JUST as we've seen in many compact cameras before it, the Canon PowerShot G5 X has a 20.2-million-pixel BSI CMOS sensor. As we would expect, it's a solid performer. Being 1in, it's as big or bigger than that found in the majority of compact cameras, allowing for better signal-to-noise ratio compared to smaller-sensor compacts.
At low ISO sensitivity settings up to around ISO 800 there's plenty of detail with very little noticeable luminance noise, unless you are looking at pixel level. Detail starts to drop after ISO 1,600, and when reaching ISO 6,400 the pictures are obviously very noisy. While Canon's in-camera noise processing smooths most of it out, this is at the expense of much of the detail. However, to Canon's credit JPEGs do tend to give strong, attractive…
