DxOMark completed their review of the new Canon EF 24-105mm f/4L IS II USM lens. Tested on the Canon EOS 5DS R, the Canon EF 24-105mm f/4L IS II USM lens gets an overall DxOMark score of 24 points, with a combination of 14 P-Mpix Sharpness, 4.4 TStop Transmission, 0.5% Distortion, -2 EV Vignetting and 5μm Chr.aberration – the new Canon EF 24-105mm f/4L IS II USM lens is a good performer!
“Looking past the scores for a moment, this new lens has very good-to-excellent sharpness across the image field at all focal lengths. It also has outstanding control of lateral chromatic aberration, excellent transmission, and relatively low distortion and vignetting.”
Conclusion from DxOMark:
If high sharpness is your only objective when buying a lens, then the scores achieved by the Canon EF 24-105mm F4L IS USM might be a little discouraging. Looking on the bright side, however, Canon has improved sharpness in the periphery at all focal lengths, even if that’s at the expense of some sharpness in the center. Whether that’s clearly better is open to debate, but in optical performance Canon can be praised for high transmission and for maintaining low levels of lateral chromatic aberration (fringing is lower than many high-grade primes).
Sure, we would have liked to see peak sharpness leap up, but then the price hasn’t sky-rocketed either. Optical performance is just one aspect of lens design, and this update still feels like more than just a step in the right direction.
