ISO sensitivity and noise
At ISO 100 (which is only available in JPEG) the X-T10 gives an essentially noise-free image, with good rendition of fine detail and attractive colour (although highlights visibly clip). Switch to ISO 200, the lowest setting available in raw, and the image quality is still excellent but there’s more detail retained in the highlights.
Noise only really starts to have an impact at ISO 1,600, with shadow detail starting to block up a bit. From this point onwards it has increasing impact, but even ISO 6,400 gives quite acceptable results for less critical purposes. The top three settings – ISO 12,800 through to ISO 51,200 – are only available in JPEG, and give very marginal results. Indeed, the top setting is barely usable at all.
