This preowned Sigma DC 17-50mm F2.8 EX OS HSM for Nikon F S/n 13956775 is characterized by its versatile zoom range and bright design, the Nikon F-mount Sigma 17-50mm f/2.8 EX DC OS HSM Lens for Nikon F covers a wide-angle to portrait-length range and features a constant f/2.8 maximum aperture to excel in available lighting conditions. The optical design incorporates a pair of low-dispersion elements along with a trio of aspherical elements to reduce a variety of aberrations and promote greater sharpness and clarity. A Super Multi-Layer Coating is also used to suppress flare and ghosting for improved contrast and colour accuracy. Benefitting the optics, a Hyper Sonic Motor affords quick and quiet autofocus performance while an Optical Stabilizer minimizes the appearance of a camera shake for sharper handheld shooting. Designed exclusively for digital SLR cameras and incorporating Sigma’s original OS (Optical Stabilizer). The OS function offers superior Stabilization. Additionally, the lens is distinguished by its sleek profile, making it an ideal lens for walkaround and travel shooting.

A standard zoom lens is designed for DX-format Nikon F-mount cameras and provides a 25.5-75mm equivalent focal length range. Constant f/2.8 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth-of-field techniques.

Two F Low Dispersion (FLD) elements are featured in the optical design and help to reduce colour fringing and chromatic aberrations for improved clarity and colour accuracy. Three aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering. Super Multi-Layer Coating has been applied to individual elements to minimize flare and ghosting for improved contrast and colour accuracy when working in strong lighting conditions. 

Hyper Sonic Motor (HSM), along with an internal focusing design, realizes quick and quiet autofocus performance as well as full-time manual focus override. A minimum focusing distance of 27cm and a 1:5 maximum magnification ratio benefits working with close-up subjects. 

The optical Stabilizer system minimizes the appearance of camera shake to benefit from making sharper imagery when shooting handheld. The rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
