Since telephoto zoom lenses are often used under very challenging situations, this model has crystalized all the possible qualities and features to achieve the best optical and action-capture performance. While combining high portability and durability, this high-performance hyper-telephoto zoom lens from our Sports line offers outstanding rendering capabilities. Its versatility provides better flexibility for wider shooting scenes, and the high-performance definitely stimulates photographers' artistic expression.
1. Achieves the best optical performance that embodies the product concept of our Sports line
By incorporating excellent optical glass elements, it minimizes chromatic aberration and achieves class leading image quality.
This lens incorporates 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, and 3 SLD (Special Low Dispersion) glass elements, and compensates for color aberration at the utmost. Chromatic aberration in particular, which could be visible especially towards the telephoto-end even when stopped down, is corrected by the optimized design of glass elements including FLD lenses.
2. High-end model with enhanced durability.
Dust-proof and splash-proof construction
It is Dust and splash-proof, and designed for higher durability. It is able to meet the demands that professional photographers would require in challenging shooting conditions, such as in the rain.
Zoom lock switch can be set at any focal length
The new zoom lock switch enables the zoom ring to be locked at any focal length. It can be fixed at the photographer’s desirable focal length, which allows stable shooting whether the lens is positioned upward or downward. It also helps during long exposure photography.
Water and oil-repellent coating ensures pleasant photography experience
With Coating Without Coating
Manual override incorporated to make two full-time manual modes switchable
In addition to AF/MF, MO (Manual Override) is incorporated as one of the options of the focus mode switch. By setting it to the MO position, it switches to manual focus by rotating the focus ring even during continuous AF. With AF position, standard full-time manual focus is available. Using the optional SIGMA USB DOCK, it is possible to adjust the MO position’s sensitivity to switch to manual focus.
Newly designed tripod socket enables desirable fixing
The tripod socket is newly designed since hyper-telephoto zoom lenses like this one which has 600mm telephoto-end often need a monopod or tripod for shooting. While ensuring that the tripod socket is large and stable, it’s possible to click the position at every 90゜to make the change of shooting position from and to vertical and horizontal much easier. By attaching the supplied strap, the lens can be carried safely without putting unnecessary pressure on the mount of the camera.
* Tripod socket cannot be detached from the lens
Offering excellent usability as a straight zoom
This lens is optimized to allow the lens front to expand/contract smoothly in order to immediately adopt without adjusting the holding position, even to a sudden change in angle-of-view. The lens front is designed to ensure easy handling in such situations.
3. High action-capture performance that enables any photographer
with high demands to get the exact shots they want.
Accelerometer enables panning photography both
in vertical and horizontal position
The OS (Optical Stabilizer) function using an accelerometer has been incorporated to ensure high accuracy. OS Mode 1 is suitable for general photography, and Mode 2 is ideal for panning shooting for motor sports etc. With Mode 2, the accelerometer works effectively to minimize blur while shooting by detecting whether the camera is positioned vertically or horizontally.
* This lens cannot be used on film SLR cameras with the exception of the Nikon F6, Canon EOS-1V.
* Effect of Mode 2 is limited to panning shooting in horizontal direction.
Quiet and Fast AF
The HSM (Hyper Sonic Motor) ensures high speed and quiet AF as well as full-time manual focus override by rotation of the focus ring. With the enhanced AF algorithm, smoother AF is achieved. The full time manual, which offers further adjustment after focusing with AF mode, is possible. By using USB Dock, you can change and adjust the AF speed at your convenience.
4. Customization and flexible adjustment for convenience or a specific purpose is possible
SIGMA USB DOCK - Customizable to your needs
Customization including firmware updates, focus adjustment, setting of full time manual operations as well as adjustment of the timing to switch to MF when rotating the focus ring is available with the optional SIGMA USB DOCK, by connecting it with the dedicated software “SIGMA Optimization Pro” on a computer. With this lens, custom mode that can be set depending on the photography situation is available by switching it on the lens. Through custom mode, it is possible to set AF speed, focus limiter where desired focus range can be adjusted, and OS where one of the patterns for optical stabilizer can be selected from “Dynamic View Mode”, “Standard” and “Moderate View Mode”.
5. Compatible with the newly developed tele converters.
AF is effective up to F8
Tele Converters that are newly designed to match the new lens line-ups (optional, planned to be released in 2014) can be attached. The addition of SIGMA’s TELE CONVERTER TC-1401 or TELE CONVERTER TC-2001 produces a MF 210-840mm F7-9 hyper-telephoto zoom lens or a MF 300-1200mm F10-12.6 hyper-telephoto zoom lens respectively. In addition, when SIGMA TELE CONVERTER TC-1401 is attached to cameras that are compatible with AF at F8, it is possible to shoot with AF.* When shooting subjects with low contrast or luminosity value, focus may not be spot on the subject.

With these lenses, fast-moving subjects even at distance can be well captured. This high-performance line also offers a variety of functions to aid the photographer in challenging conditions and scenarios. Besides sports photography, these lenses are also perfect for nature shots featuring birds and wildlife, as well as aero photography, trains, motor sports photography and portraits. Another major feature of our Sports line lenses is their wide range of customization options: using the dedicated software, all sorts of settings can be tailored to the personal preferences of the photographer.
[SIGMA GLOBAL VISION]
SIGMA Global Vision” - SIGMA is working on its full renewal of the products, and the new lens lines share all the following elements.
Evaluation with Sigma's own MTF measuring system “A1”
We used to measure lens performance with an MTF measuring system using conventional sensors. However, we've now developed our own proprietary MTF (modulation transfer function) measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of our quality control inspections. The SIGMA 120-300mm F2.8 DG OS HSM will all be checked using this “A1” before they are shipped.
