The Sony α7R III has been welcomed with open arms by photographers across the world, and the reviews are proving that it's making waves as a leading full-frame camera. The latest review comes from DxOMark's Angela Nicholson, who recently posted her results on the Sony α7R III's performance compared to Nikon's latest full-frame DSLR, the D850. After taking an in-depth look at the performance of all, Nicholson says the DSLR "meets its mirrorless match" in the new Sony α7R III.
First looking at color depth, Nicholson checks the color sensitivity of the α7R III at its lowest sensitivity setting. The α7R III measured at 26 bits – an excellent score. The tonal range results show that the α7R III also recorded a broader range of tones, about .5 EV better than the D850. When taking a look at dynamic range, the α7R III takes a .3 EV lead at around ISO 640 and grows to a lead of .7 EV by ISO 51,200.
"The Sony α7R III achieves an overall DxOMark sensor score of 100 points, the same as the Nikon D850. This makes it the highest-scoring mirrorless system camera to date, beating the α7R II by two points. Naturally, this means that the sub-scores are also very good, and the sensor can indeed capture wide dynamic range with good color, but it’s the Sports (Low-Light ISO) score that particularly impresses at ISO 3523. This is the fourth-highest value we’ve ever recorded — beaten only by the sensors in the medium-format Hasselblad X1D-50C and Pentax 645Z, and by the 12Mp full-frame Sony α7S II."
