It’s real: Sigma 18-35mm f/1.8 DC HSM lens announced


The rumors were true: Sigma officially announced the world's first 18-35mm f/1.8 DC HSM zoom lens:

World’s first lens offering an aperture of F1.8 throughout the zoom range.SIGMA 18-35mm F1.8 DC HSM

The Sigma Corporation is pleased to announce the new Sigma 18-35mm F1.8 DC HSM, the large aperture APS-C format standard zoom lens.

What makes a standard lens ideal for you?

Certain important qualities are required, such as fast maximum aperture, versatility for snap shots, portraiture and indoor photography plus a good combination of a wide range of focal lengths in a compact design.

SIGMA 18-35mm F1.8 DC HSM is the first zoom lens ever to achieve a maximum aperture of f1.8 throughout the zoom range. It is a wide aperture, standard zoom-lens for digital single lens reflex camera's with APS-C size sensor's.

The lens has a focal range equivalent to 27mm - 52.5mm in a 35mm format and it can cover the angles of view of multiple fixed focal length lenses. This wide aperture, standard zoom lens enables the photographer to expand creative possibilities on any occasion.

    A 28-50mm in full-frame equivalency. For me, I’d rather have 30mm or 35mm prime, if that’s the zoom range. If this started at 20mm, even at f/2, it would have been much, much more interesting.

    MTF data are is missleading. Lpmm are not especificated.

    Looks fantastic for indoors and flash photography (weddings …).
    Great with D7100 or hopefully D400.
    Too bad it is a bit late on the market, but if the price is right could be a winner.

  • Azando

    Good stuff! This forces the user to commit to DX, which is not necessarily a bad thing assuming the format will stick around for another several years.

    Plus the fact that a manufacturer like Sigma is willing to release a product like this probably says something about the DX format and whether or not it’s lifespan is winding down. With or without a D400 (hopefully with) DX has not yet taken its last breath

  • Now we just need 10 or 12 mm wide angle DX prime and last hole in DX lenses lineup will be covered 😉

  • s1Lma

    Despite being very interesting pricing could be very crucial for this product,
    for instance if it cost more than 1000$ then one can be good served with d700 + 28-70, with all consequtive benefits of FF.

  • NRA Advocate

    There are good reasons why manufacturers like Canon and Nikon don’t build lenses like this, particularly at the price point Sigma is likely to set: Because they are too optically compromised. They don’t make the cut in terms of image quality.

  • Jonathan

    Looks like this lens would be excellent for concert photography and other low light event photography. If these new Sigma lenses are as good as they look, we are all in for quite a treat!

  • it would be nice if the craze from this lens gets nikon’s dx juices flowing. #D4002013

    Hi all. I’m a keen photographer but not in technical sense at all. I currently have Nikon DX equipment but can somebody explain in simple terms why this lens appears to be so good? I have read all the comments on aperture and focal length etc. but I don’t understand what the fuss is about (cos I just don’t know!)?

    • Viktor_Suhov

      this lens has zoom capability and constant aperture hole 1.8, it is 1 exposure stop faster than usual 2.8 zooms, that means you can set your shutter speed faster (for example from 1/50 (2.8) to 1/100 (1.8)) and freeze the action better (if you need) or (if you dont) just get more light to the sensor and have brighter picture (with the same 1/50 shutter, but aperture would be 1.8)
      Hope this helps, but it is better to read nice book from experienced photographer=)

      • Lensbaby

        Thanks Victor. That’s good!

  • nikkor

    wow the whole experts feed back is just overwhelming 🙂
    any news when it’s going to be awailable?

  • TaToSiKon

    Nice. Hopefully they are working on a 50-135mm or 50-150mm f/1.8 now.

  • Jonny Gawler

    (warning, massive punctuation pedantry:)
    it had to happen eventually: the missing apostrophe! referring to this lens, thom hogan wrote

    “Now if we only had that ultimate (D400) DX body to put something like this on. Balls in your court Nikon.”

    it sounds like some kind of hilarious disrespect, like “i spit on your face” etc. Yeah Nikon – Balls. In. Your. Court.

    • Studor

      Eventually, Tom Hogan will work out that Nikon isn’t listening or have any interest in what he has to say.

      Why a guy who writes books on Nikon cameras to continually p*iss off Nikon is beyond me.

      When was the last time TH had a Nikon pre-productioned body or even a lens to review?

      Heck, even the likes of PNet are given Nikon stuff before the rest of us.

    I photograph mainly for documentary, editorial & news, and I was thinking ‘why would I want this lens?’ (Apart from the fact it’s a f/1.8 zoom of course) and would it replace the 17-55 f/2.8 I currently use as my wide zoom on my D7000? Then I thought: ‘Could be an interesting lens to use for video.’ Short zoom, f/1.8…. I think I’ll probably rent one for a shoot or two and see how useful it will be. I’ve a feeling it will be useful, and high quality… Sigma’s new ‘art’ series are definitely looking serious. I’ve been using their new 35 f/1.4 on my D800 and image quality wise it’s excellent – pairs really well with the high megapixel sensor and focuses quickly and accurately too (essential for the kind of work I do). If this lens is anything like that in terms of performance I think they’re on to a winner.

  • Does the focus ring spin during autofocus?

  • jake

    is this a FX or a DX lens ?
    I would like to get it if it is a FX lens.

  • Alaska

    What is the deal with 18-35 mm? If it is a lens that is Fx based meaning it will work on a full frame camera then it is a 16-35 mm lens. Got that. If it is a APC formatted lens to be fitted on a DX format camera then it should be a 16-35mm on that size and not a 27-52mm lens. Its false advertisement. Why can’t they get it right? In the end the question still is – does it have a wide angle of 16mm equivalent on the Dx body?
