We have received additional specs about the upcoming Sigma 17-40mm f/1.8 DC ART lens, which we remind you will be announced on June 17 along with the Sigma 12mmF1.4 as reported here.

The specs come from an anonymous source and no nickname has been shared in the message, but the way it was written I think it could come from the same anonymous source (with nickname), who shared the specs yesterday (and that source is accurate).

I share the rumor because I think it is the same source. But if that’s not the case, then I just published totally unverified rumor without any check from trusted sources. If that’s the case, take everything below with a grain of salt.

It’s now confirmed (THANKS), that the information comes from the same anonymous source with nickname, who has shared accurate information in the past.

In general a message to anyone: we also have a 100% anonymous Signal chat in which you can contact us.

  • Aperture ring, with de-click option
  • sealed against dust and splashes
  • Size: 115.9mm long, maximum diameter 72.9mm
  • 67mm filter
  • ⁠535 gram
  • Internal Zoom
  • uses aspherical elements made of SLD (Super Low Dispersion) glass
  • manufactured with advanced polishing technology to minimize chromatic aberration, flare, distortion
  • excellent sharpness from corner to corner already at f/1.8
  • HLA (High-response Linear Actuator) autofocus motor (fast, silent and accurate)
  • excellent control over focus breathing
  • announcement June 17
  • shipping in July

I guess Fujifilm shooters will love it that it has an aperture ring (at least so says the rumor).

Sigma 17-40mm F1.8 DC ART Specs Leaked – Internal Zoom and 535g Weight

A source—who contacts us anonymously but consistently uses a recognizable nickname, and who has shared accurate information in the past (THANK YOU)—has now passed along the main specs for the upcoming Sigma 17-40mm F1.8 DC ART:

  • uses aspherical elements made of SLD (Super Low Dispersion) glass
  • manufactured with advanced polishing technology to minimize chromatic aberration, flare, distortion
  • excellent sharpness from corner to corner already at f/1.8
  • HLA (High-response Linear Actuator) autofocus motor (fast, silent and accurate)
  • excellent control over focus breathing
  • Internal Zoom
  • weight: 535g

Now, Sigma made the Sigma 18–35mm f/1.8 DC HSM Art for APS-C DSLR cameras (launched in 2013), but that one weights 810 grams. So there is a substantial weight reduction with the Sigma 17-40mmF1.8 DC ART, and it even has more range on both ends.

I guess that’s something we can really look forward to.
