Product Details

This Sigma 20mm F1.8 EX DG Aspherical RF is a unique Sigma offering with an aperture of F1.8 making it the fastest super wide angle lens available from any camera or lens manufacturer. For the scenic or landscape photographer it’s important to have a wide angle lens with excellent optical performance and Sigma’s aspherical lens technology provides high quality images for the serious shooter. Sigma’s 20mm lens has a field of view of 94.5º and yet provides for a close focusing lens-to-subject distance of only 2.6 inches.
