Samyang's optical technology produces soft blurring imagesnn- Glass aspherical lensesn- Extra low dispersion(ED)n- Tilt shiftn- Ultra multi coating(UMC)nnThe Samyang T-S 24mm F3.5 ED AS UMC is a wide-angle, full-frame lens fitted with the perspective control and tilt-shift functions.nnIts unique optical and mechanical construction makes it an ideal tool for architecture and landscape photography. The product is extremely useful to correct convergence of lines and perspective control. The optical tilt mechanisms enable precise control of depth of focus along with perspective control which can also be used for creative photography and perspective exaggeration, enabling photographers to shape the image according to their individual needs. Suitable for both digital and analogue film formats.nnOptical design of the Samyang T-S 24mm F3.5 ED AS UMC comprises sixteen elements arranged in eleven groups, including two aspherical lenses and two Extra Dispersion (ED) lenses. These elements enable the lens to perfectly reproduce details and provide superior optical performance even when using the tilt and shift (T-S) functions.nnFurthermore, each optical component has been covered with multi-layered, anti-reflective UMC coatings, which provide superb light transmission, high contrast and natural colours. With sophisticated optics and developed T-S function, the Samyang T-S 24mm F3.5 ED AS UMC is currently one of the most advanced lenses produced by Samyang Optics.nnThe Mount Rotation Lever enables as a combined unit the Tilt and Shift Sections to be rotated RIGHT up to 90 degrees (with 30 degree adjustment). The Tilt Rotation Lever enables the Tilt section to independently rotate LEFT by 90 degrees (with 30 degree adjustment). Filter size is 82mm.nnAvailable in Canon EF and EF-M, Fujifilm X, Olympus / Panasonic Four Thirds and Micro Four Thirds, Pentax K, Samsung NX, or Sony A and E mount versions.
