Canon PowerShot G16 lens review: High speed, High IQ?By Kevin Carter - Tuesday October 29 2013 Lens Review
The lens achieves an above average DxOMark score overall of 12 points. Given the relatively low sharpness score, of 5P-MPix, the lens performs very well for this type.
Although, the bright variable aperture is one of the selling points of this particular lens, we’re unable to test the actual transmission values. However, it has consistent IQ throughout the zoom range, and has relatively low vignetting, distortion as well as good control of chromatic aberration.
