So versatile, allowing the photographer the convenience of carrying one lens to capture wide-angle and telephoto shots. Because they're Sigma telephoto zooms, they are always compact, lightweight and deliver stunning photographs.

Sigma's Professional Telephoto Zoom Lenses
The 18-250mm f/3.5-6.3 DC OS HSM was designed specifically for APS-C format DSLRs, on which it provides focal lengths equivalent to roughly 27mm to 375mm on a 35mm camera – yet it’s just four inches long and weighs only 22 ounces. It will focus down to 17.7 inches at all focal lengths, for a maximum magnification of 1:3.4 (one-third life-size). Sigma’s OS (Optical Stabilization) lets you shoot sharp images handheld, even in low light, while the HSM (Hyper-sonic Motor) provides quick and quiet autofocusing.
 
The 50-500mm f/4.5-6.3 APO DG OS HSM was designed for full-frame cameras, but can also be used on APS-C DSLRs, on which it provides focal lengths equivalent to about 75-750mm. Like the 18-250, it offers Sigma’s OS stabilization and HSM autofocusing.

Also designed for full-frame cameras but very usable on APS-C DSLRs as well, the APO 70-200mm f/2.8 EX DG OS HSM and 120-300mm f/2.8 EX DG OS APO HSM are fast pro lenses featuring OS, HSM and FLD glass that provides excellent correction of color aberrations. All offer great value, are compact and lightweight and deliver stunning photographs.

Sigma Lens Technology

APO (Apochromatic )
In order to attain the highest quality images, the APO lens has been made using special low-dispersion (SLD) glass and is designed to minimize color aberration.

DC For Digital
These lenses are dedicated digital SLR camera lenses with an image circle designed to suit image sensors that correspond to APS-C size. In-house technology accumulated through the development of our digital SLR camera was used to optimize optical performance for our digital lenses. This is a high-performance lens series that fuses technology such as lens power layout and coating design with the know-how Sigma has built up over many years of developing interchangeable lenses for SLR cameras. By reducing the diameter of the image circle, Sigma has achieved a more compact, lightweight lens series.

DG For Digital
These are high-performance lenses optimized for digital cameras. They are ideal not only for 35mm digital SLR cameras and film SLR cameras but also for APS-C digital SLR cameras. They deliver superior image quality by correcting for all types of aberration, especially distortion, and they have high-resolution capability because they minimize chromatic aberration of magnification, which is particularly a problem for digital cameras. What's more, these lenses incorporate optical designs optimized for digital cameras and Sigma's own Super Multi-Layer Coating technology, so they reduce flare and ghosting due to reflection between the image sensor and lens surfaces, and they provide high contrast and a wide range of tone. They provide enough peripheral brightness with little vignetting.

EX Lenses
With uncompromised design ideas and high-level optical technology and handling, these lenses, which are Sigma's representative lenses, meet the requirements of photographers at the highest level.

HSM (Hyper-Sonic Motor)
These lenses are equipped with a motor driven by ultrasonic waves. The motor makes high AF speeds and quiet shooting a reality.

OS (Optical Stabilizer Function)
This function utilizes a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating camera movement when shooting by hand held camera.
