Who is this lens for?

If you shoot night skies, Milky Way sessions, or sweeping landscapes with a Nikon F body, the Sigma 14mm f/2.8 EX HSM Aspherical gives you a genuinely wide field of view with enough light-gathering at f/2.8 to keep your ISO manageable in the dark. It's a rectilinear design, meaning architecture and horizon lines stay straight — unlike a fisheye. Buying it used makes a lot of sense here: this is a relatively simple prime that ages well mechanically, and the HSM motor keeps autofocus usable for those pre-dawn landscape moments when you don't want to be fumbling in manual. Pair it with a Nikon D750, D800, or similar full-frame body to get the full 14mm angle of view. If you're after a faster alternative within the same family, the Sigma 14mm f/1.8 DG HSM Art is worth a look as a comparison point, though it comes at a higher price point — used or new. The Samyang 14mm f/2.8 IF ED UMC Aspherical is another option that often comes up alongside this lens.
