Distinguished
by its updated sensor design, the Alpha a7 III Mirrorless Digital
Camera from Sony is a
well-rounded camera suitable for both photo and video applications in a variety
of working situations. Refined for improved speed and low-light performance,
the full-frame 24.2MP Exmor R BSI CMOS sensor and BIONZ X image processor pair
to realize an impressive 10 fps continuous shooting rate and improved autofocus
performance for faster, more reliable subject tracking along with wide frame
coverage. This updated Fast Hybrid AF System employs a combination of 693
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 and reduced noise
throughout the sensitivity range from ISO 100-51200, which can further be
expanded to ISO 50-204800. Video recording capabilities have also been extended
for enhanced quality when recording UHD 4K video with the full width of the
full-frame sensor to minimize moiré and aliasing. Additionally, benefitting
both stills and video operation, the a7 III utilizes a 5-axis SteadyShot INSIDE
sensor-shift image stabilization, which is now effective to minimize the
appearance of camera shake by up to 5 stops.
Beyond just updates to
the imaging system, the a7 III's body design has also been revised to include a
rear 3.0" 922k-dot touchscreen LCD, which has a tilting design to better support
working from high and low angles. A 2.36m-dot Tru-Finder OLED EVF is also
featured for bright and clear eye-level monitoring. 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 710 shots per charge.
Suiting the camera's use in trying conditions, the magnesium-alloy chassis and
weather-sealing also render the a7 III dust- and moisture-resistant.
24.2MP Exmor R BSI CMOS Sensor and BIONZ X Image Processor
Featuring a back-illuminated design, the
full-frame 24.2-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. Also, the copper wiring
layer dramatically improves data transmission speed for creating 14-bit,
high-resolution stills with a native sensitivity range from ISO 100-51200,
which can be further expanded to ISO 50-204800. Also, it enables internal UHD
4K video recording with a wide dynamic range using the full width of the
full-frame sensor. The BIONZ X processor also works in conjunction with a
high-speed front-end LSI to realize faster processing times along with the
ability to capture an impressive 15-stop dynamic range at low sensitivity
values.
The sensor and processor combination also avails fast continuous shooting at up
to 10 fps at full resolution, for up to 177 consecutive frames, and with
full-time AF/AE when working with either a mechanical shutter or an electronic
shutter. If shooting in live view mode, a continuous shooting rate of up to 8
fps is also possible.
Fast Hybrid AF System
An evolved 4D FOCUS system now employs a
combination of 693 phase-detection points, which cover approximately 93% 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 a7 models,
as well as improved low-light focusing. 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.
The apt focus system also lends itself to a variety of focusing functions for
refined accuracy, including Lock-on AF, which maintains focus on moving
subjects throughout the use of a configurable frame that is set over the
desired moving subject, and Expand Flexible Spot, which employs neighboring
focus points to retain focus on moving subjects even if the originally selected
point loses focus. Additionally, Eye AF can be used to base focus on recognized
subjects' eyes for portraits and is available in both AF-S and AF-C modes.
Autofocus can also be used in conjunction with the Focus Magnifier function for
critical focus when homing in on minute subject details. The rear touchscreen
can also be used for Touch Focus control, and a Touchpad Focus Control mode
lets you use the rear screen intuitively while keeping your eye to the
viewfinder.
5-Axis SteadyShot INSIDE Image Stabilization
Packed into the robust a7 III is a 5-stop
effective 5-axis SteadyShot INSIDE image stabilization system that compensates
for five different types of camera shake encountered during handheld shooting
of stills and video. This allows users to confidently use any lens, even
adapted lenses, for critical imaging without encountering blur from camera
shake.
For long focal lengths, the system will correct for pitch and yaw adjustments.
Macro and high-magnification imagery, on the other hand, will benefit from the
inclusion of horizontal and vertical shift compensation. All shooting styles
will get usage out of the roll compensation. All 5 axes of stabilization will
function at all times, even when used with third-party lenses and adapters or
lenses with built-in optical stabilization.
UHD 4K Video Recording in XAVC S Format
Internal recording of UHD 4K movies is
possible in multiple frame rates up to 30 fps and using 2.4x 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 Mb/s 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.
Affording extensive customizable color and gamma controls, the a7 III allows
users to adjust the gamma, black level, knee, color level, and more. Also,
users can use the same S-Log2 Gamma Curve that is found on high end Sony Cinema
cameras that squeezes up to 1300% more dynamic range into the video signal then
traditional REC709, for increased post-production flexibility. HLG (Hybrid
Log-Gamma) support is also available, along with the BT.2020 color space, for
recording within a wide color gamut and, in addition to S-Log2, S-Log3 is also
available for producing an effective 14-stop dynamic range with increased
grading control in the shadow to mid-tone regions of the image.
