Global Announcement: Sony a7R IV — 61 Megapixel, Full-Frame Mirrorless Camera

July 17, 2019

A Revolutionary Development for Mirrorless Cameras

61.0 effective megapixels, true-to-life gradations, and blazing speed come together in a full-frame mirrorless camera body that is capable of capturing reality you can almost feel. Image quality and expression that were once only possible with medium-format cameras are now available in a compact, lightweight α series full-frame body with features, connectivity, and reliability designed to support professional workflows both in the studio and out on location. Stunning stills and movies with professional reliability and productivity.

Key Features:

  • World’s first 61 megapixel high resolution back-illuminated CMOS sensor 
  • 240 megapixel pixel shift multi shooting for medium format rivalling detail
  • 15-stop dynamic range, resulting in smooth natural gradations
  • ISO 100-32000 (expandable up to 102400) for optimum image quality in any light
  • AF/AE tracking for continuous shooting for up to 10 frames per second
  • 5.5-stop 5-axis in-body image stabilisation
  • 567 point focal plane phase-detection AF, covering approx. 74% of the image area
  • Improved object tracking & real-time Eye AF for humans and animals for stills
  • Real-time Eye AF for movies 
  • High-resolution 4K and professional movie features 
  • 5.76 million dot UXGA OLED viewfinder
  • Wireless PC Remote / 5 GHz Wi-Fi connection

The a7R IV features a newly developed 61 Megapixel back-illuminated image sensor, the first of its kind. This remarkable new sensor delivers 15 stops of dynamic range for extraordinarily detailed rendition of subtle details, while tweaked & refined algorithms ensure pleasing colours and skin tones.

Takes advantage of advanced in-body image stabilisation system control, capturing multiple pixel-shifted images that are later composited using a computer to achieve overwhelming resolution in a single image. 16-image composites with 240.8 million pixels deliver photographs with detail and presence that are simply stunning.

Combining 567 on-sensor phase detect autofocus points with refined tracking algorithms, the Alpha a7R IV boasts extraordinarily sophisticated autofocus abilities, with real-time tracking and eye autofocus enabled for both still and movie recording. All of this is available for full-speed 10 frames per second image capture with AF.



The body of the a7R IV has received a huge raft of improvements to ensure reliability and intuitive operation. Dust and weather sealing has been significantly enhanced, with improved gasketing for all buttons and ports. A deeper grip and improved button feel make for a more enjoyable shooting experience and more comfortable operation.
