20mm F1.8 EX DG ASP RF

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. Such performance parameters provide great creative freedom to the photographer who wishes to exploit its capabilities for juxtaposing very near subject with the surrounding background. This extreme wide angle view also makes this lens ideal for crating “stitched” panoramic scenes for dramatic effect. The architectural photographer will find this lens attractive for shooting building interiors and the photojournalists will find its fast speed a life saver in low light conditions.

  Photo Notes: I live quite close to this area of the coast and get to see the sunrise most mornings, it always a great motivator.

  Photo Notes: I've always loved the shimmer of sunlight on the surface of the ocean, especially when there's a storm brewing. This is Shelly Beach on the north coast of NSW, Australia. A beautiful and still pristine marine environment, where migratory Southern Right whales sometimes come into feed their calf and shelter from the open ocean during big seas.
