Purpose and audience

The SIGMA 50-100mm f/1.8 DC HSM Art is a zoom lens built for APS-C Nikon DSLR bodies. It covers three popular short-tele focal lengths — 85mm, 105mm and 135mm equivalent — while maintaining a constant 1.8 aperture throughout the range.

Who this suits and who it does not

The lens suits portrait, event and video shooters who want prime-like sharpness at 1.8 without swapping glass. It does not suit photographers needing wider angles, longer reach beyond 135mm equivalent, or full-frame coverage.

Compatibility check

Verify your Nikon body uses an APS-C sensor and accepts DC HSM mount lenses. Confirm that autofocus and aperture control function with your specific camera model before ordering.

Questions about this item

Does this lens require a DX-format Nikon DSLR body to work as intended?

Yes, it is designed for APS-C DSLRs and its 50-100mm focal range equates to a 75-150mm field of view on those bodies.

Will it autofocus on an older Nikon DSLR that lacks a built-in focus motor?

Yes, the HSM (Hyper Sonic Motor) inside the lens drives autofocus independently of the camera body motor.

How can I confirm the aperture stays at f/1.8 throughout the zoom range?

The lens reports a constant f/1.8 value to the camera at every focal length from 50mm to 100mm.
