Sigma 50-100mm f/1.8 Art DC HSM Nikon F camera lens

Telephoto zoom for APS-C Nikon F

The Sigma 50-100mm f/1.8 Art DC HSM is a constant-aperture telephoto zoom built for DX-format Nikon F-mount cameras. It covers a 50-100mm focal range with a bright f/1.8 maximum aperture throughout. The optical design uses a high-refractive index element and low-dispersion glass to suppress aberrations and colour fringing. Super multi-layer coating reduces flare and ghosting in backlit scenes.

Build and daily handling

The barrel measures 82mm in filter thread diameter and weighs 4.52 units, giving a dense, balanced feel on compatible bodies. A ring-type HSM autofocus motor drives focusing quickly and quietly, with full-time manual override available by turning the focus ring. The Nikon F mount uses an electronic aperture linkage, so aperture control is handled from the camera body. The lens ships with a petal-type hood that locks in place to shield the front element.

Compatibility check before ordering

This lens projects an APS-C image circle, so it is not suitable for full-frame Nikon bodies unless the camera is set to DX crop mode. Confirm that your camera uses the Nikon F mount and supports AF-S type autofocus, as the lens relies on an in-lens focus motor. The 82mm filter thread requires correspondingly large filters or a step-up ring for smaller systems. No tripod collar is included, so extended handheld shooting may be tiring for some users.
