We’ve already compared the Otus 1,4/55 to its closest optical rival, the AF-S Nikkor 58mm f1.4 and when compared to the best of the rest it’s quite clear the Zeiss has superior optical quality. Although good performers in their own right, with both having better transmission and the Sigma with slightly lower vignetting than the Zeiss, neither model can compare in peak sharpness or consistency across the image field over the wider apertures.

As with AF-S Nikkor 58mm f1.4G, neither the AF-S Nikkor 50mm f1.4G nor the highly regarded Sigma 50mm f1.4 EX D HSM can compare is sharpness and uniformity at full aperture.
