Canon PowerShot G1 X Digital Camera Review$799.99
We detected very little chromatic aberration during our time with the G1 X, and this speaks volumes about the quality of Canon lenses. On rare occasions, very light blue or yellow fringing appeared around high contrast edges. This effect was worst at the maximum focal length, but with only a 4x zoom the problem isn't bad at all.
Barrel distortion is observable throughout the zoom range and we do appreciate Canon's decision not to compensate for this in software, thus keeping our files as free from alteration as possible. It's also worth mentioning how far Canon has come since the G12. The downgrade to 4x serves the G1 X well, resulting in a roughly 33% decrease in distortion.
