Sigma FP2 Image Quality Deep Dive: HDR by Default

DPReview's deep dive into the Sigma FP2 finds the camera sets its base ISO at 320, running roughly 1.67 stops below the ISO 100 base that Panasonic and Nikon use on the same sensor. The gap is not a quirk: Sigma is pulling in extra highlight data to generate true HDR output, not just softening JPEG highlight rolloff. Detail resolves close to the Panasonic S9 and Nikon Z6III, with the Z6III edging ahead, though DPReview flags that not all of Sigma's processing decisions work.
