. Available for both stills and movies.
Real-time Eye AF for Animals reliably tracks wild animals and pets25
Advanced AI-based subject recognition in Sony’s Real-time Eye AF includes a new algorithm supporting animal tracking for fast, precise, automatic detection and tracking of an animal’s 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. 26 All AF-C, AF-S, and AF-A focus modes are supported.

Wireless PC Remote function
Using the α7R IV alone, you can operate newly supported wireless PC Remote functions via Wi-Fi (2.4 GHz/5 GHz selectable28) 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 α7R 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.

Pixel Shift Multi Shooting31 newly supports compositing a picture from 16 pixel-shifted images
A different dimension of resolution opens with Pixel Shift Multi Shooting. The α7R IV now supports 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 PC31 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.32 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 moiré or color artifacts, and even reproducing atmosphere and surroundings with breathtaking fidelity for unprecedented accuracy in real-life imagination.

Versatile flash compatibility
The α7R 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.29 To enhance versatility further, slow sync and rear curtain sync can be selected when shooting with wireless off-camera flash.30

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.

Reliable durability and weather resistance33 in tough situations
The α7R 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.33 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.

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 Tracking34 makes it easy to initiate subject tracking in stills and movies. Double-tap for a magnified view. Also, α7R IV response speed of Touchpad operation is approx. 1.5 times faster than the α7R III.

Increased Fast Hybrid AF speed and precision for smoother, more stable movie AF
Faster, more precise Fast Hybrid AF achieves smoother, more stable autofocus in movie recording. This greatly reduces the need for focus operation when the camera is used on a gimbal or in assistance-free movie shooting. A new Touch Tracking function is also available in movie recording, allowing you to simply touch an aimed subject on the monitor to initiate tracking. Swift AF-S operation is activated when the shutter button is pressed halfway (or AF-ON button is pressed), for simplifying movie-making in "must succeed" situations including weddings and documentaries.

Making true-to-life high-resolution 4K movies 35
For high-resolution 4K movies with great detail but minimal moiré and jaggies, Super 35 mm mode36 condenses approximately 2.4 times37the data required for 4K movies (QFHD: 3840 x 2160). Advanced α7R IV processing records 4K movies with enhanced reproduction of skin color and smoother gradations. In addition to S-Log3 and S-Log2 gamma curves, the α7R IV offers HLG (Hybrid Log-Gamma)38 picture profile for instant HDR workflow, supporting a wide range of HDR movie production needs. The α7R IV incorporates XAVC S recording format for 4K35 and enables high-quality images at high bitrates of up to 100 Mbps. [1] High flexibility to fine-tune images as desired (Color grading required) [2] Instant and high-quality image (Color grading not required)

Smart collaboration with mobile devices and accessories
Even after the camera power is off, still and movie files stored on an SD memory card inserted in the camera can be transferred via Wi-Fi connection if you set it up in advance.40You can operate the Imaging Edge Mobile app41 installed on your mobile that is paired with the camera to select necessary images.
