As expected, Sony has announced its latest high-resolution full-frame mirror-less digital camera named Sony Alpha A7R III Digital Camera in Australia which sounds similar to Nikon’s recent D850. The Alpha A7R is a mixer of high speed and fast autofocus capabilities to a degree which we have, so far, not seen. A predecessor of A7R is built around a 42MP BSI CMOS sensor, but Alpha A7R III capture images at 10fps. The highlights of Alpha A7R III are related to fastest processor, improved autofocus, ergonomics, and improved managing as well as an adoption of a whopping battery.

Key Features

  • Twin SD card slots (one UHS-I and one UHS-II compatible)
  • Availability of PDAF (Phase Detection Autofocus) at 3fps with adapted lenses
  • 42MP BSI CMOS sensor
  • Quick, shake-free, and lower-noise image processing
  • Improved autofocus including more tenacious Eye AF Mode
  • 10fps shooting with full AF, 8fps with Live updates between shots
  • 4K footage from “Super 35” crop region oversampled from 5K capture
  • 5-Axis Image Stabilization, rated at 5.5 stops (CIPA) with 50mm lens
  • Video AF less inclined to refocus to background
  • 3.69M dot (1280 x 960 Pixels) OLED viewfinder
  • Picture profile video gamma/gamut modes including S-Log2 and 3
  • Bayer-cancelling multi-shot mode for improved resolution
  • True 14 bit uncompressed Raw, even in continuous drive mode
  • Sony Alpha A7R III Digital Camera Price in Australia is in-between the range of AU$4699-4899

It has been said that Sony Alpha A7R III is based around the same 42MP backside illuminated CMOS sensor which sounds similar to its predecessor. Though it doesn’t gain the full speed advantage of A9’s Stacked CMOS but an adoption of algorithms, refinements introduced and processing system on A9 all have such benefits. So, A7R with a dedicated joystick for AF point positioning and a touchscreen, a camera with improved customization and deeper grip – with long-lasting battery life and perfect laid-out menus.

Video Capabilities

Sony has also claimed that Alpha A7R III is capable enough to record full HD videos. To get an advantage of the camera’s dynamic range, Picture profile system of colour and tonal response borrowed from Sony’s professional video line now includes even flatter S-Log3 gamma curve. Well, users won’t be able to capture 10-bit images as camera still captures only 8-bit 4:2:0 footage internally which perhaps limit the usefulness of S-Log3 in case it makes posterization more likely when the footage is graded.

Users who are looking to use Sony Alpha A7R III’s dynamic range with a high dynamic range display without getting worried of colour grading, A7R III joins the Panasonic GHS in offering Hybrid Log Gamma recording – fundamentally Log capture with tags just to inform display how to correctly render it. 

Video Features

  • Enhanced Zebra Function

If you want to monitor exposure values in high-contrast screens, an enhanced Zebra function is ideally suited. Video signal level targets can easily be set from 0-109 as well as specific ranges can be set to make exposure level adjustments easier.

  • User Bit and Time Code Setting

A time code can be used in order to record hours, minutes, seconds and image data, whereas User Bit helps you record data, time and scene number to aid in editing together footage from several other cameras.

  • Proxy Recording

Here is where Sony Alpha A7R III really shines as proxy movies and UHD 4K movies can be recorded simultaneously. The smaller proxy files are ideal for quick previewing or pre-editing which can reduce the time required for final 4K editing.
