SONY A7R III
OVERVIEW
Proving
that speed, resolution, and video capabilities can all coexist, the a7R III
Mirrorless Camera from Sony is a versatile, high-performance camera
characterized by not only its resolution, but by its multimedia versatility.
Revolving around a full-frame 42.4MP Exmor R BSI CMOS sensor and updated BIONZ
X image processor, the a7R III affords an impressive 10 fps continuous shooting
rate along with improved autofocus performance for faster, more reliable
subject tracking along with wide frame coverage. This updated Fast Hybrid AF
System employs a combination of 399 phase-detection points and 425
contrast-detection areas for quicker acquirement of focus in a variety of
lighting conditions, and also maintains focus on subjects more effectively. In
addition to speed and AF, the processing improvements also help to realize
greater image clarity throughout the sensitivity range from ISO 100-32000, which
can further be expanded to ISO 50-102400. Video recording capabilities have
also been extended for enhanced quality when recording UHD 4K video with the
full width of the full-frame sensor, or when using a Super35 area and 5K
oversampling to minimize moiré and aliasing. Additionally, benefitting both
stills and video operation, the a7R III retains the 5-axis SteadyShot INSIDE
sensor-shift image stabilization, which is now effective to minimize the
appearance of camera shake by up to 5.5 stops.
In
addition to imaging updates, the a7R III also sports a revised body design,
which includes a 3.69m-dot Tru-Finder OLED electronic viewfinder for bright,
clear, and realistic eye-level monitoring. A rear 3.0" 1.44m-dot tilting
touchscreen LCD is also available for intuitive settings control and to better
support working from high and low angles. For greater shooting flexibility,
dual SD memory card slots are now featured, and a larger NP-FZ100 battery is
also employed to achieve up to approximately 530 shots per charge when using
the viewfinder. Suiting the camera's use in trying conditions, the magnesium
alloy chassis and extensive weather-sealing also render the a7R III dust- and
moisture-resistance
Featuring
a back-illuminated design, the full-frame 42.4-megapixel Exmor R CMOS sensor
works with the BIONZ X image processor to offer high-resolution stills and
video while minimizing noise and improving speed. This sensor structure works
with gapless on-chip lens design and an anti-reflection coating, as well as eliminating
the optical low-pass filter, to improve light collection and enhance detail
An
evolved 4D FOCUS system now employs a combination of 399 phase-detection
points, which cover approximately 68% of the frame, along with 425
contrast-detection areas for reliable and quick autofocus and subject tracking
performance. This Fast Hybrid AF System now achieves twice the focusing speed
and more reliable tracking compared to previous a7R models, as well as improved
low-light focusing response down to -3 EV. The use of phase-detection points
also enables the use of A-mount lenses via the optional LA-EA3 or LA-EA1 lens
mount adapters with full continuous AF/AE tracking compatibility.
Internal
recording of UHD 4K movies is possible in multiple frame rates up to 30 fps
and, based on the Super35mm recording area and effective 5K resolution,
oversampling renders greater detail and full pixel readout is possible, that is
void of pixel binning, for higher quality imagery with reduced moiré and
aliasing. Full-frame 4K recording has also been dramatically improved for
improved quality when working at mid to high sensitivities to permit full use
of the entire sensor width. Full HD 1080p recording is also supported in frame
rates up to 120 fps, and both resolutions utilize the 100 Mbps XAVC S format
contained within an MP4 wrapper with 4:2:0 sampling. The high-speed, 120 fps
recording also enables 4x and 5x slow-motion movie recording with the frame
rate set to either 30p or 24p. In addition to high-resolution internal recording,
uncompressed HDMI output also enables the use of an optional external recorder
for clean 4K recording with 4:2:2 sampling.
