A NEW LEVEL OF REALITY
61.0-megapixel Exmor R sensor:
The A7R IV features a 35mm full-frame back-illuminated CMOS image sensor with approximately 61.0 million effective pixels, delivering depth and dimension that were once only available in medium-format cameras. Back-illuminated structure and effective noise reduction techniques combine to deliver an extraordinary blend of low noise and high sensitivity for enormous imaging potential.
BIONZ X image processing maximizes sensor potential:
Advanced Detail Reproduction Technology and Area-specific Noise Reduction, both features of Sony's BIONZ X image processing engine, have been carefully tuned to maximize the performance of a sensor that offers approximately 1.5 times more resolution than the highly acclaimed A7R III, achieving extremely fine, realistic reproduction of textures and details. Wide dynamic range is another advantage, with approximately 15-stops available at low sensitivities for smooth, natural gradations from the deepest shadows to the brightest highlights. Portrait skin tones and the colors of nature are rendered with breathtaking realism.
|EXMOR R CMOS SENSOR
||BIONZ X IMAGE PROCESSING ENGINE
Up to ISO 32000 with undiminished quality:
A standard ISO range that extends from ISO 100 up to ISO 32000 and is expandable to ISO 50 ~ ISO 102400 for still images makes it possible to achieve optimum image quality in just about any light. Noise is effectively minimized even at high sensitivities, maintaining excellent image quality even with this sensor's high pixel count.
Optimum sharpness for any subject:
The range of sharpness settings available for the Creative Style function has been increased from ±3 to ±5. Increased sharpness can be useful for subjects that benefit from high clarity. Reduced sharpness can produce more flattering portraits.
16-bit processing and 14-bit RAW output:
Image sensor output is processed in 16-bit form by the front-end LSI and BIONZ X processor before being output as compressed or uncompressed 14-bit RAW files that have smoother, more natural gradations for higher overall image quality. 14-bit RAW output is available even when shooting in silent or continuous mode.
MAKING THE MOST OF 61.0 MEGAPIXELS
In addition to the mechanical shutter, the A7R IV has an electronic shutter that operates without moving parts for silent, vibration-free shooting. This also makes it easier to elicit maximum performance from the camera's high-resolution sensor.
Reliable low-vibration shutter:
Shutter vibration that can cause blur is reduced to a minimum, even when shooting continuous bursts at up to 10 frames per second, thanks to a new shutter unit with a fast-response coreless motor. The system also includes a brake that subdues mechanical front and rear curtain shutter vibration, and dampers that absorb mechanical shock. Low shutter vibration is critical to achieving full quality from the camera's high-resolution image sensor. The shutter is also quiet, and has been tested for durability in excess of 500,000 shutter cycles.
5-axis image stabilization:
A precision stabilization unit and gyro sensors work with refined image stabilization algorithms to achieve up to a 5.5-step shutter speed advantage that also supports the high-resolution capabilities of the 61.0-megapixel sensor. The live view image is also stabilized while shooting stills, making it easier to frame and focus when using a telephoto or macro lens. In-body image stabilization means that effective stabilization can be achieved with a wide range of lenses. 5-axis image stabilization is effective for movies as well as stills.
||5-AXIS IMAGE STABILIZATION
WHEN EVER HIGHER RESOLUTION IS NEEDED
16-image Pixel Shift Multi Shooting:
This feature takes advantage of advanced in-body image stabilization system control, capturing multiple pixel-shifted images that are later composited using a computer to achieve overwhelming resolution in a single image. In addition to 4-image composites, the A7R IV is capable of producing 16-image composites with approximately 240.8 million pixels (19008 x 12672 pixels) from data that is equivalent to approximately 963.2 million pixels. The result is photographs with detail and presence that are simply stunning. Resolution, color, and material textures are astonishingly realistic even when the image is enlarged by more than 100%.
||NORMAL SINGLE SHOT (200%)

Accurate RGB for superior color fidelity:
In 4-image composites, each of the sensor's pixels can represent the full range of red, green, and blue values simultaneously. The interpolation that is required with standard one-shot images becomes unnecessary, so the data from the sensor can be directly synthesized to recreate the final colors with minimal moiré or color artifacts. 16-image Pixel Shift Multi shots produce even more accurate RGB data using approximately four times the amount of data (240.8 million pixels) for unprecedented resolution and color reproduction accuracy. The feeling of depth is simply astonishing.
CAPTURE WITH CONFIDENCE
4D FOCUS - Wide, fast, reliable AF gets the shot:
The new image sensor in the A7R IV features 567 phase detection points in a high-density focal plane phase-detection AF system, covering approximately 99.7% of the image area vertically and 74.0% horizontally. High-density focal plane phase-detection works with 425 contrast AF points in a Fast Hybrid AF system that can handle a huge volume of data at high speed, snapping rapidly into focus with just about any subject and situation. Tracking performance has been improved too, despite the significant increase in resolution.
Reliable AF in low light:
Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-3 in the AF-S mode. The A7R IV also includes a Focus Priority mode, providing more reliable AF in low light when using smaller apertures. When shooting at a smaller aperture with large studio strobes, for example, the Focus Priority mode uses available light to focus with the aperture open right up until the instant before actual exposure, making it possible to focus on moving subjects with greater precision. All of this makes AF substantially more precise and reliable in dark scenes.
Real-time Tracking is a state-of-the-art feature that employs artificial intelligence to tenaciously track moving subjects when shooting stills or movies. Accurate focus is maintained automatically while the shutter button is half-pressed. The subject to be tracked can also be specified by touching it on the monitor when the Touch Tracking function is engaged. An advanced subject recognition algorithm uses color, pattern (brightness), and subject distance (depth) data to process spatial information in real time. If the subject is a person, AI is used to detect and keep track of the subject's eye and face in real time for extremely high tracking precision. The focus area will seamlessly change between face and eye according to the condition of the subject.
Class-leading speed and high-resolution continuous shooting with accurate AF/AE:
An advanced mechanical shutter unit and updated image processing algorithms allow continuous shooting at up to 10 fps with accurate AF/AE tracking, even with this camera's high-resolution 61.0 effective megapixel sensor. With this type of speed, you won't miss the most photogenic moments and expressions of moving subjects. It is also possible to shoot continuously at up to 8 fps in live view mode, with minimal viewfinder/monitor display lag for easy, stable framing, even with dynamic subject motion. When using the APS-C crop angle of view you have approximately 26.2 million pixels that can provide extra reach for bird photography, for example.
Up to 68 images per continuous burst:
Buffer memory has been increased by 1.5x, allowing up to 68 Extra Fine/Fine JPEG or compressed RAW images to be captured in one continuous burst. Approximately 3x more continuous images can be captured in the APS-C mode, so you can shoot continuously with confidence.
Another evolution in Real-time Eye AF:
Real-time Eye AF employs artificial intelligence to detect and process eye data in real time, and track the subject's eye with unprecedented precision. This function can be activated via an assigned custom key, or by simply pressing the AF-ON button or half-pressing the shutter button. When used with the Real-time Tracking function, tracking will continue even if the camera is temporarily unable to locate the subject's eye, so it is easier than ever to shoot dynamic portraits of moving subjects. Response when using a custom key assignment has been improved for even faster shooting.
Reliable tracking in tricky situations:
Real-time Eye AF tenaciously tracks the subject's eyes in AF-C mode, even when shooting portraits indoors, when obstacles come between the camera and subject, when the subject is not looking directly at the camera, when the subject is wearing glasses, and more.
|SUBJECT LOOKING DOWN
||INDOOR SHOT WITH DIMLY LIT FACE
||OBSTACLES OBSCURING THE FACE
Right/Left eye selection:
In addition to automatic eye selection when using Eye AF, it is also possible to manually preselect the subject's right or left eye. This can be an advantage for portraiture in which the eye to be focused on is predetermined, allowing the photographer to concentrate on composition, lighting, and other details. This function works for both stills and movies.
Real-time Eye AF animal mode tracks animal eyes:
Advanced AI-based subject recognition technology now allows fast, precise, automatic detection and tracking of animal eyes. This new capability can vastly increase success rates when photographing animals in a variety of settings or pets at home. Real-time Eye AF animal mode can be initiated either by pressing an assigned custom button or by half-pressing the shutter button.
IN THE STUDIO
Enhanced productivity for the working pro:
PC Remote (tethered) shooting, where data is directly transferred to a computer so it can be viewed on a large monitor by staff and clients, is essential for smooth, productive workflow at model and product shoots. The A7R IV offers high-speed wired and wireless tethering capability with a number of file transfer and sorting options for maximum flexibility.
Wireless tethering (PC Remote):
Wireless connectivity and PC Remote shooting let the photographer move around with fewer restrictions for a smoother, more efficient setup and workflow. The ability to connect the camera and computer via 2.4 GHz or 5 GHz Wi-Fi provides the versatility, reliability, and speed needed to transfer image data to the computer while shooting images in continuous mode. With the camera and computer connected using Sony's Imaging Edge "Remote" software application (Ver. 2.0 or later), it is easier than ever to shoot, change camera settings, and transfer and store still images. In addition to wirelessly connecting the camera directly to the computer, the connection can be made via a wireless access point for compatibility with a variety of network environments.
Fast USB connection:
A USB Type-C connector that supports fast USB 3.2 Gen 1 data transfer is provided. This makes high-speed PC Remote data transfer available while shooting for smooth handling of large image files. Efficient data handling both at the camera and computer ends of the connection results in transfer speeds approximately 2x faster than the A7R III, for smooth transfer of large uncompressed RAW image files without interrupting the flow of the session.
|WIRELESS TETHERING (PC REMOTE)
||FAST USB TYPE-C CONNECTION
PC Remote file storage options:
During PC Remote shooting, the file storage destination can be set so that images are stored in the camera as well as on the computer. This creates backups while allowing the operator to review images on the camera without having to leave the camera position. This feature has been refined in the A7R IV, so that it is now possible to change the storage destination from either the camera or a computer running the Imaging Edge application while shooting. Another option is to transfer only JPEG files to the computer rather than both the JPEG and RAW files, reducing data volume and allowing transferred images to be checked almost immediately. You can even choose to transfer the original JPEGs or compact 2-megapixel versions for maximum speed.
Studio lighting support:
A standard sync terminal is provided for convenient synchronization with studio flash units and other external lighting equipment. Minimal release time lag contributes to smooth, responsive flash photography. Continuous flash shooting at up to 10 fps offers advanced capture capability. Slow sync and rear curtain sync can be selected when shooting with wireless off-camera flash for even further enhanced versatility.
Wireless remote commander support:
New RMT-P1BT Wireless Remote Commander (sold separately) using Bluetooth technology is supported. Bluetooth communication is unaffected by obstacles or ambient light, providing greater flexibility and reliability for a variety of shooting situations. Wireless shutter triggering can also reduce vibration and blur.
||RMT-P1BT WIRELESS REMOTE COMMANDER (OPTIONAL)
Imaging Edge applications (Remote/Viewer/Edit):
Elevate your photography with Imaging Edge desktop applications. Use "Remote" to control and monitor shooting live on your PC screen; "Viewer" to quickly preview, rate, and select photos from large image libraries; and "Edit" to develop RAW data into high-quality photos for delivery.

Full pixel readout without binning in Super 35mm mode for high-resolution 4K movies:
Full frame and Super 35mm formats can be selected for 4K movie recording. Full pixel readout in the Super 35mm mode (approx. APS-C 16:9), without the need for pixel binning, makes it possible to condense approximately 2.4 times the amount of data required for 4K movies (QFHD: 3840 x 2160), resulting in high-resolution, high-detail 4K with minimal moiré and jaggies. Furthermore, the advanced image processing system delivers more accurate skin tones as well as smoother highlight gradations. 4K recording employs the XAVC S format at bit rates as high as 100 Mbps.
Fast Hybrid AF for movies:
A refined Fast Hybrid AF system achieves faster, smoother, more stable autofocus during movie recording. Consistent, stable tracking is maintained even if an object temporarily moves in front of the main subject, or a small aperture must be used. This greatly reduces the need for manual focus adjustments when the camera is used on a gimbal, for run-and gun projects, or in other one-operator shooting situations.
Real-time Eye AF for movies:
Human eyes can now be automatically identified and precisely tracked while shooting movies, so the operator can concentrate on the content rather than focus. The same Touch Tracking functionality that is provided for stills is also available for movie shooting, easily initiating Real-time Eye AF tracking on a specified eye. Right/left eye selection is available for movies too.
Touch Tracking for movies:
Touch Tracking is also a boon for movie recording. Touch the subject to be tracked on the monitor, and the Real-time Tracking function will then process color, pattern (brightness), distance (depth), and face information to precisely and smoothly track the selected subject at the specified sensitivity and speed. It is also possible to half-press the shutter button or press the AF ON button while shooting to achieve fast focus (AF-S). This can be an advantage for weddings or documentaries, where there is only one chance to capture a scene. In such cases the focus area selected in advance is applied.
Multi Interface Shoe with digital audio interface:
On the A7R IV, Sony's Multi Interface Shoe features a built-in digital audio interface that allows direct connection of the new digital ECM-B1M Shotgun Microphone or XLR-K3M XLR Adaptor Kit (both sold separately) for clear, low-noise audio recording. Like other MI shoe accessories, no cables or batteries are required, providing unrestrained freedom for Alpha system moviemaking.
|TOUCH TRACKING FOR MOVIES
||MULTI-INTERFACE SHOE WITH DIGIAL AUDIO INTERFACE
Assignable XAVC S file name prefixes:
Prefixes can be assigned to movie files as well as still images via the menus. This can make it easy to identify which camera a file was recorded on when using multiple cameras. When multiple memory cards are used, the file numbering method can be set to "sequential" to prevent duplicate file numbers.
Instant HDR workflow:
An HLG (Hybrid Log-Gamma) picture profile that supports an instant HDR workflow is provided. Recorded movies played back on an HDR (HLG) compatible TV will appear true-to-life, with no blocked shadows or blown highlights, and without the need for color grading.
S-Log3 for wide 14-stop dynamic range:
In addition to S-Log2, S-Log3 is available for better gradation from shadows to mid-tones (18% gray), and a dynamic range of up to 14 stops. Both of these S-Log gamma curves provide extra margin for post processing, making it easier to achieve wide dynamic range.
Time-lapse movies document the passing of time:
In-camera interval shooting is now possible without the need for additional apps. Depending on the number of pixels, interval sequences can be converted to 4K time-lapse movies. A variable-speed preview function lets you see how the finished movie will look right on the camera monitor.
Slow & Quick Motion:
Frame rates from 1 fps to 120 (NTSC)/100 (PAL) fps can be selected in eight steps for up to 60x quick motion and 5x slow motion, recordable at up to 50 Mbps with full-HD quality.
4K movies and lower-resolution proxy movies can be recorded simultaneously. The smaller proxy files are ideal for quick previewing.
Other movie features:
Picture profiles, Clean HDMI, Time Code/User Bit, REC control, Gamma Display Assist, a Zebra function, and other details provide comprehensive support for advanced video workflows.
SMALL, LIGHT, RUGGED, AND READY FOR WORK
Enhanced dust and moisture resistance:
Dust and moisture resistance have been significantly improved with refinements throughout the body. Additional sealing is provided at all body seams as well as the battery compartment cover, and the media slot now has a double sliding cover rather than the previous hinged cover to keep water out. A redesigned lens lock button and additional cushioning around the mount further contribute to outstanding reliability in challenging outdoor conditions. Importantly, all of this has been accomplished in a body that is about the same size as the A7R III.
Designed and built for durability:
Body durability has been enhanced by the use of a lightweight, high-rigidity magnesium alloy for the top cover, front cover, internal frame, and rear cover. Attachment points and rigidity at the lens mount are ample too, providing the strength needed for heavy lenses.
|DUST AND MOISTURE RESISTANCE
||MAGNESIUM ALLOY BODY
Dual UHS-II slots:
The A7R IV has two media slots that are both compatible with UHS-I and UHS-II SD cards for higher overall capacity and faster read/write speeds. Data can be simultaneously recorded to both cards for backup, RAW/JPEG and stills/ movies can be recorded to different cards, or recording can be automatically switched to the second card when the first becomes full.
To minimize stress when shooting for long periods of time and/or with long telephoto lenses, the grip area has been redesigned for greater comfort and surer hold. Ample room is provided for the little finger, and overhang in the middle finger area has been increased.

REFINED FOCUS CONTROL BOOSTS PRODUCTIVITY
Press the AF-ON button to activate autofocus when shooting stills or movies. This makes it possible to release the shutter instantly to capture fleeting moments without having to go through the normal half-press focus sequence. The dimensions, feel, and location of the AF-ON button have been revised for smooth, intuitive control.
The multi-selector provides a fast, efficient way to shift focus points. Simply press the up, down, left, or right button when using the Zone, Flexible Spot, or Expand Flexible Spot focus area mode. A redesigned multi-selector shape and textured surface provide improved grip. Response in all eight directions has also been improved.
3.0 type 1.44 million-dot tilting LCD monitor:
This 3.0 type LCD touch screen with 1.44 million dots features high resolution for detailed viewing. WhiteMagic technology is included to ensure that LCD viewing is bright and clear even in outdoor conditions. The monitor tilts upwards by a maximum of 107°, and downwards by a maximum of 41° for flexible hold and framing.
Simply touch the monitor screen to specify the desired focus point for stills or movies. Even subjects near the frame edges can be instantly selected without having to reframe or manually shift the focus point. Double-tap any point for a magnified view of that area when focusing manually.
Exposure compensation dial lock:
An exposure dial lock release button newly located at the center of the exposure compensation dial can be locked to prevent accidental, unwanted changes, or unlocked to allow rapid adjustments in varying light conditions.
The monitor Touch Pad function allows the focus frame to be dragged to any desired point with a fingertip while viewing through the viewfinder. Relative and absolute modes are available, and nine area patterns provide easy operation when viewing with either eye, and when positioning with either hand. Response is approximately 1.5x faster than the A7R III.
Switch Vertical and Horizontal AF Area:
Separate or identical focus areas and points can be used for horizontal and vertical camera orientations. The ability to use separate focus areas and points reduces the need to readjust focus when shooting portraits or any subject that requires frequent camera orientation changes.
AF Tracking Sensitivity:
The sensitivity with which autofocus will follow subjects that move outside the focus area can be adjusted in 5 steps when shooting stills. Higher sensitivity is best for subjects at varying distances, while lower sensitivities can keep focus on a subject that is briefly obscured by other objects.
Focus area circulation:
A new setting allows the focus area to be circulated through the upper, lower, left, and right edges of the frame. This makes it easy to select an appropriate focus area for sports or other situations where the subject frequently moves from one edge to the other.
Selectable focus frame color:
The focus frame color can be set to white or red. Red can improve visibility in situations where subject and focus frame color contrast is low and it is difficult to make out the focus area against the subject.
The detection accuracy of the focus peaking function has been improved, and a blue peaking color has been added to the existing red, yellow, and white selections. The new blue peaking color can provide improved visibility with warm-colored subjects.
CUSTOM FUNCTIONS KEEP CREATIVITY FLOWING
Custom function assignments can now be made to the front/rear dials and the control wheel. By assigning frequently used functions to these dials, they become instantly available for temporary use while a custom button is held. Three sets of custom functions can be assigned for even further versatility.
AF Area Registration:
Frequently used focus point settings can be memorized and instantly recalled via custom button assignments. Focus area mode settings can also be memorized and recalled as required for fast, convenient operation.
Recall Custom Setting During Hold:
Memorized settings (exposure, focus settings, AF tracking sensitivity, drive mode, etc.) can be assigned to custom buttons for temporary recall while the button is held. This is a great way to quickly make temporary setting changes for varying shooting situations.
Flexible front/rear dial and release button control:
The control direction of the front and rear dials can be set via the menus. It is also possible to assign the large, accessible shutter button to start and stop movie recording, rather than using the MOVIE button.
Expanded camera setting registration:
The number of camera settings that can be saved to and read from memory card via the Save/Load Settings function has been greatly increased. Saved settings can be loaded into any camera body of the same type. Up to 10 combinations of settings can be saved to one memory card. It is now also possible to save settings to the Imaging Edge Mobile application (Ver. 7.2 or later), from where they can be transferred to a separate body of the same type.
Smooth menu access:
The My Menu feature allows up to 30 items to be registered to a user menu for instant recall. Normal menu navigation is easier too: the front dial or Fn button selects menu tabs, the rear dial selects sub-tabs, and the control wheel selects individual menu items. Separate Fn button functions can be assigned for the still and movie modes. Illustrated custom menu items make it easy to identify the functions assigned to each control.
|EXPANDED CAMERA SETTING REGISTRATION
||SMOOTH MENU ACCESS
FLEXIBLE EXPOSURE AND WHITE BALANCE CONTROL
Auto white balance can now be locked or unlocked on the fly while shooting, to set white balance to match one of several light sources in mixed lighting situations. In an environment with mixed artificial and natural window light, for example, you might want to ensure that white balance matches the artificial indoor light.
Expanded custom white balance control:
Rather than being fixed at the center of the frame, the measurement area for custom white balance settings can be moved around as required so custom white balance can be set after the image has been composed. Custom white balance acquisition and positioning can also be controlled from the computer during PC Remote shooting.
Priority Set in AWB:
When white balance is set to Auto and incandescent lamps or similar are the light source, the color tone priority can be set to Standard, Ambience, or White. Ambience priority produces a warm tone, while white priority reproduces accurate whites.
1200-segment live-view exposure analysis:
The live view image is divided into 1,200 segments for detailed analysis of subject color and lighting. The use of focus information to ensure consistent AE control is another innovation that can reduce variations in image brightness in varying situations.
Comprehensive metering modes:
In addition to the Multi, Center, and Spot metering modes, a Highlight mode detects the brightest area in the frame to avoid blown highlights, and an Entire Screen Average mode can provide stable auto exposure through composition changes.
Versatile spot metering:
When the Focus Area parameter is set to Flexible Spot or Expand Flexible Spot the metering spot location can be linked to the focus area so that the optimum metering point is maintained automatically. Two spot sizes are available to match a wide range of subjects.
Exposure standard adjustment:
The standard exposure value can be adjusted from -1 to +1 stop in 1/6 stop increments. This setting can be made separately for each metering mode.
Flicker from fluorescent lights and other artificial lighting can ruin still images if it and the shutter timing are out of sync. The A7R IV automatically detects flicker and adjusts shutter timing to eliminate exposure and color variations, even when shooting continuously at up to 10 fps with AF and AE tracking.
OTHER FILE MANAGEMENT AND SHOOTING FUNCTIONS
10/100 image review jump:
In addition to scrolling through recorded images one at a time, a new Image Jump setting make it possible to skip ahead by 10 or 100 frames, making it faster and easier to locate a desired image.
Display continuous shooting group:
Images shot in continuous mode can be reviewed as groups, and the play index display has been significantly improved. Continuous groups can be deleted or protected in one quick operation to save time on location.
Ratings and protect functions:
Ratings of from 1 to 5 stars can be applied to still images right from the camera controls. The rating and protect functions can be set via assigned custom buttons while viewing the review playback display on location or while traveling to save time.

||RATINGS AND PROTECT FUNCTIONS
New 4:3 and 1:1 aspect ratios:
In addition to the previously available 3:2 and 16:9 aspect ratios, it is now also possible to select 4:3 and 1:1 aspect ratios. The availability of these extra in-camera aspect ratios facilitates delivery in a correspondingly wider range of formats, reducing the need for post-shoot cropping and allowing for speedier delivery.
FTP background transfer:
This function allows convenient Wi-Fi transfer of still image files to a specified remote FTP server. FTPS (File Transfer Protocol over SSL/TLS) is supported, allowing SSL or TLS data encryption for maximum security. Background FTP file transfer via Wi-Fi is now possible while shooting or reviewing still images. Additional improvements include the ability to specify files for transfer, the ability to specify a file format (JPEG/RAW), and more. The number of FTP servers that can be pre-registered has been increased from three to nine, and it is possible to set up folder configurations on the destination FTP server. 5 GHz band communication has also been added for more stable, reliable data transfer. These and other refinements contribute to improved workflow on location.
Smart mobile device pairing:
Install the Imaging Edge Mobile app on your mobile device via Wi-Fi, then touch the device to the camera to connect. Pair the devices using QR code, or use NFCTM on Android devices. Imaging Edge Mobile can be used to acquire location data, link location data to still images, and correct camera date/time and location settings.
Smartphone file transfer while camera power is off:
It is now possible to transfer files from an SD card in the camera via Wi-Fi even if the camera power is OFF. Images to be transferred are selected via the Imaging Edge Mobile application installed on a on a mobile device. Movie files can also be transferred in this way.
