Aspherical Lens Elements
The use of aspherical lens elements allows for improved optical performance, a reduced number of component lenses, and a compact, lightweight lens design. Aspherical lenses provide high-quality, distortion-free images equivalent to those of a single focal length lens.
“F” Low Dispersion (FLD) & Special Low Dispersion Glass (SLD)
Used in conjunction with aspherical lens elements, FLD and SLD glass help minimize colour aberration and produce sharp, high-quality images.
DG Lens – Optimized for Digital Photography
DG lenses are compatible with the larger image circle of a full-frame DSLR camera. These lenses offer optimum correction of distortion and aberrations common to digital cameras. The advanced optical design eliminates flare and ghosting from the image sensor and improves colour balance. The non-vignetting construction ensures consistent edge-to-edge brightness and sharpness for superior digital image quality.
Floating Focus System
This focus system moves the lens groups to different positions, thereby minimizing the telescoping distance and the fluctuation of aberration at different shooting distances.
Hyper-Sonic Motor (HSM)
This lens uses a motor driven by ultrasonic waves to provide extremely fast, quiet and exceptionally accurate auto focusing. HSM is supported by Canon, Nikon and Sigma cameras.
Multi-Layer Lens Coating
Sigma’s premium multi-coating treatment reduces flare and ghosting and produces an optimum colour balance, improving image quality throughout the entire zoom range.
