Sony Announces the Much Anticipated Sony A7rIII!

When Sony released the Sony a7RII over two years ago, they had promptly rewrote the rulebook on what could be expected from a mirrorless camera, and cameras in general. With more megapixels, more stabilizing power, and more tech than we’d previously seen in a tangible ILC, it was beyond what anyone had expected in the day. And now it’s been superseded by the A7rIII.

Key Stats:

  • 35mm Full-Frame 42.4 MP Back-Illuminated Exmor R™ CMOS Image Sensor with Evolved Image Processing
  • Continuous Shooting at up to 10 fps with either Silent Shooting or Mechanical Shutter and full Auto Focus/Auto Exposure tracking
  • 399 phase-detection AF points covering 68% of image area, 425 contrast AF points and approximately 2 times more effective Eye AF
  • 5-axis optical in-body image stabilization with a 5.5 step shutter speed advantage
  • High Resolution 4K Movie Shooting with full pixel readout and no pixel binning
  • Completely redesigned for professionals, including upgraded Auto Focus, Dual SD Card Slots, Extended Battery Life, SuperSpeed USB (USB 3.1 Gen 1) USB Type-C™ Terminal and more Compact, Lightweight body at only 23 oz8

The A7rIII is a new mirrorless camera that builds on where the a7RII left off, and does so largely by borrowing some of the tech of the A9. The result is a camera that looks almost identical to the a7RII, but with totally revamped innards, and a few much welcomed additions, like dual SD card slots (UHS-II, UHS-1), a focus-point multi-selector (joystick), and though they initially said it couldn’t be done, Sony has enabled the A7rIII to now use the same high-capacity battery found in the A9.

The A7rIII can also take the same battery grip as the A9, and the same 3.7 million dot OLED electronic viewfinder of the A9, and a rear LCD which can be used for focus as an AF touchpad.

While the sensor remains the same, Sony now offers the more powerful Bion Z X processor paired with the frone-end LSI allows for much quicker data processing and transfer.

Paired with the newly designed shutter mechanism, the A7rIII is capable of 10FPS across the range, and what that means is you can shoot 10FPS on essentially every setting and get the most out of it. That means you can shoot the highest fps with every AF setting in either mechanical or electronic / silent shutter mode. And you can do that for 87 compressed raw or 28 uncompressed images. Singular uncompressed files are 14 bit with a whopping 15 stops dynamic range, and drop to 12 bit when shooting at the highest fps.

Beyond that there is the IBIS system of image stabilization which remains the same 5 axis but performs to a higher standard giving an extra stop of relief. This, combined with the new shutter mechanism helps the A7rIII by reducing shutter shock – a major problem in high resolution cameras.

In the quest for better resolution the A7rIII has a new Multi-shot pixel-shift resolution mode, which shoots a full four images and will move the sensor at the micron level to ensure each pixel position gets the full red, blue, and green pixels. This eliminates         de-moisaicing and realizes 170 million pixels of data to make a single 42 MP file. The benefits of this are much truer color, and overall a more ‘true’ resolution (keep in mind that the resolution your camera puts out isn’t generally more than 1/4 of what’s stated and the rest is interpolating etc.).

Then of course the video capabilities which will do full sensor 4K and ‘5k’ in Super35 mode. Video also gets all the benefits of the updated AF system and the stabilizing system, and the A7rIII gets a Hybrid Log Gamma feature and SLog-3.

Then of course there’s the multi-USB ports, including a micro-USB and for the first time a USB 3.1 type-C port, both of which can be used simultaneously for different functions – such as tethering and powering at once.

Pricing on the camera is believed to be below Nikon’s D850, starting around $3,199 and will be available at the end of November, just in time for the holidays.
