This ultra-wide diagonal fisheye lens delivers exceptional creative versatility for Nikon DX-format DSLRs. With a brilliant f/2.8 maximum aperture and hyper-sonic autofocus motor, the Sigma 10mm f/2.8 EX DC HSM captures an impressive 180-degree angle of view - delivering striking images with pronounced perspective distortion and exaggerated visual impact. The exceptionally close minimum focusing distance of just 13.5cm allows creative macro-style compositions, whilst the robust build quality, Super Multi-Layer lens coatings, and built-in petal hood ensure outstanding optical performance in varied lighting conditions. Whether you're capturing panoramic vistas, experimental close-ups, or architectural photography, this lens opens creative possibilities for photographers who think differently.
