The score of 97 points puts the Sony A7 IV camera to the 7th place in full-frame and MF sensors. This score is the same as Nikon D810 and Sony RX1R II, and the sensor performance is close to that of Sony A1 (98 points) and Sony a7R IV (99 points).
In terms of base sensitivity, Sony a7 IV has achieved good results in color reproduction and dynamic range, and the low light ISO has also been very good. High score of 97 points offers a combination of 25.4 bits color depth, 14.7 EV dynamic range, and 3379 ISO low-light score. More details about the Sony A7 IV sensor review after the break!
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.
