SIGMA 15mm F2.8 EX DG FISHEYE DIAGONAL Pentax

This extremely wide-angle professional EX lens, produced by the well-known Japanese company Sigma, has been designed as a full-form fisheye. This means that the resulting image, unlike with the circular type, covers the whole area of the picture. The fisheye lens's typical distortion can be used to photograph landscapes, unique snapshots and many other subjects. It is provided with a Super Multi Layer (SML) anti-reflective coating that minimizes the light reflected from the sensor. The lens also boasts excellent contour sharpness and contrast.

The lens is designed for digital SLR cameras with a standard 35mm film-sized sensor. It has a fixed focal length of 15mm and a f/2.8 aperture. A fixed sun shade is used to minimize light reflections.
