Samyang 24mm F1.4 Wide Angle Lens - Sony FE Mount (7641) The Samyang 24mm f/1.4 ED AS IF UMC manual focus lens has been designed to work perfectly with most DSLR cameras equipped with full-frame and smaller image sensors. On full-frame cameras it constitutes a high-quality wide-angle lens perfect for street landscape and architectural photography. Photographers with DX sensors will have the perfect lens for photo-journalism and general landscape photography. When attached to Four-Thirds system cameras it creates a universal and bright optic corresponding to 50mm angle of view. The optical configuration of the lens is based on 13 elements arranged in 12 groups. Four of the elements use extra low-dispersion glass (ED) whilst two are Aspherical. Multi-layered anti-reflective coatings further add to perfect light transmission.
