DXOMark has completed their review of the Sigma 85mm f/1.4 Art series lens, and apparently they like it!
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.

That's definitely some amazing praise bestowed on the new king from Sigma. I love the Tamron 85mm f/1.8 VC, but this may have piqued my interest in trying out this Sigma 85mm lens.
