Wide-Angle Prime for Nikon DSLR
Sigma's 24mm f/1.8 EX DG Aspherical Macro lens is a wide-angle prime designed for full-frame Nikon DSLR cameras. It also works on APS-C bodies where the field of view equals approximately 35mm. The large f/1.8 aperture suits low-light work and shallow depth of field. Two aspherical elements correct distortion across the 84.1-degree angle of view.
Suited to Environmental and Close-Up Work
Photographers needing a fast wide angle for landscapes, groups or reportage will find the 7.1-inch minimum focus distance useful for near-far compositions. The nine-blade diaphragm produces smooth background highlights. Buyers who want zoom flexibility or a longer telephoto reach should look at a different focal length. The fixed 24mm perspective does not suit every shooting style.
Straightforward Mount and Focus Operation
The lens mounts directly to the Nikon F bayonet without an adapter. A floating internal focus system keeps the front element stationary, simplifying filter use. Dual-focus allows instant manual override by turning the ring while in autofocus. The package includes a hood, front and rear caps, plus a carrying case. No firmware steps are required.

Questions about this item
What Nikon SLR mount does this 24mm f/1.8 EX DG lens require to function?
It fits Nikon F-mount DSLR bodies, covering both full-frame and APS-C formats, so any camera using that bayonet will accept the lens.
Will the 84.1° angle of view stay the same if I keep my APS-C Nikon body?
On an APS-C sensor the field of view narrows to roughly the 35mm equivalent, so the wide perspective changes while the lens optics remain identical.
How can I confirm the floating internal focus is operating at the 7.1-inch minimum distance?
Switch to manual focus, turn the ring until the subject at 7.1 inches is sharp, and verify the front element does not rotate or extend during the process.
