Sony is on a full frame mirrorless camera roll that cannot be matched. They keep pushing the boundaries of technology and making products that are the envy of the industry. And now they're at it again the new A7 III (model ILCE-7M3).

A73_front_US.jpgThe A7 II  was a mirrorless marvel that kind of helped pave the way for all of Sony's success when it was released a little over three years ago. It was the world's first full-frame camera to have 5-axis image stabilization and at $1700 bucks was a bargain. So how does Sony top that? They not only improve the camera by leaps and bounds... they created a camera that fits nicely in between the A7R III and the A7S II. 

A73_rear_US.jpgSony is calling the new full-frame A7 III their new basic model, but it's anything but. Who else is making a camera that can shoot 4K HDR video with 5-axis IBIS, 120fps HD, and 15 stops of dynamic range... for under $2,000. 

Here are the top five A7 III improvements you'll see over the A7 II:


Sony developed a brand new sensor just for this camera. A full-frame 24.2MP Back-Illuminated Exmor R CMOS Image Sensor that has Evolved Image Processing. The old sensor on the A7 II was also 24.2MP but couldn't shoot 4K. Sony has learned a lot from their A7S II and A7R III as this beast of a camera can record 4K HDR video oversampled from 6K full pixel readout at up to 30 fps in S-Log2 and S-Log3. The new image processor also gives the camera a 1.5 stop improvement. 


The previous generation had 117-point focal plane phase detection AF sensor with 25 contrast detection AF points. The A7 III has a crazy 693 phase-detection AF points that cover 93% of the image area. It also has 425 contrast AF points and a new fast and reliable Eye AF that will keep subjects eyes and face in focus even when they're on the move. In real-world terms, the new system is twice as fast as the old system! 


The original A7 II had an ISO range of 100-25600 (expandable to ISO 50-51200 with multi-shot NR). The new A7 III is expandable up to 204,800. Four times the ISO range! Again it's good to have parents like the A7S II and the A7R III to borrow traits from. This could make the A7 II a low light monster. 


The A7 III has dual UHS-II SD card slots, so, you no longer do you have to fear or be afraid corrupt data. It was a feature that was a welcome addition to the A7R III as well. It also has a USB-C now for faster downloads. 


This is a big one. The A7 II was plagued with low battery life, but Sony has built the A7 III around the new Z Battery from the A9 and A7R III which, on this camera, is capable of up to 710 images on a single battery charge. That's a lot of pictures, and with its fancy new sensor will probably be a lot longer video shooting time for many people. 

This is a "basic" model that could outperform some manufacturers top of the line cameras. It's refreshing to see a company not hamstring a lower priced model and give it many of the features it's bigger siblings have. 

The A7 III goes on sale on April 10, 2018 for $1,999.99 US for the body only and $2200 in a kit with the FE 2870 mm F3.55.6 lens. Pre-order your Sony A7 III via here:

LAS VEGAS, Feb. 26, 2018 - Sony Electronics, a worldwide leader in digital imaging and the world's largest image sensor manufacturer, has today introduced yet another impressive addition to their full-frame mirrorless camera lineup, the α7 III (model ILCE-7M3).    

Sony's unmatched innovation within the image sensor space is at the forefront of the new α7 III, as it features a brand new 24.2MPi back-illuminated Exmor R CMOS image sensor with increased sensitivity, outstanding resolution and an impressive 15 stopsii of dynamic range at low sensitivities.   By combining this sensor with a variety of impressive features including extreme AF coverage of 93%, fast shooting at up to 10 fpsiii with either mechanical shutter or silent shootingiv, diverse 4Kvi video capabilities and more, Sony has created a new tool that gives all types of creators - from enthusiast to professional - the ability to capture content in new and different ways than they ever have before.

 "We are continually pushing to deliver more for our customers - more versatility, more functionality and most importantly, more innovation," said Neal Manowitz, Vice President of Digital Imaging for Sony Electronics.  "With the new α7 III, we've taken many of our newest and most advanced imaging technologies from the acclaimed α9 and α7R III models and paired them with an all-new 24.2 MP back-illuminated sensor to deliver the ultimate full-frame camera for enthusiasts, hobbyists and professionals alike.  It's a camera that punches far above its weight class in every capacity.  Combined with our impressive selection of 26 native full-frame E-mount lenses, it provides a level of performance that is simply unmatched in the industry." 



Spectacular Full-frame Image 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 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.  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 an overall 1.5 stopix improvement in image quality.  The camera also features a massive 15-stopii dynamic range at low sensitivity settings, ensuring outstanding overall performance at all settings and in all shooting conditions, with significant advancements in accurate color reproductions of skin tones and the vibrant colors of nature. 

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

Significant Advances in AF Speed and Performance

The innovative new α7 III full-frame mirrorless camera features a level of AF performance that has been largely improved over the α7 II, including 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 system inherited from the acclaimed α9 model.  This innovative AF system covers approximately 93% of the frame, ensuring reliable focusing and tracking for even the most difficult to capture subjects. 

AF response and tracking has also been greatly improved in the new camera, with almost 2xii 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 allows 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, even in AF-C mode, which is extremely useful for situations where the subject is turning around, looking down or otherwise obstructed.  It also works when the α7 III is being used with Sony's  A-mount lenses with an optional LA-EA3 adaptor[x].  Additional improvements in focusing flexibility include the addition of a multi-selector or 'joystick' for moving focusing points quickly, the addition of touch focusing capability, AF availability in Focus Magnifier mode, an 'AF On' button and much more. 

Speed to Capture Every Decisive Moment

The new α7 III is equipped with an updated image 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 Standard JPEG images, 89 compressed RAW images or 40 uncompressed RAW images[xi].  This high speed mode is available with either a mechanical 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 mode with minimal lag in the viewfinder or LCD screen. 

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

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

High Quality 4K Video

The new α7 III is an outstanding video camera as well, offering 4Kvi (3840x2160 pixels) video recording across the full width of the full-frame image sensor.  In video mode, the camera uses full pixel readout without pixel binning to collect about 2.4x[xiii] 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 (Hybrid Log-Gamma)[xiv]  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 imagery.  Further, both S-Log2 and S-Log3 are available for increased color grading flexibility, as well as Zebra functionality, Gamma Display assist 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 into4x or 5x slow motion video files in Full HD resolution with AF tracking.

Upgraded Build, Design and Customization

Sony's newest full-frame camera is equipped with a variety of enhanced capabilities that were first implemented in the α9 and then again in the α7R III.  These include dual media 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 cards, including separate JPEG / RAW recording, separate still image / movie recording, relay recording and more.  Battery life has been greatly extended 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 utilizes Sony's Z series battery NP-FZ100 that have approximately 2.2 times the capacity of the W series battery NP-FW50 utilized in the α7 II.

The new camera features "My Menu" functionality which allows up to 30 menu items to be registered for instant recall when needed. Users can also apply star ratings to their still images 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 total of 81 functions that are assignable to 11 custom buttons, and the camera is both dust and moisture resistant.[xv]

The α7 III features high-resolution, high-contrast, fast-start XGA OLED Tru-Finder™ with approximately 2.3 million dots for extremely accurate, true-to-life detail reproduction.  "Standard" or "High" 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, tablet, 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 supply and faster image transfer speed during tethered shooting.

The α7 III model also comes with Sony's new software suite "Imaging Edge", which extends the creative capabilities of the entire shooting process - from pre-processing to post-processing.   "Imaging Edge" provides three PC applications called 'Remote', 'Viewer' and 'Edit', available for free download, which support live-view PC remote shooting and RAW development.    In the latest Version 1.1, several improvements have been implemented including about 10%[xvi] faster data transfer speed for remote shooting from PC (PC tether shooting) and about 65%[xvii] improvement in the response speed for RAW image editing.  For more information, please visit Imaging Edge support page.
