"The 12-megapixel 2/3-inch EXR-CMOS sensor at the heart of the XF1 puts in a solid performance in the DxOMark Scores, ranking 12th overall for compact and high-end compact cameras. That said, despite the slightly larger sensor, it only boasts roughly the same image quality as competitors, such as the Nikon P7700, Olympus XZ-2 iHS, Canon PowerShot S110, and Panasonic LX7.
While these competitors achieve their best scores at the lowest ISO, the XF1 is a little stronger through the sensitivity range. The relatively small sensor compared to APS-C or Micro Four Thirds sensors however mean compact like this are always going to struggle with noise, and with a Low-light ISO score 199 ISO the XF1 struggles to achieve good image quality at higher sensitivities."
