Samyang T-S 24mm 1:3.5 ED AS UMC is a wide-angle, full-frame lens fitted with the perspective control and tilt-shift functions. Its unique optical and mechanical construction makes it an ideal tool for architecture and landscape photography. The product will be also extremely useful when convergence of the lines in the frame is required. Owing to the mechanism of optical axis tilt, focus depth operation brings utterly new quality and possibilities, enabling photographers to shape the image according to their individual needs, both on digital and analog carriers.nnOptical design of Samyang T-S 24mm 1:3.5 ED AS UMC comprises of sixteen lenses arranged in eleven groups, including two aspherical lens and two lens made of ED glass with low dispersion factor. Thanks to this solution, the lens perfectly reproduces detailed elements and gives splendid image plasticity, also with the T-S function on. Each optical component of the product was covered with multi-layered, anti-reflective UMC coatings, which provide great light transmission factor, high contrasts and render only natural colors of the photographed scene.nnWith sophisticated optics and developed T-S function, Samyang T-S 24mm 1:3.5 ED AS UMC is currently the most advanced lens produced by Samyang Optics and may compete with similar lenses of other brands.nnTilt-Shift function in Samyang T-S 24mm 1:3.5 ED AS UMC allows for smooth and individual adjustment of the focus plane angle by +/-8.5 and enables parallel shift of the optical axis by +/-12 millimeters. To make Tilit-Shift function even more seamless, both the lens mount as well as Tilt-Shift section may be rotated on the optical axis. The Tilt-Shift section may be rotated left by 90 degrees (with 30 degree adjustment), while mount of the lens may be rotated both in left and right direction by 90 degrees, also with 30 degree adjustment.
