Sigma 15mm f/2.8 Aspherical EX Fisheye Autofocus Lens for Pentax K-Mount {Rear Gel}

The Sigma 15mm F2.8 EX DG Diagonal Fisheye holds a distinctive position in the Sigma lens line up. With the diagonal fisheye the distorted scene is shown full frame within the camera’s field of view. The diagonal field of view produces striking images with greater perspective of close subject and maximum barrel distortion of the surrounding areas. The lens enables photographers to shoot creative images by taking advantage of the acute perspectives that are invisible to the human eye. 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 this is the most popular fisheye lens used.
