Sony A9 doesn’t edge out A7R II in ISO performance!

Sony A9 is really a massive camera, according to its sturdy and advanced specifications, but when Dpreview took it to the testing center Sony A9 shows a bit laziness in the ISO performance. Yes, overall, Sony A9 is powerhouse of techs; that is right, but compared to its own group member, Sony A7R II, its lowlight performance is slightly weaker (which is unobjectionable).

You should know that Sony A9 gains 75% pixels area compared to A7R II (Sony A9 – 24 MP, Sony A7R II – 42MP)) ,meaning the light gathering ability of A9 is more, but still noise is openly visible in the shot taken by this camera, which is considerably more than that of Sony A7R II.

SO 51,200 comparison of a7R II vs a9. Not much difference, though the a7R II does slightly edge out the a9. Normalized signal:noise ratio (SNR) measurements place the two neck-to-neck: 1.82 vs. 1.48 for the a7R II and a9 at the dark patches here, respectively. At ISO 25,600, the normalized SNR is exactly the same.
