Sigma 135mm f/1.8 ART review (D. Abbott)

Sigma 135mm F/1.8 ART Review (D. Abbott)

Sigma 135mm f/1.8 Art: Amazon, B&H Photo, Digitalrev, eBay, Adorama, Canon USA

Sigma 135mm f/1.8 Art at a glance:

  • EF-Mount Lens/Full-Frame Format
  • Aperture Range: f/1.8 to f/16
  • Two FLD Elements, Two SLD Elements
  • Super Multi-Layer Coating
  • Hyper Sonic AF Motor, Manual Override
  • Rounded 9-Blade Diaphragm
  • TSC Material, Brass Bayonet Mount
  • Compatible with Sigma USB Dock

The Sigma 135mm f/1.8 ART must be an amazing lens, at least according to what reviewers say. It’s clearly another great lens by Sigma.

Canada based photographer and reviewer Dustin Abbott published an exhaustive review of the Sigma 135mm f/1.8 ART lens.

From the conclusion:

While the Sigma 135mm f/1.8 ART may not win any awards for being Sigma’s sharpest, brightest, or cheapest lens, I do think that in many ways it is Sigma’s most complete prime lens. Unlike some of the ART series, I didn’t find it clinical but instead appreciated the quality rendering from the lens. It does tend to skew white balances a little cool, and it doesn’t deliver the most deeply saturated colors out of the box, but the images process well. I have seen several excellent 135mm lenses for Canon/Nikon mounts in the past two years, including the Samyang/Rokinon 135mm f/2 and the outstanding Zeiss Milvus 135mm f/2, but both of these options are manual focus only. The Sigma 135 ART is the first 135mm lens to bring the excellence of modern lens design coupled with useful autofocus.

You can watch the 18 minutes video below for the final review, or you can head over to Dustin Abbott’s site if you prefer reading the review, and checking the many sample pictures.

Interview with Kazuto Yamaki, CEO of Sigma Corporation

Kazuto Yamaki

The new Sigma 135mm f/1.8

DPReview managed to interview Kazuto Yamaki, CEO of Sigma Corporation, at CP+ in Japan.

We all are obviously curious to learn about the latest lenses Sigma announced, especially about the 14mm f/1.8, a lens that once more shows the skills of Sigma’s engineers.

Some excerpts from the interview:

You’ve told me previously that you really want Sigma to make more wideangle lenses. Do you think you’re achieving that goal with the 12-24mm and new 14mm?

Yes, but I’m still not satisfied. I think we need to make more wide-angle lenses. A fast 14mm was one of the lenses that our customers were asking for. Most existing 14mm lenses are F2.8, so F1.8 was a challenge.

What have you learned, from making the Art series?

We’ve learned that some customers require exceptional lens performance. We believe that our mission is to make products that other manufacturers don’t have. If we just released similarly-specified lenses to existing models, we wouldn’t be contributing to the industry, or benefiting customers. So our Art series is meant to provide the best performance. Read the interview at DPReview.
