Panasonic S1R II Dynamic Range Test Results -

By admin, on March 25th, 2025

The LUMIX DC-S1R Mark II is a mirrorless camera from the LUMIX S series, announced at the end of February 2025. It is equipped with a newly developed 44MP BSI sensor and a processor that supports high-speed processing using L2 technology. It supports 40 frames per second continuous shooting and 8K 30p video recording. As an alternative to expensive stacked CMOS sensors, it has high-speed performance.

At the same time, it is significantly smaller and lighter than the previous model, and the selling price, at least in North America, is cheaper. Furthermore, it has a high-resolution EVF and a tilt + vari-angle monitor, but the body size is close to that of the S5II.

Key points of Panasonic S1R II Test Results

According to the Photons to Photos test results, NOISE REDUCTION is applied to RAW from ISO 6400 onwards, which results in higher test scores, but caution is advised if you value detail over noise. The results are very similar to DPReview’s studio scene test.
On the other hand, unlike the previous model, which applied noise reduction even at base ISO, it seems that the noise reduction process is not applied at low ISOs. If you are shooting stars, etc., it seems that there will be no problem if you keep the ISO up to around 5000.
While the peak values are lower than other high-resolution sensors, the difference in performance is not surprising, and in comparison, the results are better from ISO 6400 onwards (thanks to noise reduction).
