New: Sigma 18-200mm f/3.5-6.3 II DC OS HSM for Nikon mount


Last week Sigma announced a new lens for Nikon cameras: 18-200mm f/3.5-6.3 II DC OS HSM that will replace the previous version that was announced back in 2007. MSRP is expected to be $720.

Press release:

The Sigma Corporation is pleased to announce the release of the SIGMA 18-200mm F3.5-6.3 II DC OS HSM. This 11.1x high zoom ratio lens is designed exclusively for digital SLR cameras, incorporates Sigma’s original OS (Optical Stabilizer) function and offers a broad shooting range from wide angle to telephoto.

The SIGMA 18-200mm F3.5-6.3 II DC OS HSM is the successor to the SIGMA 18-200mm F3.5-6.3 DC OS/ HSM which was launched in June 2007. The lens is ideal for travel photography with a compact construction and length of just 87.7mm. This lens features FLD (“F” Low Dispersion) glass elements, which have the performance equal to fluorite glass, and SLD (Special Low Dispersion) glass elements providing excellent correction of color aberration. Aspherical lenses give excellent correction for all types of aberration and distortion. The Super Multi-Layer Coating reduces flare and ghosting, ensuring high quality images throughout the entire zoom range. Sigma’s OS (Optical Stabilizer) system offers effective correction of approximately 4 stops, enabling easy handheld photography. HSM (Hyper Sonic Motor) ensures quiet, high-speed auto focus and the inner focus system eliminates front lens rotation, making the lens particularly suitable for using the supplied petal-type lens hood and circular polarizing filters. The rounded 7 blade diaphragm creates an attractive blur to the out of focus areas of images.

* Sony and Pentax mounts do not incorporate Optical Stabilization.

Specification (For Sigma mount) 

  • *Lens Construction:18 Elements in 14 Groups
  • *Angle of View (for SD1):76.5-8.1 degrees
  • *Number of blades:7 Blades (Rounded Diaphragm) *Minimum Aperture (Wide):F22
  • *Minimum Focusing Distance:45cm/17.7in.
  • *Maximum Magnification:1:3.8
  • *Dimensions:Diameter 75.3mm×Length 87.7mm / 3.0in.×3.5in. *Weigh:490g (17.3oz.)

* FLD glass is the highest level low dispersion glass available with extremely high light transmission. The optical glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion. These characteristics give excellent correction for residual chromatic aberration (secondary spectrum) which cannot be corrected by ordinary optical glass and ensures high definition and high contrast images. * Vignetting will occur if the lens is used with image sensor larger than APS-C size or 35mm SLR, and APS Film SLR cameras. * For Pentax mount, auto focus will not be available on Pentax ist* series and K100D. * The appearance and specification are subject to change without notice.

    Hmmm, still f/6.3 at the long end. What I would like to know is why is it that only Nikon and Canon seem to be able to release one with f/5.6 at the long end, especially considering that they are essentially at the same price.

    • Mikycoud

      Yep, I was just gonna say that…
      Plus af accuracy is on the borderline above 5.6.

  • texajoe

    Whomp whomp whomp. Need more FX.

  • com

    Looks good (at least better). But will it autofocus with 6.3?

    • Don Pope

      At 6.3 it probably won’t focus with live view.
      This lens is too expensive. For $100 more you can get the Nikon or Canon versions which are better.

      • com

        This Sigma can be better than Canon version.


    I have been waiting for it for ages!

  • Why would anyone ever pay $720 for this lens when you can pay $790 for the newest Nikkor version, that bottoms out at F/5.6?

    Waste of R&D funds.


    • Sigma and Tamron lens usually retail at half of their MSRP. This will probably available on Amazon for $400.

  • David

    LAST WEEK NEWS. I Think the idea is that it is more compact and uses new type of glass that they are putting in their better lenses. Hopefully the street price will be cheaper than their own 18-250, it would be silly for them to price 18-200 above 18-250
    I am surprised that they updated 18-200 and not 18-250 and will carry both.

    • lolly

      As Mark above says, “Waste of R&D funds”

  • I would take a used Nikon version (VR I or II) over this any day.

    • David

      Not sure, I have gone through about 4 versions of Nikon 18-200VR over the years, on different bodies, and have always been disapppointed in 135-200mm range on that lens. Might as well get 18-135 or 18-105VR for much cheaper and lighter. If 18-200VR can be decently sharp at tele end, it might be an interesting solution, for travel (daytime of course) lens

  • Jim

    There should be two versions of this website. One for this consumer crap that no one really cares about, and one for quality gear actually worth caring about

    • Or, you could refrain from looking into and commenting on the posts you don’t care about.

      The rest of us that aren’t in this purely for the money and professional gear, the ones that enjoy photography as a hobby as well, and the ones that enjoy being in the world of photography and the accompanying gear as a whole will still enjoy posts like this. And it is a good one to read, as Nikon will be introducing 2 items with the D800 (which, I’m sure you’re interested in, unless only the D4 will do for you), and one is rumored to be a consumer DX lens. This could easily equate to their rumored 18-300mm lens.


  • DeepC

    Nikon and canon are horrible when it comes to sharpness and fringing. If this sigma is better with those area then I will buy it. Remember tokina 11-16mm is way to better than any nikon dx wide-angle.

    • Reilly Diefenbach

      As lomg as you don’t mind great big flare globules, you’re fine.

  • freeze

    I wish there was some indication of availability. Based on other sigma announcements it doesn’t look like this will be available for another 6 months. I’m surprised they announce so early. I’m very interested in this lens if street price is closer to $500.

  • Chris

    Sigma’s crazy, I’d take the Nikon 18-200 or Tamron 18-270 any day over this.

  • Red ring makes it look like a Canon lens. Meh.

  • Anonymous

    EWWWWW… it is still a sigma and stinks.

  • Mandrake

    Sigma EX or nothing. I put the value of this at $50. 😆

    • Bigus Dickus

      dont worry, it will find its new home on many “lens for free, camera for 200 more” actions in big retails. And of course mounted on 99% newbish DSLR purchases (“whoa what a zoom range awesome”)

    It is always easy to downgrade a new product and attack its pricetag, even before it is released and testet. If Sigma continues its recent top of the line aproaches i.e. 120-300/2,8 OS and 85/1,4, this new 18-200/”slow” very well could end up beeing the first serious multipurpose 11X-zoom.

    If You read the specs. this new lens contains Sigmas FLD ( more than one ! ) and not only SLD elements as in previous versions. The same new elements is incorporated in the new 120-300/2,8 OS, that seems to rival many primes in its range and sertainly outperform its predesessor – the non-OS 120-300/2,8 by a broad margin.

  • Moth Flopwell

    IF ONLY…Sigma knew how to make a lens…like their excellent Cameras!!! Wait a minute!!! lol

  • Carsten

    Perhaps THE lens nobody here cares about …

  • JBorg

    Regarding D800 sensor having 36 MPixel, did anyone consider as a possibility a Foveon like solution i.e. 12 MPixel x 3 colour layers as the possible step ahead of Nikon in this field?
    Actually I do not believe that a better signal to noise ratio can be achieved by higher density of pixels like 36 MPixel claimed, but I may be totally wrong.

  • collect

    To Carsten : Thank You for being open minded, until this new product has shown its wort in real life photography, or being just another addition to the endless lineup of 18-xxx mm walk-around lenses.
    If IQ ( supported by fluorite elemente, like in Canon L-series/Nikon ED or even Super-ED) is not setting a new standard in this league, the indicated price is close to a bad joke.
    I realy need a serious and lightwight travel-lens, so I can leave my downgraded (by numbers !) Nikkor line-up ( indeed not by weight ! ) 17-55/2,8, 105/2,8 VR and 200/2 VR – at home, and enjoy “lightweight photography” on the go.
