It looks like a classic rangefinder, yet it features Fujifilm’s latest EXR technology and, controversially, a fixed-focus, non-interchangeable lens. So has the FinePix X100 really been worth the wait? We find out
Noise, Resolution and Sensitivity
The 35mm equivalent view from the lens is wide enough to take in a range of subjects, from macro and portraits through to buildings and cityscapes, and delivers impressive sharpness
The quality of the image, in terms of noise and resolution, is perhaps this camera’s biggest sell, and ensuring that Fuji had got it right could have been one of the reasons this camera has taken as long as it has to come to market. The pairing of the lens with the sensor is intended to allow the X100 to control the distortions and aberrations more effectively and produce great-looking images.
The good news is that it doesn’t disappoint. Detail is impressive, reaching up to 24 on our chart from the raw file, and 22 from the JPEG. This is what we would expect from a DSLR with a 12-million-pixel sensor; however, both the Samsung NX100 and Sony NEX-5 offer more than 14 million pixels and have very similar resolving capabilities. At higher ISO values the resolution holds very well, remaining at 20 at ISO 6400. It seems slightly odd that neither the low ISO 100 nor high ISO 12,800 values can be accessed in raw mode, and it means we can’t see just how much noise is present, but the processing has certainly done a good job as the images still look very impressive and keep a resolution value of above 18.
In the JPEG files there are signs of luminance noise creeping into images from ISO 800, and becoming more pronounced at ISO 6400. From the raw images we can see that colour noise is present at ISO 3200 but the processing in the raw software, as with the JPEGs, has no problem removing it.
Resolution charts: These images show 72ppi (100% on a computer screen) sections of images of a resolution chart, captured using the Fujifilm X100. 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.
