Below are our standardised ISO test shots, starting with the Fujifilm X-E1's lowest standard setting of ISO 200, going all the way up to 6400, followed by the expanded settings of 12,800 and 25,600.
ISO 200 – 100% crop
ISO 400 – 100% crop
As well as delivering bags of detail, the X-E1 doesn't disappoint when it comes to ISO performance either. Up to ISO 800 images are smooth and devoid of any unwanted signs of image noise.
ISO 800 – 100% crop
At ISO 800 noise beginning to encroach ever-so slightly at ISO 800, but it's very subtle.
ISO 1600 – 100% crop
ISO 3200 – 100% crop
While image noise does become more apparent at ISO 3200, the level of detail rendered is still good.
ISO 6400 – 100% crop
At ISO 6400, results are still far more than acceptable, and though image noise is apparent, has a pleasing film-like structure
ISO 12,800 – 100% crop
Detail suffers at the extended ISOs of 12,800 and 25,600 with chroma noise becoming more prominent.
ISO 25,600 – 100% crop
