Conclusion

If the new 35mm F1.4 DG HSM lens is anything to go by, Sigma are definitely raising their game with the recent introduction of their three new lens ranges (Art, Sports and Contemporary). The Sigma 35mm F1.4 DG HSM is a fast and tack-sharp lens that exhibits low chromatic aberrations and very little barrel distortion. Vignetting at wide-open apertures is the only real optical issue of note, something that other fast lenses also suffer from, and stopping down to F/4 solves the problem altogether.

Build quality is also excellent, with the brass lens mount and sober all-black design adding to the high-quality feel, and Sigma have even generously included a very good lens hood and padded case. Focusing was very quick on the Canon EOS 6D that we tested the lens with, and manual focus over-ride at any time is a great feature.

Even the price of the Sigma 35mm F1.4 DG HSM is attractive, significantly undercutting rival lenses from Canon, Nikon and Sony. The only concession that it makes is the lack of any weather-sealing, something that the Canon and Nikon alternatives both offer. This is a relatively small concern for most photographers, though, so we can whole-heartedly recommend the new Sigma 35mm F1.4 DG HSM as a fast, well-built prime lens that delivers superb results. Essential!
