The Sigma 50mm f/1.4 DG HSM A1 for Nikon is a professional-caliber, fast-aperture prime lens designed for Nikon F-mount cameras. Key features include:
Great subject-background isolation and low-light performance
Excellent image quality, clarity, contrast, and sharpness
Fast, smooth, and quiet autofocus with manual-focus override
Nine-blade rounded diaphragm
Fast f/1.4 Aperture Wide Angle. The combination of normal focal range and fast aperture makes this lens ideal for portraiture where subject-background isolation is needed. This also makes it a perfect choice for shooting in low light. Being a standard 50mm focal length, the Sigma 50mm f/1.4 DG HSM A1 is useful for just about any type of photography.
High-Quality Optics. As a part of Sigma’s Art lens line, this lens goes through Sigma’s rigorous A1 testing to ensure high image quality. It features a molded glass aspherical element to eliminate sagittal coma flare, vignetting, and color blur throughout the aperture range. Three Special Low-Dispersion glass elements correct for axial chromatic aberration while the Super Multi-Layer Coating minimizes ghosting and lens flare. All this is incorporated into a floating optical design that provides high-detail rendering and a 1.3-foot minimum focusing distance.
Hyper Sonic Motor Autofocus System. Provides fast, smooth, and quiet operation in a wide variety of shooting situations. You can also manually override the autofocus motor at any time by rotating the focusing ring, giving you quick fine-tuning ability.
