Canon PowerShot G1 X III lab tests
We've pitched the PowerShot G1 X Mark III against four interesting rivals, which are not necessarily in the same category on the surface but which we think are definitely worth considering as a second camera. They are Canon's own PowerShot G5 X, the Fujifilm X100F and the Olympus PEN-F.
The G1 X III doesn't deliver the most accurate colours of the four cameras we've compared, but it's better than the G5 X and not bad in absolute terms. Its consistently reliable auto white balance and natural-looking colour rendition are a bonus in real-world shooting.
It's all about the sensor size. The PowerShot G1 X Mark III and Fujifilm X100F have APS-C sensors and deliver much lower noise levels, especially at higher ISO settings. The PEN-F holds up pretty well, but the G5 X and its 1-inch sensor quickly falls behind as the ISO increases.
While noise levels and sensor size tend to be closely linked, dynamic range is harder to predict. The three larger-sensor cameras (including the PEN-F) offer similar dynamic range at medium-to-high settings, where the PowerShot G5 X starts to drop back, the G5 X is actually the best at lower ISO settings.
