We tested the Canon G5 X against three key rivals to give an indication of where stands in the compact camera rankings:
Sony RX100 IV: the latest version of Sony's terrific high-end compact camera which, like the G5 X, has a 1-inch sensor, manual controls and an electronic viewfinder.
Fuji X30: this Fuji compact has a terrific retro design and is now great value for money, but the sensor is smaller than the Canon's.
Panasonic TZ70: Panasonic's high-spec travel camera offers a manual controls, raw files, an electronic viewfinder and a huge zoom range – but this is only possible because it has a small 1/2.3-inch sensor.
We measure resolution using an industry-standard test chart and check the resolution at each ISO setting for both JPEG and raw files, and you'll find the results below:
(Please note: our charts start at ISO 100 but the base ISO of the G5 X is actually ISO 125.)
JPEG resolution analysis: It's a pretty close-run thing, but the Sony RX100 IV's resolution is just a little higher than the Canon's across the ISO range. The Fuji X30 and Panasonic TZ70 lag some way behind, due to their smaller sensors and lower megapixel counts.
Raw (converted to TIFF) resolution analysis: The raw data shows a very similar pattern, with the G5 X and RX100 IV well ahead of the X30 and TZ70. This time, though, there's nothing to choose between the Canon and the Sony for outright resolution. Both come pretty close to resolving power of a good DSLR or mirrorless camera.
