Sony A7 III Overview

By B&H Photo's
Sony a7 III Mirrorless Camera
Well-Rounded Perfection
Distinguished by its updated sensor design, the Sony 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 low-light performance, a new 24.2MP Exmor R BSI CMOS sensor and BIONZ X processor benefit image quality, video capabilities, and AF performance. The a7 III also sports a revised body design, with a new touchscreen LCD, improved EVF, larger battery, and dual memory card slots.
Full-Frame BSI Sensor and BIONZ X 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. The BSI design also 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.
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 2.4x oversampling, which renders greater detail, and full pixel readout is possible, too, for higher quality imagery with reduced moiré and aliasing. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both 4K and FHD 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.
S-Log3, HLG, and Other Color and Gamma Controls
Affording extensive customizable color and gamma controls, the a7 III allows users to adjust the gamma, black level, knee, color level, and more. Shooters 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 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.
Autofocus and Image Stabilization
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.
  • Lock-on AF maintains focus on moving subjects through the use 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-S and AF-C modes
  • Focus Magnifier function can be used for critical focus when homing in on minute subject details
  • 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.
Body Design and Connectivity
  • The XGA OLED Tru-Finder EVF features a 2.36m-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 design for intuitive operation and focusing control. The screen also tilts upward 107° and downward 41° to benefit working from high and low angles.
  • Magnesium-alloy chassis assures rigidity, durability, and stability while remaining lightweight. The lens mount has also been improved to better support heavy lenses and the grip rigidity has been improved for more comfortable 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 III has improved battery life and is now rated for approximately 710 shots per charge.
  • Dual SD memory card slots allow for flexible file saving and handling, and can be configured to partition raw and JPEG files or can be used for overflow recording. One of the card slots is rated to support UHS-II memory cards.
  • A USB 3.0 Type-C port has been added, in addition to a micro-USB port, for faster, more reliable tethering support. The USB Type-C connection allows the 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 direct sharing online to social networking, via email, and to cloud storage sites.
  • NFC (Near Field Communication) is also supported, which allows for one-touch connection between the camera and compatible mobile devices; no complex set-up is required. Once connected, the linked mobile device can also display a live view image on its screen and remotely control the camera's shutter.
  • Bluetooth connectivity allows for location data acquisition.
Sony FE 28-70mm f/3.5-5.6 OSS Lens
A Versatile Standard
A top pick for users looking for a lightweight all-around zoom, the FE 28-70mm f/3.5-5.6 OSS Lens from Sony is a great go-to for full-frame E-mount shooters. The lens has a compact, portable design that is ideal for everyday, walkaround use and its versatile wide-angle to portrait-length range suits working with a variety of subject types.
Optical Design
  • One extra-low dispersion glass element is featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality.
  • Three aspherical elements are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
  • Rounded seven-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
Autofocus, Image Stabilization, and Design
  • An internal focus mechanism and linear motor contribute to faster, more responsive system and easier handling.
  • Optical SteadyShot image stabilization helps to minimize the appearance of camera shake for sharper imagery when shooting handheld with slower shutter speeds. This stabilization system can be combined with select camera's sensor-shift type image stabilization for more effective control of camera blur.
  • Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.

question

I live in a caribbean coastal city (Barranquilla) with humidity and apron 30-35C all year. For video, I need to do interviews on the outside in the sun, maybe shade, still very hot. Ive read a lot that Sony's Alpha 7 line are poorly weather sealed and water and corrosion is usual. My Canon 7D take time to overheats but still happened, but buying a new camera is to overcome this. I wanted to upgrade to the A7III, but there are mixed reviews, some saying it won't stand more than 8 mins 4k video in sun 32 aprox and that corrosion is very common. Is this camera good for outside video with tough conditions?
Asked by: Danilo S.
I would say that from what I am seeing and hearing, the Sony a7 III is the most heat and weather resistant of all the a7 cameras Sony has ever made. Therefore if you have this camera, when you are shooting in extreme conditions you have to consider best practices. You can't expect the camera to work flawlessly all by itself without protection. This has been true ever since the first camera took a picture. Keep the camera cool in the car, keep a white towel over it, use an umbrella, use an external recorder/monitor, use an external power supply, keep the battery door open while shooting interiors, and keep the rear screen away from the body. If that is not enough, you might consider a camera with a smaller sensor like the Panasonice GH5s.

question

Tracking Birds in flight how does it do compared with a Nikon D500?
Asked by: Tim
With a Sony G lens, the a7 III will be as good if not better than the Nikon D500. If you put a third party lens on, the performance will lag in comparison. It will be good, just not sterling.

The only difference of buying the new equipment ...

The only difference of buying the new equipment that is included with the accessory kit with the used equipment is that the used equipment does not include the accessory kit, is this correct?
Asked by: Emilio
It is always best to call the location that has the used gear to verify what’s is included and the condition of the item. As far as the accessory kit is concerned, it comes with a memory card and a spare battery. The memory appears to be the kind which will only work in memory slot 2, not the primary slot. The spare battery is a third party brand which will likely not last as long as the Sony brand, and is more likely to fail. I recommend buying the camera separate and choosing a better battery and memory card.
