Dear All

For astrophotography I recently did some cooling tests with my Sony Nex-3N and my Fuji X-A1 (30s exposure, closed camera, ISO1600). From Rawdigger histograms, the Fuji seems clearly superior concerning noise behavior, however, the Sony histograms have only each 2nd/4th bin filled at identical RD settings. I attach the two histograms for comparison, does anybody have an idea what difference in raw format might lead to this effect?

Best regards

Thomas
