Alpha 7R IV Full-frame Mirrorless Interchangeable­Lens Camera

Thanks to an evolutionary leap in image processing
power and eciency, the Alpha 7R IV combines world’s
rst1 high-resolution 61MP2 back-illuminated Exmor R®
CMOS image sensor with impressive shooting speeds at
up to 10 fps4 with full AF/AE tracking, as well as beautiful
4K8 HDR video, wide 15-stop3 dynamic range and high
sensitivity with area specic noise reduction.

Key Features

World’s rst1 61MP2 pixels full-frame sensor

The Alpha 7R IV features the world’s rst1 35mm full-frame back-illuminated CMOS image sensor
with 61MP2 eective pixels, delivering depth and dimension that was once only available in
medium-format cameras. The back-illuminated structure and eective area specic noise
reduction techniques combine to deliver an extraordinary blend of low noise and high sensitivity
for enormous imaging potential.

15-stop3 dynamic range

The Alpha 7R IV boasts an impressive 15-stop3 dynamic range at low sensitivities, resulting in
smooth natural gradations ranging from deep shadows to highlights, and utilizes algorithms from
many of the latest Alpha™ cameras to maintain outstanding color reproduction.

BIONZ X processing maximizes sensor potential

Advanced Detail Reproduction Technology and Area-specic Noise Reduction - both features
of Sony’s BIONZ X image processing engine - have been carefully tuned to maximize the
performance of a sensor that oers approximately 1.5 times more resolution than the highly
acclaimed Alpha 7R III, achieving extremely ne, realistic reproduction of textures and details.

Low noise at High ISO

A standard ISO range that extends from ISO 100 up to ISO 32000 with undiminished quality is
expandable to ISO 50 to ISO 102400 for still images, make it possible to achieve optimum image
quality in just about any light. Noise is eectively minimized even at high sensitivities, maintaining
excellent image quality even with this sensor’s high pixel count.

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 image
processing engine before being output as compressed or uncompressed 14-bit RAW les that
have smoother, more natural gradations for higher overall image quality. 14-bit RAW output is
available even when shooting in silent or continuous mode11.

Serious speed up to 10fps4 with AF/AE tracking

An advanced mechanical shutter unit and updated image processing algorithms allow the
innovative new full-frame Alpha 7R IV to shoot full 61MP2 resolution images at up to 10 fps4 with
continuous and accurate autofocus and auto exposure (AF/AE) tracking for up to approximately
seven seconds in JPEG and RAW, and approx. three times as long in 26.2MPii APS-C crop mode.
These high-speed options ensure that fast moving subjects can be captured with extreme
accuracy and incredible image detail.

4D FOCUS – Wide, fast, reliable AF gets the shot

The new image sensor in the Alpha 7R IV features 567 phase detection points in a high­density 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 signicant increase in resolution.

Real-time Autofocus Tracking

5

Real-time Tracking5 is a state-of-the-art feature that employs articial 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 specied 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.

Real-time Eye AF

Real-time Eye AF employs articial 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. In addition to automatic eye selection when using Eye AF, it is also possible to
manually preselect the subject’s right or le eye5.

Real-time Eye AF for animals

6

Advanced AI-based subject recognition technology now allows fast, precise, automatic
detection and tracking of animal eyes6. 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.

Real-time Eye AF for movies

5

The Alpha 7R IV debuts Real-time Eye AF for movie shooting5, a rst in any of Sony’s cameras.
When activated, human eyes are automatically identied and precisely tracked with high
precision and reliability, allowing the shooter to focus on the content itself as opposed to what
is in focus or not. 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 specied eye. Right/le eye
selection is available for movies too.

Reliable low-vibration shutter

The shutter unit assembly has been carefully re-designed to reduce even the slightest movement
that may cause blur, which is critical with high resolution sensors. 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.

Silent shooting

In addition to the mechanical shutter, the Alpha 7R IV has an electronic shutter12 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.

5-axis image stabilization

A precision stabilization unit and gyro sensors work with rened image stabilization algorithms
to achieve up to a 5.5-step
capabilities of the 61-megapixel sensor. Camera shake is eectively compensated on 5 axes:
pitch and yaw, X and Y shi and roll. 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 eective stabilization can be achieved with a wide range of lenses.
5-axis image stabilization is eective for movies as well as stills.

shutter speed advantage that also supports the high-resolution

5.76 million-dot2 UXGA OLED Tru-Finder

The Alpha 7R IV boasts a 5.76 million dot UXGA OLED Tru-nder EVF - Sony’s highest resolution
viewnder ever - at about 1.6x the resolution of the EVF in the Alpha 7R III. This new viewnder
provides an extremely accurate, true-to-life depiction of the scene being framed. The display
quality can be set to ‘Standard’ or ‘High’ mode, and to either 60 fps or 120 fps refresh rate that
provides a smooth viewnder image with minimum display motion blur when shooting moving
subjects. The eyepiece window is uorine coated to repel ngerprints and grime, and make it
easier to clean.

16-image Pixel Shi Multi Shooting

7

When even higher resolution is needed, Pixel Shi Multi Shooting7 takes advantage of the
advanced in-body image stabilization system to capture multiple pixel-shied images that are
later composited using Sony’s “Imaging Edge™” desktop application to achieve overwhelming
resolution in a single image. In addition to 4-image composites, the Alpha 7R 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% and ideal for photographing
architecture, art or any other still life subject.

Record reality in spectacular 4K

8

In addition to its impressive still image capabilities, the new Alpha 7R IV performs exceptionally
well as a serious lmmaking tool, oering 4K (3840x2160 pixels) video8 recording across the full
width of the image sensor, and full pixel readout without pixel binning in Super 35mm mode9. This
ensures high quality 4K footage with exceptional detail and depth. S-Log 2 and S-Log 3 are also
available to maximize color grading exibility, with S-Log 3 oering a total of 14-stops of dynamic
range. HLG (Hybrid Log-Gamma) is available on the Alpha 7R IV as well to support an Instant
HDR workow.

Touch Tracking for movies

Touch Tracking is benecial 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
specied 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.

Wireless tethering (PC Remote for Professional Workow

Wireless connectivity and PC Remote shooting let the photographer move around with fewer
restrictions for a smoother, more ecient setup and workow. The ability to connect the camera
and computer via 2.4 GHz or 5 GHz Wi-Fi15 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” soware 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.

Super speed USB Type-C™

In addition to high speed Wi-Fi® and wireless PC connectivity15, the Alpha 7R IV is equipped with
a SuperSpeed USB (USB 3.2 Gen 1) USB Type-C™ connector that supports extremely fast wired
data transmission, with almost doubled data transfer speed achieved in combination with Sony’s
Imaging Edge soware (compared to the Alpha 7R III), plus FTP data transfer with background
transfer capability, allowing images to be sent to a specied FTP remote server while the
photographer is still shooting or reviewing images.

Imaging Edge desktop applications

To support an ecient, high speed, connected professional workow, Sony has announced
version 2.0 of its “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. Get the best
from Sony RAW les, and manage your productions more eciently. The Pixel Shi Multi Shooting
feature can also be used while the camera and PC are tethered, and the pixel-shied images
can be immediately composited and viewed. To maximize convenience in image transfer, when
utilizing the latest version of Sony’s Imaging Edge Mobile™ application, the camera can now
transfer images to a connected smartphone even if the camera’s power is set to OFF. Refer to

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 Alpha 7R 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. In addition, 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 nger, and overhang in the middle nger area has been increased.

Dual UHS-II slots

The Alpha 7R 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 dierent cards, or
recording can be automatically switched to the second card when the rst becomes full.

Extended endurance

Sony’s high-capacity Z batteries and circuitry designed for low power consumption make it
possible to shoot up to 670 still images when using the LCD monitor or 530 images when using
the viewnder on a single charge, despite substantial increases in sensor and EVF resolution. For
even more uninterrupted operating time, the optional VG-C4EM Vertical Grip holds two NP-FZ100
batteries. The camera can also be powered from an external mobile battery via its USB Type-C™
and Multi/Micro USB connectors.

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 dicult to make out the focus area against
the subject. The focus frame will appear in magenta if focus cannot be acquired when the
shutter button is pressed.
