Press release:

Sigma Corporation’s New, Optically Stabilized 120-300mm F2.8 Now Shipping in US

Fast, fixed aperture telephoto zoom is ideal for sports and wildlife photographers

RONKONKOMA, N.Y., June 1, 2011 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world’s most impressive lines of lenses, cameras and flashes, has announced that its updated 120-300mm F2.8 EX DG OS APO HSM is now available for purchase in the U.S. for the MSRP of $4,700.

The upgraded version of the Sigma 120-300mm F2.8 EX DG OS APO HSM will replace its predecessor as the essential Sigma lens for sports and wildlife photographers. The fast, fixed-aperture telephoto zoom will now feature some of the company’s new “F” Low Dispersion (FLD) glass elements and a splash-proof design which protects from “water spattering” as buttons and connections benefit from O-ring sealing connections to prevent dust and water getting inside the camera body. It also boasts Sigma’s proprietary Optical Stabilizer (OS) system, which will enable handheld photography and the use of shutter speeds approximately four stops slower than would otherwise be possible.

"This lens is a must-have for sports and wildlife photographers," said Mark Amir-Hamzeh, president of Sigma Corporation of America. "Think of this as a prime 300mm F2.8 in terms of its ultra-high resolution, with the added bonus of it being an F2.8 constant-aperture zoom lens that allows the photographer to recompose the scene anywhere from 120mm to 300mm without having to change their capture position. There's really no other lens like it."

The versatile lens is designed for use with full frame digital SLR cameras but may also be used with smaller APS-C size sensors with a corresponding effective increase in focal length to approximately 180-450mm with most cameras. The Hyper Sonic Motor (HSM) ensures quiet and high speed auto focus, while allowing full-time manual focus override. The maximum aperture remains constant at F2.8 throughout the entire zoom range. The addition of the optional Sigma 1.4x APO teleconverter effectively makes this lens a 168mm to 420mm F4.0 lens. Adding the Sigma 2x APO teleconverter makes this lens a 240-600mm F5.6 lens (full autofocus operation is possible using the Sigma 120-300mm F2.8 EX DG OS APO HSM and either the 1.4x APO or the 2x APO teleconverter in Sigma, Canon and Nikon mounts).

One SLD and two FLD glass elements, which are comparable in optical performance to fluorite glass, provide maximum correction of chromatic aberrations. The super multi-layer coating reduces flare and ghosting, and the lens design incorporates an inner focusing and inner zooming system to ensure sharp images throughout the entire zoom range. Improved optical performance provides excellent correction of sagittal coma flare and ensures ultra-high resolution, comparable to a fixed focal length lens.

    OMG OS system !

    • Global

      Normally, many Sigmas don’t work well on future Nikon bodies, so they have to be updated. If Sigma loses the court case, then Sigma-OS won’t be supported on future Nikon bodies.

      That’s the rumor.

  • SLD and two FLD glass elements, which are comparable in optical performance to fluorite glass

    This could also be interpreted as:

    1 FLD = 1 fluorite
    1 SLD + 2 FLD = 1 fluorite
    2 FLD = 1 fluorite

    Sounds to me like it’s the latter… because Canon themselves say that using 2 Canon UD elements gives similar correction to 1 fluorite. So FLD must be like UD or Super UD at best.

    Everyone claims they have some glass that’s fluorite-like in performance but fluorite is too hard to beat:

    The only real problem with fluorite (cost aside) is its low refractive index, which reduces its usability in mass-produced UWA lenses.

    Hopefully Sigma’s 12-24 II has even better performance with this new FLD stuff.

      When you have lens elements of all the same dispersion, the chromatic aberration is linear, only one wavelength at a time is in focus and the wavelengths to either side will be linearly defocused.

      When you have two different types of glass (with different dispersions), you can (if you do your optical homework), make an achromatic lens. Two wavelengths will be brought together in focus at the focal plane, and the defocus curve will be second order (a parabola). Most camera lenses are of this type and manufacturers don’t advertise the fact that they use two types of glass in these lenses (crown and flint glass).

      Three types of glass with different dispersions allow apochromatic design, three wavelengths in focus, and a third order defocus curve.

      Four (most you will see in any camera lens I know of), will allow the super-achromat, with four wavelengths in focus and a fourth order curve.

      The greater the difference in the dispersion of the different glass elements you use, the wider you can spread the in focus wavelengths, and the greater chromatic aberration correction you can achieve. Fluorite has very low dispersion, and is therefore very useful for correction of chromatic aberration. Sigma is advertising that their FLD glass has a similar dispersion to fluorite, therefore each FLD element is like a fluorite element (true or not, I dunno, but their 8-16 with a bunch of FLD elements is getting pretty rave reviews for a insaneo-wide lens).

        you two need to do less talking and more picture taking.

        • Dunno, I found it interesting.

          I just hope the OS is better than my Sigma AF 120-400/4.5-5.6 APO DG OS

  • longzoom

    This lens is already tested on PZ, Canon section. Really top one.

  • X101

    too expensive for SIGMA

    • Global

      Before even testing, based on Sigma past quality, you would guess what?

      50/50 chance of being Sharp. And 50/50 chance of Back-focusing.

  • Edward RNLMC retired

    Sorry Nikon this is going to be my new zoom lens but keep my hart on Nikon bodies D200 and on going the tests on the net are oke waiting only for hard copy in magazine somewhere.

  • too bad i have a canon 100-400 mm sigma is making interesting zooms

  • Thom Rockwell

    If Sigma can do it, then how come Nikon can’t make something similar?? I don’t get it

    • Global

      Because its weight is: 7 Pounds (2.95kg)!!
      And it has a 105mm Filter Size!!

      It makes the 70-200VR II seem like a light-weight by comparison!!
      TWICE as heavy.

      However, if you absolutely need 300/2.8, then for $3000 ($500 bucks more than the 70-200VRII), this is a real steal. Especially considering 300/2.8 primes weigh 6.5lbs and cost about $5,000.

      What I want to know — is when is Sigma going to make a 400-600mm/4 OS to pick up where Nikon drops off.

    • Snyggast

      Because it won’t allow Nikon to milk your bank account. If you’ve been using Nikon for a while. You’ll know what I’m talking about.

  • Weight – 3kg?

  • Nikon and Canon already have 80-400mm zooms, but they aren’t 2,8 glass. Honestly, it is a great idea to have such a lens, but 3kg is a bit big. Still, primes at 2,8 are massive, too. I’d like to hear from people who actually use it for sports rather than just shot in a lab and then take to the streets.

  • Leaking Starfish

    Be a great lens if it’s sharp, the autofocus doesn’t hunt, the colors are not all screwed up and it doesn’t fall apart.

  • I have the non OS version and it is awesome. Sharpest at f5.6 but can still outresolve my 5dII at 2.8 the whole way through the focal lengths. Definately recommended. I have seen in Australia two of these ever selling second hand, the first one sold for near to RRP, the second I bought for $1800. While there are not many of these, those that have them love them. I’m a fit 21 year old male, the weight is ok for me up to a couple of hours but I wouldn’t recommened trying to use it without a monopod for long periods unless you’re body building.

    Well i have to get back in training but love too do this for a lens and not anymore for the Marine corps

  • anyone know if there are any sample images by this beast?

  • mack

    at that price it should take the photo’s by itself, Its probably one heck of a lens
    but put of my reach If it came in 3.4f-stop I’d be saving for it

    • MF

      $2,999.00 at Adorama and B&H
