Coming soon: Sigma 18-35mm f/1.8 DC HSM lens for Nikon mount


Update: the lens is now officially announced.

A quick update from PhotoRumors that I think (if true) will be of huge interest for Nikon DX shooters: Sigma is rumored to announce a new 18-35mm f/1.8 DC HSM lens for APS-C based DSLR cameras (27-52.5mm equivalent). That's right, a constant f/1.8 zoom lens! I initially did not believe this report, but the Czech website Fotoradce just published detailed specs of the upcoming lens:

  • Ultrasonic autofocus (HSM)
  • 9 aperture blades
  • Type A (Art), which guarantees quality materials, metal bayonet
  • Filter size: 72mm
  • Minimum aperture: f/16
  • Lens construction: 17 elements in 12 groups
  • Maximum magnification ratio: 0.23x
  • Weight: 810 grams, length: 121mm
  • Angle of view: 76.5 - 44.2°
  • Internal zoom and focusing
  • Minimal focusing distance: 28cm

    It’s extremely difficult to believe that this lens is real.

  • I agree, I did not believe it either at the beginning but now I think this is real.

    • If you’re right this will be a $1700.00 DX lens from Sigma or something? Hard to believe that will be a big seller for them.

    • I am now convinced it’s a PS job.

      Go look at the 35mm 1.4 stock images and compare. The lens hood back to the zoom ring is the same, bar the id info. The shadow highlight on the top curve of the lens matches too. The lens is different though and is a different colour and appears flatter.

      • If someone would make a fake, they would stop there, they will not go further to create a whole list of fake specs. At least this has been my experience with fake images in the past.

        • ok, but most of those specs seem like they would be pretty obviously the specs for a lens like this: Ultrasonic autofocus (HSM), 9 aperture blades,
          Type A (Art), etc.

      • Jordan Petram

        That is because both images would have been produced using KeyShot. Read recently that all Microsoft product images are created that way as are most automotive ads. No reason a lens wouldn’t be done the same way.

      • Eric Duminil

        Well, it could be a PS job (or KeyShot) but still be real.

      • Seems a slice of humble pie is in order. Apple please.

    • lorenzo

      Does Sigma have any factory or link with the Czech republic?

      I find a little strange that this ad appeared there first and not in Japan or the US – with all my respect for the Czechs.

  • pap911

    For me, it would be a zoom of the dreams.

    • Steve Hughes

      Oh no. I’m starting to salivate. Finally, the ultimate DX wide zoom. If this is real this lens could be so good.

  • No way… the filter thread would’ve been at least 82mm, not 72!

    • the 17-50mm 2.8 is 77mm, so basically 50mm/2.8=35/2… so basically it should be roughly the same, 72mm seems a bit small but who knows…

  • Nikonnut

    If its real…..WOW!

  • 800mm f/2.8 DX VR

    It will be EXPENSIVE.

  • Rui Nelson Carneiro

    This is a completely new lens, I wasn’t expecting, maybe cool if 18-35/1.8 + 24-70/2.8 + 70-200/2.8

    • Nikonnut

      Its aps-c though

  • Nikonnut

    Ive got the new Sigma 35mm 1.4 on my D600 and its a fantastic lens. If this lens is real and offers the performance similar to sigmas new “art” series then we’re in for something quite magical. Still its almost too good to be true. Rumored to be USD2000??

  • This is brilliant. Absolutely brilliant. I’ve been waiting for something like this for some time now. It will easily double, or more, the price (and weight) of everyone’s lens selection if this is implemented across more lens selections. Very interesting!

  • Still DX.

    • Global

      (DX is quite good these days). But the zoom range is quite quite poor — 28 to 50mm equivalency? I don’t think this is anybody’s “dream lens” — should at least start at 24mm — but it may very well be excellent quality. We shall see!

      • Amir Makar

        Dude, get your numbers straight: This is a 28-70mm equivalency on full-frame—at ONE POINT EIGHT. This lens would be perfect when teamed with a Nikon D7100 or Canon 70D/7DmkII. It would substitute all wide-normal primes on a full-frame camera, assuming its distortion isn’t bad of course.

        • Another Thought

          At the long end, 35 mm on DX is 35 times 1.5 or about 52.5 mm on FF. So this would be indeed equivalent to a 28-50 mm on FF.


          We’re talking Nikon here, so that’s 1.5x

        • Global

          What are you talking about Amir?? This is a 27-52.5mm lens in Full Frame 35mm standards — very ridiculous focal length. How can you say 28-70?? That’s not correct at all. Its basically a 28-50, which is very boring. You might as well just buy their 30mm or 35mm prime.

          • Global

            Also, isn’t DX (cropped) format is darker than full frame format? So isn’t this basically like an f/2.8 in Full Frame??

      • I know some DX lenses are good, but as I still use film (on top of my D90), I only buy FX ones.

  • coffcoff

    I don’t get it.
    It’s a fixed aperture zoom lens, it’s going to be expensive.
    Plus, it’s not a “usual” F2.8 lens, but a F1.8 one, this implies it will be very expensive. I’m ok with it, but.. DX? Seriously?
    Who on earth would spend so much money on a DX lens with that focal range?

    • Micah Goldstein

      “so much money” = ???

      Nobody knows what the price will be.

  • Snarfy

    I won’t be shocked to hear that this isn’t real, but it would be amazing if it turns out to be true!

  • Alex

    NOT REAL!!

  • Gonçalo Delgado

    dx? i don’t believe that sigma, if this is real, would mind about doing this for DX, just because 18-35 is better for full frame and it is almost physically impossible to do a 1.8 of this kind without an absolute expensive price..

    • RondoX

      18-35mm is pretty much a standard ultra wide to wide landscape range for FX users. I doubt a landscape lens would necessarily need a 1.8 max aperture, you usually see them in F/4s of F/3.5-5.6s. But if you give it to us, I’m sure we could put that 1.8 it to good use!

      However on a crop sensor its a 28-50mm equivalent. Wide to standard view is a very useful rage I think. I’m guessing that range is somewhat limited due to that 1.8 constant aperture. nevertheless, very useful! Especially considering Nikon has released the Cool Pix A with an 18mm lens, and has for whatever reason, yet to release an equivalent for their loyal DX users.

      With the D7100 recently released and no new DX lenses in sight, if this lens follows suite with the 35mm 1.4 in terms of quality, it will sell like hotcakes. The only issue is the price. But whatever it is, I’m sure it will be about HALF of what Nikon would charge.

  • Paul

    That’s one hot lens.

  • Holy WOW! Like many of you, I thought this was a misprint at first, 1.8 instead of 2.8. It’s rare that anything truly unprecedented is developed now (in terms of lenses anyway), this would be incredible and I’d be all over it in a heartbeat. I have the 35m 1.4 prime and it’s fabulous

    Remember back in the good old days of 2007 when Nikon made ‘wow’ products like this?

  • n11

    Now where’s that 70-200mm F/1.2 VRIII?

    • St. Prediction

      that will be released with medium format Nikon

  • Rayman 1

    No this is pretty serious and I think it is 100 % real !
    Its not so difficult to make a DC (DX) lens of that focal length and speed
    and that size… !
    Its about the same problem a T 2.5 and 28-50mm fullframe lens would
    pose… its not that impossible. Price is about what you pay for a 2.8 24-70mm
    This lens is very welcome and something that Thom Hogan was asking Nikon to make for a long time !

  • Sonikon

    IF this is really coming then I guess its safe to say that SIGMA is going for the CaNikon Jugular

  • niXerKG

    Did Sigma win anything from that lawsuit with Nikon? I know it was thrown out but Sigma has a fire underneath them and apparently a lot of R&D money to spend, really turning around their bad rep with QC especially with the 35mm f/1.4 DG.

  • Michael_Foley

    Mother of god, gimme gimme gimme.

  • marchellino

    If that was true I will bought it

  • Laurentiu Ilie

    16-35 f/2 would be much more interesting than 18-35 f/1.8.

    • Amir Makar

      For FX, perhaps.

      • Laurentiu Ilie

        No. 16-35mm on DX, means 24-50mm(FX equivalent) – much more useful than a 18-35mm (28-50 FX equivalent).

        • RondoX

          Just wow…
          First EVER 1.8 zoom in the history of SLR optics, and people are already complaining about what would be better….
          I LOVE NIKON RUMORS!!!!

          • Mr. Mamiya

            Indeed it is. On the other hand: As a DX lens, this will do exactly the same as a 27-50 f/2.8 lens on FX (in terms of focal length and DOF), so we are not exactly touching new photographic ground here. And to be honest, I’d still prefer a 24-xx zoom because that wide angle is more convenient. Exciting “first time f/1.8 zoom”, little impact.

          • Even I did not believe this one at the beginning… it took me few hours before I posted that rumor online.

            • Laurentiu Ilie

              Event if it is not 16-35, it is a great news for DX users! A big surprise from Sigma. Thanks for you work, admin!

          • desmo

            A f1.8 zoom that goes 28-50 in 35mm equiv.
            (Pretty much useless zoom range)
            Why not buy a 35 f1.8 DX Nikkor

  • GlobalGuy

    Finally, a “rumor” which we actually don’t know to believe or not, haha. Admin is so credible, we just assume he’s right. Should be “the Nikon Daily News”. ^^

  • SIGMA!!! Now were in the game! Good job!

  • ELK

    Now this is the rumor of the year(s)!

  • Pete Krest.

    It clearly states: “Společnost Sigma zítra představí revoluční zoomový objektiv
    Sigma 18-35mm f/1.8 DC HSM. Ano, čtete správně, není to aprílový vtip.”

    Which is:

    “Sigma company will introduce a new zoom lens
    Sigma 18-35mm f/1.8 DC HSM TOMORROW!!! Yes, you are reading correctly, it is not an April Fools.”
    So, we shall see tomorrow!!!

    • King of Swaziland

      Is tomorrow April 1 in the Julian calendar or something?

  • TylerVPhoto

    I imagine the reason it is DX only is because f/1.8 in a zoom would be way soft in the corners on a FX camera.. Very I need a DX camera lol

  • Spy Black

    I’d wish they’d make something similar in FX format.

  • Well, that was a fun read. Let’s hope it gets made!

  • nawab

    constant f/1.2?

  • leoparder

    The text in the middle does not follow the lines (curves) of the lens. This is photoshopped 100%. Pure fake.

    • Where?

      • one eye jack

        The “18-35mm 1:1.8 DC …” printed between the zoom ring and the small window that shows focus distance, on the 2nd image does seem not to follow the curved lines of the lens.

    • If it is a fake, it’s a pretty good one.

      • lorenzo

        Maybe it doesn’t count but I found a minor typo:

        Sigma calls it Hyper Sonic Motor (HSM) not Ultrasonic autofocus.

  • ohhhh if this is true!! I can assure you I going to be in my top 3 next lenses

  • Mark H

    Wouldn’t you expect a patent filing for the lens at least a few months before it’s released?

    • I don’t think anyone follows Sigma patents. On many occasions patents are filed after the lens is announced.

  • Rick

    I shoot full frame with 16-35 f/4 and 14-24, but still, I am super excited for DX users over this lens if it’s real. Nikon’s been slacking with their DX lens updates, and I am glad Sigma is filling that with their new A series. I have the 35mm f/1.4 from Sigma and it’s a fantastic lens for the price….can imagine how good this lens can turn out to be. Finally a fast constant aperture mid range DX zoom! Nikon is gonna get punished for being slacking

  • Rhonbo

    As a DX shooter I’m not too excited over this. 28-50 is a pretty narrow range, and 28mm is not very wide. At f 1:8 this is going to be really expensive but I can see indoor event / club / night time walk around shooters making good use of this lens.

  • Dave

    since when “1:1.8” means “f/1.8”?

    • EnPassant

      Since always!

      It describes how wide the maximum opening of the aperture is.

      For exemple a 50mm lens with a f/1.0 aperature has a 50mm opening which is the same as 1:1 of 50mm!

      This lens at 35 mm will have the opening (1:1.8)x35=19.4mm.

    • Writing f or T on the lens is the exception. Google “camera lens” and click Images.

    • seekthedragon

      Since the beginning. The f is only an abbreviation for “1/”…
      Ever wondered, why a bigger f stop means smaller aperture diameter? Check out that “1/” one more time.

  • Nikonuser

    Great for wide-angle fans (27-50). But personally, I’d be more interested in a 35-70/2.0 (or 24-50/2.0 on DX).
    And how big is that front element going to be?

  • Matt

    @Sigma: please now give us a smaller 50-150 DC OS or a 50-135 DC OS 🙂

  • Jonathan Ingram

    If it’s sharp at 1.8 it will be awesome. If not, there are already some great 2.8 lenses in this range…

  • Dave

    It says 1:1.8, not f/1.8, can anyone read?

    • King of Swaziland

      1:1.8 is f/1.8

      • Dave

        I suggest you get on Sigma’s or Nikon’s web site and look up what 1:x.x means….or let me save you some time, it’s called “Maximum Magnifications”, not “Aperture”.

        • King of Swaziland

          You’re an idiot.

        • Demere

          hahaha… u seriously make me laugh dude…

  • HotDuckZ

    It’s a fantastic lens, why Nikon not make it? 16-40 f/1.8 with 77mm filter +VR that lens will no one beat it!!

  • lmao


  • Dave

    The 1:1.8 stands for maximum magnifications.

  • Sebastian

    Let me complain even before it’s out: what we really need are fast short primes. What is so difficult to understand about this?
    This is too heavy, large, and won’t perform at max aperture.

  • Jon McGuffin

    Though I’m a quite happy and proud owner if the fine Art series 35mm 1.4, I second the thoughts here that a 27-52mm equipment is quite narrow and not the most useful range. I’d have preferred a similar “build” lens that have a 24-85mm equivalent range even if it were F2 or F2.8. That with a 77mm thread size would have had me a little more excited.

    Still pulling for Sigma all the way…

  • mknosens

    I was thinking about 35-50mm f/1.8 lens this morning!!!!! WoW.. it better be true!!

  • imbimmer
  • imbimmer
  • EnPassant

    Strangely nobody said it yet; This lens demands a “D400”!

    Maybe Sigma knows it and the 7DII is coming later this year?
