DxOMark Published Sony a7 IV Sensor Review: 97 Points

Posted on by

DxOMark has completed their full review and test results of the new Sony a7 IV – The Sony a7 IV mirrorless camera achieved an excellent overall DxOMark sensor score of 97 points, with a combination of 25.4 bits color depth, 14.7 EV dynamic range, and 3379 ISO low-light score.

Sony a7 IV Key Features:

  • 33MP full-frame Exmor R back-illuminated CMOS sensor
  • BIONZ XR image processing engine
  • 10 fps continuous shooting with AF tracking
  • Recording in 4K 60p 10-bit 4:2:2 with full pixel readout
  • 759 phase-detection AF points with up to 94% coverage
  • 3.68 mega-dot Quad-VGA OLED viewfinder
  • 3-inch vari-angle touch-screen LCD monitor
  • MI shoe w/ digital audio interface 
  • Long life Z-battery extendable via USB Type C 
  • External flash control from camera

Conclusion from DxOMark:

As the 24 MP BSI-CMOS full-frame sensor equips the out-going Sony A7 III, and the majority of Sony’s rivals at this level, the new 33 MP BSI-type CMOS in the Sony A7 IV will also probably appear in forthcoming competitor’s models, so the results are doubly interesting.

While the new sensor doesn’t perform a lot differently from the outgoing device, there has been a useful increase in the overall pixel count of 37.5% (albeit a 16.8% increase in linear pixel count on the long-edge). This may appear somewhat incremental, but when combined with the various improvements in stills and video features, the new Sony A7 IV is an incredibly well-rounded hybrid and a highly attractive option for all sorts of genres.
