Sigma 50-100mm f/1.8 DC HSM Art Lens for Nikon F

The Sigma 50-100mm f/1.8 DC HSM Art Lens for Nikon F-mount combines a versatile telephoto focal length range with a fast and impressive design. Its bright f/1.8 constant maximum aperture ensures consistent low-light performance throughout the zoom range, while also providing precise control over focus placement for shallow depth of field and selective focus applications. The optical design incorporates low dispersion and high-refractive index elements to suppress aberrations, color fringing, and distortion, resulting in high clarity and sharpness. A Super Multi-Layer Coating controls lens flare and ghosting, enhancing contrast and color accuracy. The lens features an advanced Hyper Sonic Motor (HSM) and an internal focusing and zoom design for fast, quiet, and precise autofocus performance. Additionally, an integrated tripod collar provides stability when working with a tripod or monopod.

As part of Sigma’s Art line in the Global Vision series, this lens delivers outstanding optical performance, making it ideal for creative and artistic applications. It is designed for DX-format Nikon F-mount cameras, providing a 75-150mm equivalent focal length range.

Key Features:
– Telephoto zoom lens designed for DX-format Nikon F-mount cameras, offering a 75-150mm equivalent focal length range.
– Bright f/1.8 constant maximum aperture for consistent low-light performance and greater control over focus in selective focus techniques.
– Optical design includes three F Low Dispersion (FLD) elements and four Special Low Dispersion (SLD) elements, effectively reducing chromatic aberrations and color fringing. Additionally, one high-refractive index, high-dispersion glass element controls spherical aberrations for increased clarity and sharpness.
– Super Multi-Layer Coating minimizes lens flare and ghosting, contributing to contrast-rich and color-neutral imagery, even in backlit conditions.
– Integrated Hyper Sonic Motor (HSM) and internal focusing system enable quick and quiet autofocus. The optimized AF algorithm ensures smoother focusing performance. The HSM also allows full-time manual focus control by rotating the focus ring.
– Internal zoom and focus designs result in a compact lens length during operation, providing intuitive and controlled handling as well as faster performance.
– The rounded nine-blade diaphragm is constructed from durable, fluorine-coated polycarbonate and features a carbon feather film for smooth performance during fast continuous shooting rates.
– Constructed with a Thermally Stable Composite (TSC) material for precision and reliability in wide temperature variations. The brass bayonet mount improves mounting accuracy and rigidity.
– Fixed, rotating tripod collar offers increased stability when working with a tripod and integrates 90° click stops for easy switching between horizontal and vertical shooting orientations.
– The lens is compatible with the optional Sigma USB Dock, allowing fine-tuning of various lens characteristics and firmware updates.
