    Well-Rounded Perfection

    Distinguished by its updated sensor design, theSony a7 Iii is a well-rounded camera suitable for both photo and video applications in a variety of working situations. Refined for improved speed and depression-light performance, a new 24.2MP Exmor R BSI CMOS sensor and BIONZ Ten processor do good image quality, video capabilities, and AF functioning. The a7 III too sports a revised body design, with a new touchscreen LCD, improved EVF, larger battery, and dual memory bill of fare slots.

    Full-Frame BSI Sensor and BIONZ X Processor

    Featuring a back-illuminated design, the total-frame 24.two-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. The BSI pattern also dramatically improves data transmission speed for creating 14-chip, loftier-resolution stills with a native sensitivity range from ISO 100-51200, which tin be further expanded to ISO 50-204800. Also, it enables internal UHD 4K video recording with a wide dynamic range using the total width of the full-frame sensor. The BIONZ Ten processor also works in conjunction with a high-speed front end-end LSI to realize faster processing times along with the ability to capture an impressive xv-finish dynamic range at low sensitivity values.

    The sensor and processor combination also avails fast continuous shooting at upward to x 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 way, a continuous shooting rate of up to 8 fps is also possible.

    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 uses ii.4x oversampling, which renders greater particular, and full pixel readout is possible, as well, for higher quality imagery with reduced moiré and aliasing. Total Hd 1080p recording is besides supported in frame rates up to 120 fps, and both 4K and FHD resolutions utilize the 100 Mb/due south XAVC S format contained inside an MP4 wrapper with 4:two:0 sampling.

    The high-speed, 120 fps recording likewise enables 4x and 5x slow-movement picture show recording with the frame rate set to either 30p or 24p. In addition to high-resolution internal recording, uncompressed HDMI output likewise enables the use of an optional external recorder for make clean 4K recording with 4:2:two sampling.

    Southward-Log3, HLG, and Other Color and Gamma Controls

    Affording extensive customizable color and gamma controls, the a7 III allows users to adjust the gamma, blackness level, knee, color level, and more. Shooters can use the same S-Log2 Gamma Curve that is plant on high stop Sony Picture palace cameras that squeezes up to 1300% more dynamic range into the video signal then traditional REC709, for increased mail-product flexibility.

    HLG (Hybrid Log-Gamma) support is available, along with the BT.2020 colour space, for recording inside a wide color gamut and, in addition to S-Log2, S-Log3 is also bachelor for producing an constructive xiv-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.

    Autofocus and Image Stabilization

    Fast Hybrid AF System

    An evolved 4D FOCUS organisation now employs a combination of 693 stage-detection points, which cover approximately 93% of the frame, along with 425 contrast-detection areas for reliable and quick autofocus and bailiwick tracking functioning. This Fast Hybrid AF Organization now achieves twice the focusing speed and more than reliable tracking compared to previous a7 models, as well as improved low-lite focusing.

    • Lock-on AF maintains focus on moving subjects through the utilize of a configurable frame that is set over the desired moving subject
    • Expand Flexible Spot employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus
    • Eye AF can be used to base focus on recognized subjects’ eyes for portraits and is available in both AF-Due south and AF-C modes
    • Focus Magnifier function tin be used for disquisitional focus when homing in on infinitesimal bailiwick details
    • Rear touchscreen can too be used for Touch on Focus control and a Touchpad Focus Control way lets y’all use the rear screen intuitively while keeping your eye to the viewfinder

    v-Axis SteadyShot Inside Epitome Stabilization

    Packed into the robust a7 III is a 5-terminate constructive 5-axis SteadyShot Within image stabilization organisation that compensates for five different types of camera milk 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 milkshake.

    For long focal lengths, the arrangement volition 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 whorl bounty. All 5 axes of stabilization volition function at all times, even when used with tertiary-party lenses and adapters or lenses with congenital-in optical stabilization.

    Body Blueprint and Connectivity

    • The XGA OLED Tru-Finder EVF features a ii.36m-dot resolution and 0.78x magnification for bright, clear viewing in high detail.
    • In addition to the EVF, a 3.0″ 922k-dot rear LCD is also available, which has a touch panel blueprint for intuitive operation and focusing command. The screen also tilts upward 107° and downward 41° to benefit working from high and low angles.

    • Magnesium-alloy chassis assures rigidity, immovability, and stability while remaining lightweight. The lens mount has also been improved to better back up heavy lenses and the grip rigidity has been improved for more comfy hand-holding.
    • Weather-sealing has been employed to resist dust and moisture for reliable operation in harsh weather conditions.
    • Using the NP-FZ100 battery, the a7 Three has improved battery life and is now rated for approximately 710 shots per accuse.
    • Dual SD retention menu slots let for flexible file saving and treatment, and tin can be configured to sectionalisation raw and JPEG files or tin be used for overflow recording. One of the carte slots is rated to support UHS-II retentiveness cards.
    • A USB three.0 Blazon-C port has been added, in addition to a micro-USB port, for faster, more reliable tethering support. The USB Blazon-C connection allows the photographic camera to be charged from the host power source while connected.
    • Built-in Wi-Fi enables the a7 Iii to instantly share imagery to mobile devices for straight sharing online to social networking, via email, and to cloud storage sites.
    • NFC (Near Field Communication) is also supported, which allows for ane-touch connectedness betwixt the camera and compatible mobile devices; no complex set-up is required. Once continued, the linked mobile device can also brandish a alive view prototype on its screen and remotely control the photographic camera’s shutter.
    • Bluetooth connectivity allows for location data acquisition.
