Sigma 4.5mm F2.8 EX DC Circular Fisheye HSM

Sigma 4.5mm F2.8 EX DC Circular Fisheye HSM

Price (MSRP): $1,400.00
TYPE: Fish Eye


The Sigma 4.5mm F2.8 EX DC Circular Fisheye HSM lens is designed for use with digital SLRs that use APS-C-size sensors. The lens is available with Nikon, Canon, and Sigma mounts. The 4.5mm lens has an angle of view of 180 degrees in all directions with all three camera brands, producing a circular image within the frame. The fisheye lens is well-suited to close up photography, with a minimum focusing distance of 5.3 inches, and maximum magnification of 1:6. The lens also has an f/22 minimum aperture; Super Multi-Layer Coating to minimize flare and ghosting; a Hyper Sonic Motor (HSM) for fast, quiet autofocus; and manual focus override via rotation of a focus ring. Gelatin filters can be inserted into a holder at the rear of the lens. The circular fisheye also incorporates Special Low Dispersion (SLD) elements to minimize chromatic aberration. Though availability details have not yet been announced, the Sigma 4.5mm F2.8 EX DC Circular Fisheye HSM lens will have a MSRP of $1400 when released.
