  • Hmmm, was hoping for 10mm. Oh well. 🙂

  • HD10

    Not very light but if the optics is good, this is good news.

    Nikon F-mount mirrorless FX please.

    • MB

      It seems those neutrinos do add up some mass …

    • If I’m not mistaken, the new Sigma 12-24 is DX.

      • Ned Gerblansky

        You’re mistaken.

        • It appears so–and I’m glad! I read it was APSC somewhere…looks like they were wrong. And now I want one!

          • CERO

            Im going to buy one as well, gotta complement my 24-105 and 150-600 sigmas.

      • HD10

        No its not DX. It fully covers 36mm x 24mm.

        • Danzig

          If it were Nikon/Zeiss, people would call robust, built like a tank or masterclass German engineering. I know it’s subjective, but weight hasn’t been an issue for most photographers until Sigma started its Art line.

          • HD10

            Not the case for me. I call a heavy lens as a heavy lens whether these be Nikkor or Zeiss. For reasons of weight, I added several Nikkor f/1.8 prime lenses to my Nikkor f/1.4 lenses primes when the lighter versions became available. I had considered the Sigma Art lenses but balked at the weight. The Sigma’s Art lenses have typically been heavier than their Nikkor counterparts. When one is carrying a 2nd body, multiple zooms and primes, every little bit of weight savings will help.

  • Glen

    What in the world is a neutrino coating? Considering neutrinos are almost impossible to even detect, let alone capture I am very curious as to what this is supposed to signify.

    • Julian

      Guess they couldn’t call it a nano-coat, so they went with something a bit cooler sounding (has to be a marketting decision)

      • Nyarlathotep

        Agreed, it is just a marketing name. The nano coating name is fairly silly too, but marketing departments certainly like to use those science buzzwords, proper usage be damned.

        • Captain Megaton

          The “nano” refers to the small crystallites used in Nikon’s optical coating usually called nanoparticles since their size is in the order of nanometers (1E-9 m). And branding goes it’s actually pretty legit as the technology was new and substancially different from previous coating materials.

    • Matt Comerford

      It’s a much cheaper form of coating vs Higgs or Quark.

    • disqus_hZsoUKhJQq

      It’s neutrino coating ’cause it can’t be detected by any available technology.

    • jstevez

      Next it will be Higgs Boson coating and more marketing bs.

      • CERO

        just settle for “Jesus” Coating.. because JESUS SAVES.

        You can later credit your coating for saving your front element from a fall.

    • TheInfinityPoint

      They’ll be using gluon coatings to combine elements into a lens group.

  • Julian

    I guess this is close to a full fish-eye then or?

    • Matt Comerford

      not really, per the above specs, FIELD OF VIEW
      126⁰ (diagonal)… nikon’s current 15mm f2.8d is 180 degrees.

      EDIT: oops thats for the sigma 15mm, not the nikon 16mm fisheye, but no, not a fisheye.

      • Nyarlathotep

        Most of the modern fisheyes are ~180 degrees. The 15mm Sigma and the 16mm Nikon and the 12mm Samyang are all 180 along the diagonal.

    • Nyarlathotep

      No Fisheye lens have uncorrected geometric distortions that project a different image than a rectilinear lens such as the 11 f/4 Irix. As Matt Comerford mentioned, it also has a narrower field of view than a Fisheye

  • Reilly Diefenbach

    Finally, a not 2.8 superwide :^)

  • Joe

    No weather sealing on the Blackstone but available on the Firefly? A bit disappointing that the more expensive, supposedly more robust model doesn’t have weather sealing :S

    • 120_300 OS for nikon

      the text is wrong Blackstone has weather sealing look at the video from sigma benelux at you tube.

      • Duncan Dimanche

        yeah they got that wrong 😉 the whole point of the more expensive one is its weathersealing

      • Joe

        ok thanks for that clarification. That sounds more likely. In that case I’m quite interested in the Blackstone, though want to see some reviews first. Wondering how it might compare to Sigma’s newly announced 12-24 f/4? I know they don’t cover the same focal lengths (and one is a prime, etc). I used to own a Nikon 14-24 f/2.8 which I regret selling but haven’t been able to justify buying it over again.

    • Well that’s the thing, plastic may survive a drop on concrete. Metal will bend and stay bent. Metal only feels more solid. Not that this is a rule–you could make a flimsy plastic design that would crack easily, and metal that is solid and won’t bend, and either could leave the actual glass vulnerable.

      But in general, OEM plastic designs have been more rugged.

      Either can be weather sealed.

  • Semaphore

    Is Irix a another brandname of Samyang, or are they a new actual Swiss company?

    • Nyarlathotep

      I am not sure. Seems the designers are Swiss, manufacturing in Korea, according to their website. I suppose it is possible they are leveraging Samyang production to do their work, but I can’t seem to find any info on it.

      That said, the design is definitely not Samyang. There lens designs (11mm, 15mm & 45mm) are different that the Samyang existing formulas.

      • HD10

        Concur. Still another indication that ownership is not Samyang is the seeming difficulty in marketing the Irux in the US and other parts if the world. The lens would widely and easily be available if this was Samyang.

  • Nikita

    Fixed hood = more bulky, not good for travel.
    No filter thread = more alternative stuff to buy.
    No AF = maybe okay in this FL.

    • Oompsy

      You don’t want the hood to be removable on such a super-ultrawide. The bulbous element should always be protected. Again, same thing thing with the filter. A super-ultrawide and filter usually don’t play well. A custom filter holder like for the 14-24mm from Nikon would be necessary. I do agree about the AF though. In this day and age it’s awkward to not have it.

      • Nikita

        removable hood and filter don’t seem to be a problem for Tokina 11mm 2.8 (that is, the DX 11-16 2.8). Everyone is always quick to say how there’d be no big size difference for UWA DX vs FX. If so, no hood and a filter thread please. OR… make 10mm 2.8 DX-ONLY prime – please.

  • Captain Megaton

    “neutrino coating”

    Giggles. Marketing clearly did not consult with engineering before going ahead with the naming.

  • Dino Brusco

    I am pretty dure this IRIX lens line will add some thrill to the actual competition. Everything on specs and look make me believe these are darn good lenses, optically speaking. I’d like to add that despite the hype for the huge depth of field, on modern DSLRs the biggest issue is probably the ease and the accuracy of focusing. DIGLLOYD already showed that also on those lenses a correct focusing does make a difference. Problem comes with cameras that can “only” offer you live view, slowing down things a lot, instead of investing also on better and larger focusing screens.

  • Kim

    If this is not a fisheye, how is 11mm rectilinear even possible on full-frame???
    The amount of correction needed in the borders/corners should render them useless sharpness/stretch-wise…
    If not: I’m impressed 🙂

  • Tamás Molnár

    WTF is neutrino coating?

  • I tried both the 11mm f4 and 15mm f2.5 at the Photokina yesterday, 11mm has nearly no coma / astigmatism wide open, distorsion seems to be controlled quite well for such an extreme angle. Colorcorrection CA and sharpness seems to be OK as well. Mechanical quality of the metal version (Blackstone) gets close to Zeiss, very close. The coating is excellent when shooting directly into the light, much better than my Samyang 14mm and even better than the Sigma EX fisheye 15mm. I used a D800. Both Irix lenses produce great sunstars like the Sigma15mm EX. I think that I well buy the 11mm f4 and 15mm version for time lapses -also for the astro-scapes. 11mm f4 image included at f4 (out off camera jpg, D800, at 20MP, active D-light extra high https://uploads.disquscdn.com/images/4f3e20a0907db723a15efecedf3ca672ec9f5fb06e0b3cc0d68a55618341e4c7.jpg

    Am very happy that Swiss and Corea is making the job that Nikon is unable to do. The old 14 – 24 has been overpassed by Canon 11 – 24 and Nikon is without reaction. Pay attention, am a fan of Nikon brand, am not here to charge this famous brand of anything, but as the commerce of Nikon brand is decreasing, facing to the solid Canon, am quite sad that my favorite brand is without reaction ; the 810A is a fabulous tool for astronomy, but the renewal of 14 24 is urgent. Some 11 24 VR would be pleasant ! But anyway, we will do the things with this 11 mm F/4 instead. Lack of AF is not really a big deal.. Love Switzerland !
