SIGMA 15mm F2.8 EX DG FISHEYE for Canon

This extremely wide angle professional EX class lens from the well-known Japanese company Sigma is designed as a full-frame fisheye lens. This means that an image here, unlike the circular type, covers the entire image. Its typical distortion is used for photographing landscapes, unique snapshots, and many other scenes. It is regulated by an anti-reflective Super Multi Layer (SML), which minimises light reflections from the sensor. It also boasts excellent edge sharpness and contrast.
This lens is designed for digital SLR cameras with classic 35mm box sensors. The lens has a fixed focal length of 15mm and aperture f/2.8. The polycarbonate lens hood helps to minimise light reflections.
