Product Description
Alpha a7R IV "A" Full-Frame Mirrorless Camera Body
The a7R IV A Full-Frame Mirrorless Camera features a 60MP full-frame
back-illuminated CMOS sensor that offers a remarkable resolution and outstanding
details. The Sony Alpha a7R IV A has a powerful, high-speed BIONZ X image
processing engine that offers sharp, high-contrast images with accurate color
reproduction even in low-light conditions. It also includes a built-in 5-axis
image stabilizer for minimized vibration, Superb AF coverage, speed, and
tracking, Real-time Eye AF, up to 10 fps burst shooting for capturing decisive
moments, and much more.
61MP Full-Frame Sensor
The a7R IV features a 35mm full-frame back-illuminated CMOS image sensor
with 61MP effective pixels that deliver sharp details and accurate colors. The
back-illuminated structure and effective area-specific noise reduction
techniques combine to produce an excellent blend of low noise and high
sensitivity for enormous imaging potential.
15-Stop Dynamic Range
The Alpha 7R IV A has a 15-stop dynamic range at low sensitivities, which
results in smooth natural gradations ranging from deep shadows to highlights,
and uses algorithms from several Alpha cameras to maintain outstanding color
reproduction.
BIONZ X Processing
Sonys BIONZ X image processing engine features Advanced Detail Reproduction
Technology and Area-specific Noise Reduction. They have been tuned to maximize
the performance of a sensor. The sensor offers approximately 1.5 times more
resolution than the highly acclaimed Alpha 7R III, producing extremely fine,
realistic reproduction of textures and details.
Low Noise at High ISO
Achieve optimum image quality in just about any light, 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. Noise is effectively
reduced even at high sensitivities, maintaining outstanding image quality even
with this sensors 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 files for overall high image quality. 14-bit RAW output
is available even when shooting in silent or continuous mode.
Speed Up to 10fps with AF/AE Tracking
Thanks to the advanced mechanical shutter unit and updated image processing
algorithms, you can now shoot full 61MP resolution images at up to 10 fps 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 accuracy image detail.
4D FOCUS
The Alpha 7R IV A's new image sensor 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 operates 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 to capture fast-moving objects.
Real-Time Autofocus Tracking
Track moving subjects when shooting stills or movies, with the Real-time
Tracking that employs artificial intelligence to tenaciously track moving
subjects.
