DXOMark tests the Panasonic S1R
DXOMark published their Panasonic S1R results.
They gave the overall sensor score a tie with the Sony A7R III, at an even 100 and found it's color sensitivity to be exceptional.
Across much of the ISO range, the Panasonic S1R outperforms both the Nikon Z 7 and the Sony A7R III in color sensitivity, starting at a high maximum of 26.4 bits at a base of ISO 100, falling to around 15 bits at ISO 25,600.
Some noise reduction in the shadow areas in RAW files is evident at low ISOs (between ISO 100 and 200). We’ve accounted for this in our measurements (shown as “smoothed” on our graphs), but even at higher ISOs, neither the Sony nor the Nikon can really match it, except briefly at around ISO 800 and above ISO 25,600. Above that, all three drop below our 14-bit threshold for acceptable image quality.
The noise reduction at low ISO's is surprising, I wonder if there's a way of turning that off? The dynamic range though is a mixed bag, falling lower by 1 EV than the A7R III and never quite catching up at any ISO.
With such impressive color sensitivity, you might expect class-leading dynamic range. With a wide range of 14 stops at base (ISO 100) and a still-impressive 13 stops at ISO 200 (matching the Nikon Z 7 at those two settings), the SR1’s range is indeed very good. But if you look closely, the Nikon Z 7’s low base of ISO 64 has a marginally wider dynamic range of 14.6 stops (EV), and the Panasonic never quite matches the range of the Sony A7R III, remaining around 1 stop (1 EV) lower throughout the ISO range.
DXO finally concludes that the Panasonic S1R is;
Panasonic has chosen a new high-resolution 47.3MP CMOS sensor for the Lumix DC-S1R—one that challenges the class-leading sensors in the Sony A7R III and the Nikon Z 7. Intriguingly, it combines attributes of both of its rivals (with some nuances) and achieves near-identical performance results overall.
With its combination of high pixel count, low noise, and exceptional color sensitivity, the Lumix DC-S1R is likely to appeal to the most demanding studio photographers. And when conditions require it, its excellent dynamic range means the S1R should be a viable candidate for interior, wedding, and landscape photographers. Finally, its competitive price will also strongly appeal to keen amateurs who are looking for a solid all-rounde
