Sigma 4.5mm f/2.8 EX DC HSM Circular Fisheye - Sigma SA, Nikon F, Canon EF, Sony A, Pentax K Mount
A dedicated circular fisheye lens for APS-C DSLR cameras, offering a 180-degree angle of view.
This circular fisheye lens is designed specifically for APS-C (DC) digital SLRs, providing a complete 180-degree field of view in all directions. It produces a circular image surrounded by a black frame on the sensor. With a fast f/2.8 maximum aperture and a Hyper Sonic Motor (HSM) for quiet autofocus, it is well-suited for scientific applications, panoramic photography, and creative architectural work.
Used examples should be inspected for the condition of the bulbous front element, which is susceptible to scratches as it cannot accept traditional filters. SDS checks the HSM motor for smooth operation and ensures there is no internal haze or fungal growth. The integrated petal-type hood should be securely attached and free from impact damage.
