10mm F2.8 EX DC HSM Fisheye, 13.462 cm (5.3 ") , 12 x 7, 1:3.3
Sigma’s 10mm F2.8 EX DC Fisheye HSM lens is a diagonal fisheye which means the distorted scene is shown full frame within the camera’s field of view. The diagonal field of view produces striking images with exaggerated perspective of near subject & extreme barrel distortion of the surrounding areas. It allows photographers to shoot creative images by taking advantage of the acute perspectives that are invisible to the human eye. The diagonal fisheye is the most popular kind of fisheye and are often used by wedding photographers who want to give an “artistic” looks to images, by underwater photographers who want to take in the maximum field of view possible and by scenic photographers. The minimum focusing distance of 5.3 inches and magnification ratio of 1 to 3.3 allows the photographer to have fun with placement of subjects extremely near to the camera with distorted backgrounds. In the hands of an artist this lens can produce memorable, eye-catching images.
