Sony α7 III Full-frame Mirrorless Interchangeable-Lens Camera
The a7 III has been refined for extraordinary image capture control and quality from the next generation 24.2MP full-frame BSI image sensor and latest BIONZ X image processor, down to the smallest operational detail. Featuring 693 phase AF points with up to 10fps1 continuous shooting 4K2 HDR3 video and the longest7 battery life of any mirrorless camera to date – the a7 III has everything you need (shown here with the Sony SEL2870 lens).
Newly developed 24.2MP BSI Full-frame Image Sensor
The newly developed 24.2MP back-illuminated Exmor R CMOS image sensor is paired with a front-end LSI that effectively doubles the readout speed of the image sensor, as well as an updated BIONZ X processing-engine that boosts processing speed by approximately 1.8 times compared to the α7 II. This results in high sensitivity with low-noise performance and wide 15-stop4 dynamic range. It also has the ability to output 14 bit RAW4 format even when shooting in silent5 or continuous mode. Nothing less than spectacular images.
Evolutionary leap in image processing power
The a7 III features a new front-end LSI that effectively doubles the readout speed of the image sensor, as well as an updated BIONZ X processing-engine that boosts processing speed by approximately 1.8 times compared to the a7 II. These powerful components work together to allow the camera to shoot at faster speeds while also enabling its impressive ISO range of 100 – 51200 (expandable to ISO 50 – 204800 for still images and massive 15-stop4 dynamic range at low sensitivity settings. This ensures outstanding overall performance at all settings and in all shooting conditions.
Up to 10fps1 with Silent5 or Mechanical Shutter
The a7 III is equipped with a refined image processing system that allows it to capture full 24.2MP images at up to 10 fps1 with continuous and accurate AF/AE (autofocus and auto exposure) tracking for up to 177 Standard JPEG images, 89 compressed RAW images or 40 uncompressed RAW images. This high speed 10 fps mode is available with either a mechanical shutter or an electronic shutter for completely silent5 shooting. The a7 III can also shoot continuously at up to 8 fps1 in live view mode with minimal lag in the viewfinder or LCD screen. These high speed options ensure that fast moving subjects can be captured with extreme accuracy and incredible image detail.
5-step6, 5-axis in-body image stabilization
The 5-axis in-body SteadyShot image stabilization system has been fine-tuned to support high-resolution shooting capacity, resulting in an image stabilization system at 5-step6 shutter speed advantage. Camera shake is effectively compensated on 5 axes: pitch and yaw that have the largest overall impact on image quality; X and Y shift that is most apparent at high magnification, and roll that can ruin night shots and movies. Stabilization is applied to the live-view image, making it easier to frame fast-moving subjects. Effective stabilization is provided for movies as well as stills, and for A-mount lenses9 attached via a mount adapter.
Secure and versatile dual SD media slots
Two SD media card slots are provided for still and movie storage (one slot for SD cards or Memory Stick) with the lower card slot being UHS-II compatible for fast write speed. Still or movie data can be simultaneously recorded to both cards for backup, or RAW4 images can be recorded to one card while JPEG images are recorded to the other. It is also possible to record stills and movies to different cards. Relay recording automatically switches to the second card when the first card is full. Data can be copied between cards while in the camera, for convenient back-up. Sony SF-G series UHS-II SD cards are ideal for situations where maximum transfer speed is required.
16-bit processing and 14-bit RAW4 output for natural gradations
Both compressed and uncompressed 14-bit RAW4 format are supported. The 14-bit digital signal from the image sensor’s analog to digital (AD) converter is processed in 16-bit form by the front-end LSI and BIONZ X image processor before being output as 14-bit RAW4 data. The result is smoother, more natural gradations that contribute to higher overall image quality. The enhanced BIONZ X image processing LSI makes 14-bit RAW4 output available even when shooting in silent5 or continuous mode.
Footnotes:
1 In continuous ‘Hi+’ mode. Max. fps depends on camera settings. UHS-II compatible SDXC memory card required.
2 Class 10 or higher SDHC/SDXC card required for XAVC S movie recording, UHS speed class 3 or higher for 100 Mbps recording.
3 Connect to an HDR (HLG) compatible Sony TV via a USB cable to view HDR (HLG) movies.
4 Sony test conditions
5 Some distortion may occur with fast-moving subjects.
6 CIPA standards. Pitch/yaw shake only. Planar T* FE 50mm F1.4 ZA lens. Long exposure NR off.
922K-dot (approx.) 3” (3.0 type) tilting LCD monitor
This large tiltable 3” (3.0 type) LCD monitor features approximately 922K dots for high resolution and detailed viewing. The monitor not only supports touch operation, but tilts upwards by a maximum of 107 degrees and downwards by a maximum of 41degrees for flexible hold and framing.
Footnotes:
10 Only 100 Hz and 120 Hz flicker is detected. Continuous shooting speed may decrease. Flicker-free shooting is not available during silent5 shooting, BULB exposure, or movie recording.
11 5x at 24p recording and 4x at 30p.
12 Not guaranteed to be 100% dust and moisture proof.
13 Measured with: CPU Intel Core i7-6700 Processor 3.40GHz, Memory 8GB, OS Windows 7 Professional, and Uncompressed RAW (α7R III L: 7952 x 5304)
Touch AF function
Focusing doesn’t get any more intuitive than this. With Touch Focus you can simply touch the LCD screen to specify the desired focus point. Even subjects near the edges of the frame can be instantly selected without having to reframe or manually shift the focus point. Double-tap any point on the monitor for a magnified view of that area when focusing manually. Touch AF allows smooth focus point changes when shooting movies too.
