Sigma DC HSM Lens for Nikon Standard SLR Cameras 18-35mm F1.8 F-Mount APS-C

The shallow depth of field of F1.8 allows you to blur the background, expanding the freedom of your photography. It covers the angle of view of several large-aperture prime lenses, from wide-angle to standard, and demonstrates high portability. Equipped with an ultrasonic motor (HSM) for quieter and faster AF, the AF algorithm has been improved for smoother AF. Full-time manual focus is also available, allowing you to fine-tune the focus simply by turning the focus ring after focusing. By adopting a super multi-layer coating, the occurrence of flare and ghosting is reduced, and high-contrast images are achieved even when shooting in backlight.
