Samyang has announced that it will be showing a protoype of a 10mm 1:2.8 ED AS UMC CS lens at Photokina. With its 15mm-equivalent, 110 degree angle of view, it will be the widest-angle rectilinear prime lens for APS-C/DX format SLRs. As usual for Samyang, focusing will be manual only. The lens is expected to go on sale towards the end of 2012.
Samyang 10mm 1:2.8 ED AS UMC CS is a prototype of the ultra wide-angle prime lens designed for use with cameras fitted with APS-C/DX sensors. Its extremely short focus length and rectilinear imaging system ensure extra wide angle of view amounting to 110 degrees (~107 degree for Canon version). As a result the lens is a comprehensive tool for architecture and landscape shooting. New Samyang 10mm 1:2.8 ED AS UMC CS is similar to the 35mm system lens with 15mm or 16mm focal length in the case of Canon APS-C cameras.
All details concerning the optical construction of the lens and available mounts will be published at a later date. The lens will be introduced for sale either at the end of 2012 or in the first days of 2013.
