The Sigma 4.5mm F2.8 EX DC Circular Fisheye HSM Lens creates an image that is a circular, curved, distorted view of reality when used on a digital SLR camera. One of the most unusual lenses a photographer can use as it produces a circular image within a black surrounding frame. It is ideal for landscapes and panoramic photography.
- For use with smaller chip APS-c cameras only
- The circular field of view produces striking images with exaggerated perspective of near subject and extreme barrel distortion of the surrounding areas
- HSM (Hyper-Sonic Motor) ensures a quiet and high-speed auto focus
