ILCE-7RM3/B

α7R III Full-frame Mirrorless Interchangeable-Lens
Camera

Thanks to an evolutionary leap in image processing
power and eciency, the a7R III combines a high­resolution 42.4 MP back-illuminated Exmor R® CMOS
image sensor with impressive shooting speeds at up to
10 fps1 with full AF/AE tracking, as well as beautiful 4K2
HDR3 video quality, wide 15-stop4 dynamic range and
high sensitivity with noise reduction of almost a full stop4.

Key Features

Spectacular 42.4MP full-frame resolution

The 42.4MP high-resolution, back-illuminated Exmor R® CMOS sensor utilizes a gapless on-chip lens
design and AR (anti-reective) coating on the surface of the sensor’s seal glass to dramatically
improve light collection eciency. This results in high sensitivity with low-noise performance and
wide 15-stop4 dynamic range. No optical low pass lter maximizes resolution, while also having
the ability to output 14 bit RAW
Nothing less than spectacular images.

Evolutionary leap in image processing power

The a7R III features a new front-end LSI that eectively doubles* the readout speed of the image
sensor, as well as an updated BIONZ X™ processing-engine that boosts processing speed by
approximately 1.8 times compared to the a7R II. These powerful components work together to
allow the camera to shoot at faster speeds while also enabling its impressive ISO range of 100 ­32000 (expandable to ISO 50 – 102400 for still images) and massive 15-stop4 dynamic range at low
sensitivity settings. This ensures outstanding overall performance at all settings and in all shooting
conditions.

Up to 10fps1 with Silent or Mechanical Shutter

The a7R III is equipped with a rened image processing system that allows it to capture full

42.4MP images at up to 10 fps1 with continuous and accurate AF/AE (autofocus and auto
exposure) tracking for up to 76 JPEG / RAW images or 28 uncompressed RAW images11. This
high speed 10 fps mode is available with either a mechanical shutter or an electronic shutter for
completely silent shooting, adding to the immense exibility of the camera. The a7R III can also
shoot continuously at up to 8 fps1 in live view mode with minimal lag in the viewnder or LCD
screen. These high speed options ensure that fast moving subjects can be captured with extreme
accuracy and incredible image detail.

Incredible hybrid autofocus system

The upgraded focusing system of the a7R III is comprised of 399 focal-plane phase-detection
AF points that cover approximately 47% of the image area in both the horizontal and vertical
directions and 425 contrast AF points which cover approximately 68% of the image area (an
increase of 400 points compared to the a7R II). When combined, both contrast and phase
detection AF points form the hybrid AF system for wide, fast, reliable AF that locks on and stays
locked on. This advanced system delivers AF acquisition in about half the time as the a7R II in low­light conditions with tracking that is approximately 2 times more accurate as well. The acclaimed
Eye AF feature is also approximately twice as eective4, and is available when utilizing Sony’s
A-mount lenses with an adapter12.

5.5-step7, 5-axis in-body image stabilization

The 5-axis in-body SteadyShot™ image stabilization system has been ne-tuned to support high­resolution shooting capacity, resulting in the world’s highest10 compensation performance for
an image stabilization system at 5.5 step7 shutter speed advantage. Camera shake is eectively
compensated on 5 axes: pitch and yaw that have the largest overall impact on image quality;
X and Y shi that is most apparent at high magnication, and roll that can ruin night shots and
movies. Stabilization is applied to the live-view image, making it easier to frame fast-moving
subjects. Eective stabilization is provided for movies as well as stills, and for A-mount lenses
attached via a mount adapter12.

Low-vibration high-reliability shutter

format even when shooting in silent or continuous mode.

Thanks to a new shutter unit with a fast-response coreless motor and a brake system, front and
rear curtain mechanical shutter vibrations that can cause blur, is subdued to a minimum, while
allowing high-speed continuous shooting at up to 10 frames per second. The shutter is also
quiet, and has been tested for durability in excess of 500,000 shutter cycles4. Low-vibration high­reliability shutter helps to maximize 42.4 eective megapixel performance and enables 10 frame
per second shooting with high speed studio strobes.

Pixel Shi Multi Shooting

8

In a “normal” digital capture each pixel represents just one color: red, green, or blue. The
surrounding pixels are used to supply the necessary extra information required to interpolate and
reproduce the remaining two primary colors. Pixel Shi Multi Shooting8 takes advantage of the
advanced in-body image stabilization system. It precisely shis the sensor in 1-pixel increments
to capture four pixel-shied images containing a total of approximately 169.6 million pixels8
that are later composited using supplied soware running on a personal computer to achieve
overwhelming subjective resolution in a single 42.4MP image. Still images of subjects such as
architecture and art are captured with true-to-life details, texture, and color.

Secure and versatile dual SD media slots

Two SD media card slots are provided for still and movie storage (one slot for SD cards or Memory
Stick) with the lower card slot being UHS-II compatible for fast write speed. Still or movie data can
be simultaneously recorded to both cards for backup, or RAW images can be recorded to one
card while JPEG images are recorded to the other. It is also possible to record stills and movies to
dierent cards. Data can be copied between cards while in the camera, for convenient back­up. Sony SF-G series UHS-II SD cards are ideal for situations where maximum transfer speed is
required.

High Quality 4K2 HDR3 for the Video Professionals

The a7R III is exceptionally capable as a video camera, oering 4K2 (3840x2160 pixels) video
recording across the full width of the full-frame image sensor. When shooting in Super 35mm
format, the camera uses full pixel readout without pixel binning to collect 5K (15-megapixels)
of information, oversampling it to produce high quality 4K footage with exceptional detail and
depth. Both S-Log2 and S-Log3 are available for increased color grading exibility, while HLG
(Hybrid Log-Gamma)3 is included to support an Instant HDR (High Dynamic Range) workow,
allowing HDR (HLG) compatible TV’s to playback beautiful, true-to-life 4K HDR imagery. The a7R
III can also record Full HD at 120 fps at up to 100 Mbps*, allowing footage to be reviewed and
eventually edited into 4x or 5x slow motion13 video les in Full HD resolution.

The detail of 4K2, the beauty of HDR

4K2 HDR3 (High Dynamic Range) astonishes viewers with visual depth and impact that are less like
conventional movies and television – and more like real life. With the ability to reproduce images
from deep shadows to piercing highlights, 4K High Dynamic Range (HDR) is astonishing. With
Instant HDR, a rst in palm-sized cameras, the a7R III empowers you to capture High Dynamic
Range without complex post production. Hybrid Log-Gamma (HLG) recording captures HDR,
yet plays back beautifully on both HDR and conventional televisions. For added versatility, the
camera also provides S-Log3 encoding.

16-bit processing and 14-bit RAW15 output for natural gradations

Both compressed and uncompressed 14-bit RAW15 format are supported. The 14-bit digital signal
from the image sensor’s analogue to digital (AD) converter is processed in 16-bit form by the
front-end LSI and BIONZ X™ image processor before being output as 14-bit RAW data. The result is
smoother, more natural gradations that contribute to higher overall image quality. The enhanced
BIONZ X image processing LSI makes 14-bit RAW output available even when shooting in silent or
continuous mode15.

Simple connectivity to smartphones via Wi-Fi®/NFC.

Thanks to built-in Wi-Fi®, you can easily connect to a compatible iOS or Android™ smartphone or
tablet with the free PlayMemories Mobile App. From there you can control your camera, preview
and frame using your mobile device and trigger the camera shutter or movie button. Then
instantly transfer a photo or MP4 movie to your device. FTP le transfer via Wi-Fi allows convenient
Wi-Fi transfer of still image les selected via the menu display to a specied remote FTP server.
FTPS (File Transfer Protocol over SSL/TLS) is supported, allowing SSL or TLS data encryption for
maximum security. NFC™ (Near Field Communication) provides “one-touch connection”
convenience to Android™ smartphones and tablets with NFC. Simply touch devices to connect.
Setting up your mobile device is as simple as downloading a free PlayMemories Mobile app

Quad-VGA OLED Tru-Finder with 120 fps* refresh rate

The a7R III boasts a high-luminance 3,69K-dot Quad-VGA OLED Tru-Finder which reproduces the
nest details, and incorporates legendary ZEISS T* coating to greatly reduces reections, while
the double-sided aspherical element achieves 0.78x magnication with outstanding corner-to­corner clarity. A menu setting allows viewnder and monitor display quality to be set to “STD” or
“Hi”. The “Hi” mode takes advantage of the large amount of data read from the 42.4 eective
megapixel sensor to provide extra ne viewnder and monitor displays with minimal moiré
and jaggies, providing ner detail and a more natural overall view while shooting. It also has
a customizable frame rate, with options of either 60 fps or 120 fps14 to best match the action.
There’s even a uorine coating on the outermost viewnder lens that repels ngerprints, dust,
water, oil, and dirt.

3-inch 1,440K-dot tiltable LCD screen with touch AF

The tiltable 3-inch (1,440k dots) Xtra Fine LCD™ Display makes it easy to photograph over crowds,
or objects close to the ground or maybe you just want to get a dierent perspective. The screen
can swivel up approx. 107° and down approx. 41° and features a convenient touch AF function
for fast intuitive focus. The large display delivers brilliant-quality still images and movies thanks to
WhiteMagic™ technology that nearly doubles the brightness of the display through a unique
RGBW pixel structure for easier checking of the focus and image details.

Touch AF function

Focusing doesn’t get any more intuitive than this. With Touch Focus you can simply touch the
LCD screen to specify the desired focus point. Even subjects near the edges of the frame can
be instantly selected without having to reframe or manually shi the focus point. Double-tap any
point on the monitor for a magnied view of that area when focusing manually. Touch AF allows
smooth focus point changes when shooting movies too.

Enhanced Eye-AF

Eye AF automatically detects and focuses on the subject’s eye. It has been notably improved
in the a7R III, providing approximately twice as eective compared to the a7R II, even when
shooting a moving subject in continuous AF mode. Face detection has also been updated for
higher reliability when the subject is looking away from the camera, when the face is in partial
darkness, and other challenging situations.

Fast focus with A-mount lenses

The focal plane phase-detection AF system does its job even when an SSM or SAM A-mount lens
is mounted via the optional LA-EA3 mount adaptor12. 399-point focal plane phase-detection AF
provides wide-area coverage and fast response for A-mount lenses as well as E-mount types,
oering high tracking performance for an extensive lineup of lenses.

Long-lasting Z battery

The high-capacity NP-FZ100 Rechargeable Battery has approximately 2.2x the capacity of the
NP-FW50 W-series battery for more than double the stamina of the W series as used in the a7R II.
The optional VG-C3EM vertical grip houses two batteries and when you need serious stamina for
long sessions there’s the NPA-MQZ1K Multi Battery Adaptor Kit that can hold up to four batteries.
The NP-FZ100 also supports InfoLITHIUM® technology, which makes it possible to view the
remaining battery power as both a percentage display and ve step icon on the camera’s LCD
screen.
