The Fuji X-Pro1 is capable of excellent image quality at ISO levels all the way to ISO 12800. Also, ISO 12800 in JPEG looks better than ISO 6400 in RAW (due to noise reduction applied on JPEGs), except there is a significant amount of detail loss in the shadows. Interestingly, the JPEG version of ISO 32 shots looks much cleaner in comparison. ISO 3200, on the other hand, adds more noticeable noise that looks significantly worse in comparison to ISO 1600 – shadow details are getting lost as a result.Īt ISO 6400 the amount of noise doubles throughout the image and much more shadow details are lost. ISO 25600, on the other hand, looks too muddy and washed for my taste.Īs we increase ISO, the amount of noise also increases – ISO 1600 only marginally increases noise over ISO 800. Still, ISO 12800 is very usable in my opinion, especially when down-sampled. Noise is apparent in the shadows (although noise reduction makes it look a little “muddy”) and more artifacts are visible throughout the image. Take a look at these:īoosting ISO to 12800 results in more noise and much more aggressive noise reduction by the camera. High ISO Performance “Boost” (ISO 12800-25600) – JPEGįuji X-Pro1 has two extra ISO “boost” levels – ISO 12800 and ISO 25600 for extreme situations. Whatever Fuji does with its JPEG processing is very impressive. Still, the performance at ISO 6400 is excellent. ISO 3200, on the other hand, adds a little bit of noise and here we can see the effect of noise reduction applied by the camera on JPEG images – clarity is slightly reduced as a result.Īt ISO 6400 some details get washed away and we are starting to see some artifacts here and there. Here is how the Fuji X-Pro1 performs at high ISO levels between ISO 16:Īgain, going from ISO 800 to ISO 1600 practically does not add any noise to the image, even in the shadows.
High ISO performance is a very important measure of sensor quality for low-light photography. High ISO Performance (ISO 1600-6400) – JPEG
