Just couple of months after the announcement of gorgeous Sigma 85mm F1.4 Art lens DXOMARK took it to their testing center to check the performance of this lens thoroughly. But before we give you the conclusion of DXOMARK we must say something about this lens. Well, you should know that the asking price of this lens is $1119, which is much expensive plus larger also that any other art lens but the favorable thing is that according to its performance the lens looks to be worth as its price is.
Now when DXOMARK compared it with Sigma 85mm F1.4 EX DG HSM lens mounted on Nikon D810… The 85mm F1.4 Art lens made a long jump and scored much more than its competitor (85mm F1.4 Art lens =50, whereas 85mm F1.4 EX DG HSM =37). Now from the Conclusion of DXOMARK we can loudly say that Sigma 85mm F1.4 Art lens is the best performer that incredibly outperforms Zeiss Milvus and highly expensive Otus lens’.
The Sigma has very high and homogenous sharpness, even wide-open, where high-speed lenses like this usually struggle. It reaches peak sharpness between f/2.8 and f/4, though it achieves optimum performance at f/5.6, with levels decreasing slightly on the Nikon D810 as early as f/8 due to diffraction.
Moreover, the uncontrolled Distortion is not a big issue with this Sigma 85mm Art Lens and it has very low lateral chromatic aberration.
With its Art series, Sigma has done much to improve its standing as a high-end lens maker. Until only recently, Canon and Nikon were on safe ground with their high-speed primes, but makers such as Sigma and Tamron (and Zeiss) are beginning to make inroads. While all the full-frame Art series lenses are excellent performers optically, the latest model in the range is also its best. It also happens to be the most expensive to date, but the $1,199 asking price seems reasonable. That it outperforms the Zeiss Milvus and outrageously expensive Otus equivalents probably says enough for most people — and that’s even before discussing the merits of autofocus versus manual on high-speed lenses like this.
