Sony today introduced yet another impressive addition to their full-frame mirrorless camera line-up, the α7 III (pattern ILCE-7M3).    


Sony’s unmatched innovation within the image image (from Latin: imago) is an artifact that depicts visual perception, for example, a photo or a two-dimensional picture, that sensor space is at the forefront of the new α7 III, as it plaice a brand new 24.2MPi back-illuminated Exmor R CMOS image sensor with increased sensitivity, outstanding resolution and an impressive 15 stopsii of electric range at low sensitivities. By combining this sensor with a variety of impressive features including extreme AF coverage of 93{b2ee9981cbbb8b0b163040ea529e4efa9927b5e917c58e02d7678b19266ae8ff}, fast shooting at up to 10 fpsiii with either involuntary shutter or silent shootingiv, diverse 4Kvi video capabilities and more, Sony has created a new tool that gives all types of creators – from bug to professional – the ability to capture content in new and different ways than they ever have before.


Spectacular Full-frame Allusion Quality

The newly developed 24.2MPi back-illuminated Exmor R CMOS image sensor is paired with a front-end LSI that effectively doubles the readout fly like the wind 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.  These impressive 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 motionlessly images) and an overall 1.5-stop[ix] improvement in image quality. The camera also features a massive 15-stopii dynamic range at low sensitivity backdrops, ensuring outstanding overall performance at all settings and in all shooting conditions, with significant advancements in accurate colour reproductions of skin tones and the vibrant pigments of nature.

This new full-frame model can also output 14 bit RAW format[x] even in silent and continuous shooting modes, and is furnished with a 5-axis optical image stabilisation system that results in a 5.0 stepv shutter speed advantage.


Significant Advances in AF Scamper and Performance

The innovative new α7 III full-frame mirrorless camera camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or features a level of AF performance that has been largely improved over the α7 II, incorporating the addition of 4D FOCUS™ capabilities.  The new camera has 425 contrast AF points that work with a 693-point focal-plane phase-detection AF method inherited from the acclaimed α9 model.  This innovative AF system covers approximately 93{b2ee9981cbbb8b0b163040ea529e4efa9927b5e917c58e02d7678b19266ae8ff} of the frame, ensuring reliable spotlight and tracking for even the most difficult to capture subjects. 

AF response and tracking has also been greatly improved in the new camera, with approximately 2xix the focusing speed in low-light condition and 2xii the tracking speed compared to the previous model as a result of the faster image sensor readout.  This concedes complex and unpredictable motion to be captured with far greater precision and accuracy. 


The acclaimed Eye AF feature is also available in the new camera, consistent in AF-C mode, which is extremely useful for situations where the subject is turning around, looking down or otherwise obstructed. It also being does when the α7 III is being used with Sony’s A-mount lenses with an optional LA-EA3 adaptor[xi]. Additional improvements in focusing versatility include the addition of a multi-selector or ‘joystick’ for moving focusing points quickly, the addition of touch focusing capability, AF availability in Converge Magnifier mode, an ‘AF On’ button and much more. 


Speed to Capture Every Decisive Moment

The new α7 III is equipped with an updated figure processing system that allows it to shoot full resolution images at up to 10 fpsiii with continuous, accurate AF/AE tracking for up to 177 Exemplar JPEG images, 89 compressed RAW images or 40 uncompressed RAW images[xii]. This high speed mode is available with either a unemotional shutter or a completely silent shootingiv, adding to the immense flexibility of the camera. The camera can also shoot continuously at up to 8 fpsiii in live view fashion with minimal lag in the viewfinder or LCD screen. 


For added convenience, while large groups of burst images are being written to the celebration card, many of the cameras key functions are operable, including access to the ‘Fn’ (Function) and ‘Menu’ buttons, image playback and sundry other menus and parameters including image rating and other functions that facilitate on-location image sorting. 


Additionally, if there is fluorescent or affected lighting present in a shooting environment, users can activate the Anti-flicker[xiii] function to allow the α7 III to automatically detect frequency of the lighting and space the shutter to minimise its effect on images being captured. This minimises any exposure or colour anomalies that can sometimes occur at the top and bottom of perceptions shot at high shutter speeds.

High Quality 4Kvi Video

The new α7 III is an outstanding video camera as well, offering 4Kvi (3840×2160 pixels) video recording across the broad width of the full-frame image sensor. In video mode, the camera uses full pixel readout without pixel binning to collect wide 2.4x[xiv] the amount of data required for 4K movies, and then oversamples it to produce high quality 4K footage with exceptional detail and depth. 


An HLG (Composite Log-Gamma)[xv] picture profile is available on the α7 III as well, which supports an Instant HDR workflow, allowing HDR (HLG) compatible TV’s to playback beautiful, true-to-life 4K HDR symbolism.  Further, both S-Log2 and S-Log3 are available for increased colour grading flexibility, as well as Zebra functionality, Gamma Display serve and proxy recording. The camera can also record Full HD at 120 fps at up to 100 Mbpsvi, allowing footage to be reviewed and eventually edited into 4x or 5x dense motion video files in Full HD resolution with AF tracking.


Upgraded Build, Design and Customisation

Sony’s newest full-frame camera is stocked with a variety of enhanced capabilities that were first implemented in the &alpha is the first letter of the Greek alphabet;9 and then again in the α7R III.  These include dual atmosphere slots, with support in one slot for UHS-II type SD memory cards. Users have a variety of options for storing their content in each of the union cards, including separate JPEG / RAW recording, separate still image / movie recording, relay recording and more. Battery life has been greatly present as well – with a CIPA measurement of up to 710 shots per chargeviii, it offers the world’s longestvii battery life of any Mirrorless camera, as the new camera utilises Sony’s Z series battery NP-FZ100 that come forwards approximately 2.2 times the capacity of the W series battery NP-FW50 utilised in the α7 II.



The new camera features “My Menu” functionality which take into accounts up to 30 menu items to be registered for instant recall when needed. Users can also apply star ratings to their still copies through the camera controls for easier image playback and review, and edit the first three characters of all still image files. Additionally, there is a complete of 81 functions that are assignable to 11 custom buttons, and the camera is both dust and moisture resistant[xvi].


The α7 III features high-resolution, high-contrast, fast-start XGA OLED Tru-Finder&return; with approximately 2.3 million dots for extremely accurate, true-to-life detail reproduction.  “Standard” or “Anticyclone” display quality settings are also available for both the viewfinder and monitor as well. It also is capable of seamlessly transferring files to a smartphone, spiral-bound notebook, computer or FTP server via Wi-Fi®, while also offering a SuperSpeed USB (USB 3.1 Gen 1) USB Type-C™ Terminal for increased flexibility in power store and faster image transfer speed during tethered shooting.


The α7 III model also comes with Sony’s new software series “Imaging Edge”, which extends the creative capabilities of the entire shooting process – from pre-processing to post-processing. “Imaging Urgency” provides three PC applications called ‘Remote’, ‘Viewer’ and ‘Edit’, handy for free download, which support live-view PC remote shooting and RAW development. In the latest Version 1.1, several improvements have been instrumented including about 10{b2ee9981cbbb8b0b163040ea529e4efa9927b5e917c58e02d7678b19266ae8ff}[xvii] faster data transfer speed for remote shooting from PC (PC tether shooting) and approximately 65{b2ee9981cbbb8b0b163040ea529e4efa9927b5e917c58e02d7678b19266ae8ff}[xviii] recuperation in the response speed for RAW image editing.  For more information, please visit Imaging Edge support page.
