As a full-frame model, the new Carl Zeiss Otus 1,4/55, mounted on the Nikon D800, is categorically the highest performing standard-type prime in our database. When tested, it achieved the highest DxOMark score we’ve yet seen of 45 points and it attained a record Sharpness score of 29P-Mpix (out of a theoretical maximum of 36P-Mpix on the Nikon D800), prompting us to speculate that the Otus would achieve 30+ P-Mpix with the D800E.

When comparing the new Otus with the previous best performing fixed focal length lens in our database, the latest version of Nikon’s specialized high-speed portrait lens, the AF-S Nikkor 85mm f1.4G the Zeiss easily out-performs it. However, it’s also close to twice the price and a serious investment. Fortunately, it will serve double duty on a Nikon DX format DSLR with the equivalent field of view to a 85mm.

Best DxO Mark score ever measured:

The Carl Zeiss Otus 1,4/55 has the highest optical quality of any retrofocus 35mm format design to be assessed by the labs at DxOMark.

Highest sharpness score ever measured:

Prior to the new Otus, the lens with the highest sharpness score was the ultra-fast Nikon AF-S Nikkor 200mm f/2.0G ED lens, which the Zeiss has just beaten by one point.  Although that’s an excellent achievement, it demonstrates just how good that particular Nikon lens really is. Even the highly acclaimed Sigma 35mm f1.4 HSM A is still some way behind in sharpness, albeit with a excellent 23P-Mpix score on the Nikon D800.
