A large aperture standard lens delivering uncompromised performance
Incorporating the same advanced optical technology as Sigma’s award-winning 35mm F1.4 DG HSM lens, this high-performance, large aperture lens offers superb image quality in a classic 50mm focal length.
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.
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.
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.
Special Low Dispersion Glass (SLD)
Used in conjunction with aspherical lens elements, SLD glass helps minimize colour aberration and produce sharp, high-quality images.
