Sigma 10mm f/2.8 EX DC HSM Diagonal Fisheye - Sigma SA, Canon EF, Nikon F, Sony A, Pentax K Mount

The Sigma 10mm f/2.8 EX DC HSM is a diagonal fisheye lens specifically designed for APS-C sensor digital SLRs. It provides a 180-degree field of view (on most mounts), producing the characteristic distorted perspective associated with fisheye optics. The lens features a close minimum focusing distance of 13.5cm, allowing for exaggerated close-up compositions. The HSM motor provides fast and quiet autofocus, which is useful despite the inherently deep depth of field. Potential buyers should examine the front element for marks, as the protruding glass is vulnerable. SDS checks the rear gelatin filter holder for damage and ensures the autofocus mechanism is fully functional. The exterior 'EX' coating is inspected for signs of heavy wear or peeling. We also verify that the aperture blades are clean and move freely, as oil on the blades can affect exposure.
