Key Features
World’s rst
1
61MP
2
pixels full-frame sensor
The Alpha 7R IV features the world’s rst
1
35mm full-frame back-illuminated CMOS image sensor
with 61MP
2
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-stop
3
dynamic range
The Alpha 7R IV boasts an impressive 15-stop
3
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 mode

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 61MP
2
resolution images at up to 10 fps
4
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 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 signicant increase in resolution.
