Fujifilm X-T1 review – Noise, resolution and sensitivity
The sensor puts in a solid noise performance, with barely a trace of luminance or colour noise visible between ISO 100 and 800. At ISO 1600, the X-T1’s in-camera processing begins to counteract the introduction of noise in JPEG images and does so without compromising the detail that is recorded. As you push up to ISO 3200 and 6400, a fine grain structure is apparent when images are inspected at 100% magnification, but again the processing that is applied to JPEG images helps to offset colour noise up to ISO 12,800. Users shooting raw can expect to see a minor drop-off in the level of detail that is recorded beyond ISO 1600, but images up to ISO 6400 are more than usable. As for the H1 and H2 settings, users should expect more aggressive noise and a waxier image appearance.
Putting its 16.3-million-pixel sensor to good use, the X-T1 resolves an equally impressive level of detail as the X-E2. At its base sensitivity of ISO 100, 30 lines per millimetre could be recorded, dropping to 24lpmm at ISO 6400. While these results can’t quite match our 32lpmm read-out from Nikon’s D7100 at ISO 100 (28lpmm at ISO 6400), the X-T1 is extremely close to APS-C-format DSLRs in terms of the level of detail its sensor is capable of reproducing.
These images show 72ppi (100% on a computer screen) sections of images of a resolution chart, captured using the XF 35mm f/1.4R lens set to f/5.6 . We show the section of the resolution chart where the camera starts to fail to reproduce the lines separately. The higher the number visible in these images, the better the camera’s detail resolution is at the specified sensitivity setting.
