Fujifilm X100S Review: Digital Photography Review

The X100S sees Fujifilm revisiting the concept, but while the external design is essentially unchanged, it's a very different camera inside. It uses a 16.3MP X-Trans CMOS sensor similar to that seen in the interchangeable lens X-Pro1 and X-E1 models, but now with on-chip phase detection promising much-improved autofocus speed. This is supported by a new processor, the 'EXR Processor II', which includes a new 'Lens Modulation Optimizer' function. According to Fujifilm this 'overcomes' lens aberrations such as diffraction and peripheral aberrations, and should give improved image quality at the largest and smallest apertures. The electronic viewfinder has been upgraded to a higher-resolution 2.35M dot display (from 1.44M dot); however this isn't the OLED unit used in the X-E1, but an LCD instead.
