Fujifilm X30 Review – Image Quality
Resolution
A close inspection of our resolution chart revealed the X30’s Raw files resolve 3000 l/ph at ISO 100, which drops off to around 2600 l/ph at ISO 1600 and 2400 l/ph at ISO 3200. Beyond this sensitivity, the X30 only shoots JPEGS, however this remains a strong performance from a 12MP 2/3inch-type sensor and puts it on par with the results recorded by the X20.
Dynamic Range
Due to the fact the X30 only records Raw files between ISO 100-3200, our dynamic range results aren’t quite as widespread on the chart as some of its rivals. At ISO 100, the peak dynamic range is a high 13.92EV, which reduces to 9.5EV at ISO 3200. The X30’s D-Range Optimiser helped to balance exposures in high-contrast conditions, but even with this switched off, it was possible to return a high level of detail to shadows and highlights using Camera Raw.
Noise
The X30 produces noise-free images at low sensitivity settings, with the first traces of luminance noise creeping in at ISO 400. Although noise is removed reasonably well between ISO 400-800 in JPEG files, fine detail at higher ISOs is lost in the JPEG smoothing process, so as a rule of thumb, it’s always advisable to shoot Raw for the ultimate quality. ISO 6400 and 12,800 should only be used in emergencies.
