A great circular fisheye lens is an unusual and unique option for both pros and enthusiasts who specialize in panoramics, events, or action sports. The 8mm F3.5 EX DG Circular Fisheye from Sigma is a professional quality lens with a 180 degree angle of view, so it’s perfect for getting extreme forced perspective effects.
The 180 degree angle of view produces a cool circular image within a surrounding black frame. This lets you get truly creative by taking advantage of near and far perspectives that aren’t visible to the human eye. 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 larger landscape.
