Fujifilm X-S1 Review - Sample Images: ISO Performance Review

Sections


At ISO 100 the Fuji X-S1produces sharp, noise-free images


ISO 200 is almost identical to ISO 100


At ISO 400 some slight softening has begin to
creep in, but you’ll need to go looking for it at 100% or more


By ISO 800 image softening is more visible, with increased noise in shadow areas


By ISO 1600 shadow detail has really begun to break down, though the image remains useable at smaller sizes


Noise and a softening of detail is easily visible at ISO 3200, even at smaller image sizes


Because ISO 6400 requires you to shoot at 6MP, the overall image size is smaller. Quality isn’t great either


ISO 12800 requires you to shoot at 3MP and the results are fairly terrible
