( Outdoor Raw Pics ) Sony a7iii Image Quality Test in Wedding Photography, Pre-Wedding Shoot, Candid Photography & Studio

 Featuring an improved sensor design, the Sony Alpha a7 III Mirrorless Digital Camera is a well-rounded camera suitable for both photo and video applications in a variety of work situations. Enhanced for higher speed and low-light performance, the full-frame 24.2MP Exmor R BSI CMOS sensor and BIONZ X image processor deliver an impressive 10fps continuous shooting speed and improved autofocus performance for faster and more reliable subject tracking along with wide-angle shooting. frame coverage. This updated Fast Hybrid AF system uses a combination of 693 phase-detection points and 425 contrast-detection areas to focus faster in various lighting conditions, as well as focus on subjects more efficiently. In addition to speed and AF, the processing improvements also help achieve greater image clarity and noise reduction throughout the sensitivity range from ISO 100-51200, which can be further extended to ISO 50-204800. Video recording capabilities have also been improved for better quality when recording UHD 4K video with a full-frame sensor to minimize moirĂ© and aliasing. In addition, the A7 III uses 5-axis SteadyShot INSIDE image stabilization, which now effectively minimizes camera shake by up to 5 EVs, making the most of both stills and video.



Aside from just updates to the display system, the a7 III's body design has also been revised to include a rear 3.0″ 922k dot touchscreen LCD that has a tilting design to better support working from both high and low angles. The 2.36m-dot Tru-Finder OLED EVF is also equipped for clear, eye-level viewing. There are now two SD memory card slots for more shooting flexibility, and the NP-FZ100's larger battery is also used to achieve around 710 shots per charge. With a magnesium alloy chassis and weather sealing, the a7 III is dust and moisture-resistant, suitable for use in harsh environments.

A full-frame 24.2-megapixel Exmor R CMOS sensor with a back-illuminated design works with the BIONZ X image processor to deliver high-resolution photos and video while minimizing noise and increasing speed. This sensor structure works with a gap-free on-chip lens design and an anti-reflective coating to improve light collection and enhance detail. The copper cable layer also dramatically improves data transfer rates for producing high-resolution 14-bit still images with a native sensitivity range of ISO 100-51200, further expandable to ISO 50-204800. It also enables internal recording of UHD 4K video 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 achieve faster processing times, along with the ability to capture an impressive 15 feet of dynamic range at low sensitivity values.

Key features of Sony a7iii

  • 24MP Full-Frame Exmor R BSI CMOS sensor
  • BIONZ X image processor and front-end LSI
  • The 693-point hybrid AF system
  • UHD 4K30p video with HLG and S-Log3 Gammas
  • 2.36m-Dot Tru-Finder OLED EVF
  • 3.0" tiltable touch LCD display with a resolution of 922,000 dots
  • 5-axis SteadyShot stabilization INSIDE
  • ISO 204800 and 10 fps shooting
  • Built-in Wi-Fi and NFC, two SD slots
  • USB Type-C port, weatherproof design


The sensor and processor combination also uses fast continuous shooting at up to 10 frames per second in full resolution, up to 177 consecutive shots, and with continuous AF/AE when working with a mechanical or electronic shutter. Continuous shooting at up to 8 frames per second is also possible when shooting in Live View mode.


The evolved 4D FOCUS system now uses a combination of 693 phase-detection points that cover approximately 93% of the frame, along with 425 contrast-detection areas for reliable and fast autofocus and subject tracking. 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 allows the use of A-mount lenses via the optional LA-EA3 or LA-EA1 lens mount adapter with full AF/AE continuous tracking compatibility.

The apt focus system also lends itself to a variety of focus functions for improved accuracy, including Lock-on AF, which maintains focus on moving subjects throughout the use of a configurable frame that is set to the desired moving subject and Expand Flexible Spot, which utilizes adjacent focus points to maintain focus on moving objects even if the originally selected point loses focus. Additionally, Eye AF can be used to focus on eye-detected subjects in 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 the touchpad focus control mode allows you to use the rear screen intuitively while keeping your eyes on the viewfinder.

Built into the robust a7 III is the 5-step effective 5-axis SteadyShot INSIDE stabilization system, which compensates for five different types of camera shake that occur when shooting handheld photos and videos. This allows users to confidently use any lens, even custom lenses, for critical shots without experiencing blur due to camera shake.


At long focal lengths, the system corrects tilt and yaw settings. Macro shots and high magnification shots, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will benefit from tilt compensation. All 5-axis stabilization will work in all circumstances, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.

Internal UHD 4K movie recording is possible at multiple frame rates up to 30 frames per second and the use of 2.4x oversampling provides greater detail and full pixel readout is possible that is free of pixel binning for higher image quality with reduced moiré and aliasing. Full-frame 4K recording has also been significantly improved for better quality when working at medium to high sensitivities to make full use of the sensor's full width. Full HD 1080p recording is also supported at up to 120 frames per second, and both resolutions use the 100Mbps XAVC S format contained in the MP4 wrapper with 4:2:0 sampling. 120 fps high-speed recording also allows for 4x and 5x slow-motion video recording with the frame rate set to 30p or 24p. In addition to internal high-definition recording, the uncompressed HDMI output also allows the use of an optional external recorder for clean 4K recording with 4:2:2 sampling.

The A7 III offers extensive customizable color and gamma controls, allowing users to adjust gamma, black level, knee, color level and more. Users can also use the same S-Log2 Gamma Curve found on high-end Sony Cinema cameras, which squeezes up to 1300% more dynamic range into the video signal than the traditional REC709, increasing post-production flexibility. HLG (Hybrid Log-Gamma) support is also available, along with the BT.2020 color space for wide color gamut recording, and in addition to S-Log2, S-Log3 is also available to produce an effective 14-foot dynamic range with increased gradation control in shadows up to midtones of the image.
