The Sigma 4.5mm F2.8 EX DC HSM Circular Fisheye
A great circular fisheye lens is a fun and unique option for photographers who specialize in panoramics, landscapes, or even action sports. The Sigma 4.5mm EX DC HSM Circular Fisheye is a professional quality lens with a 180 degree angle of view, so it’s perfect for getting that distinct feel of a circular fisheye. The circular field of view gives you striking images that have an exaggerated perspective of a close subject and a distorted view of the surrounding background. These elements can really elevate an already cool shot of a live sporting event to really give an immersive feel, or a small nature detail in a largerlandscape.
