The Samyang T-S 24mm f/3.5 ED AS UMC is a wide-angle, full-frame lens fitted with the perspective control & tilt-shift functions. Its unique optical & mechanical construction makes it an ideal tool for architecture & landscape photography & is extremely useful to correct convergence of lines & 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 & perspective exaggeration. The optical design of the Samyang T-S 24mm f/3.5 ED AS UMC comprises sixteen lenses arranged in eleven groups, including two aspherical lenses & two Extra Dispersion (ED) lenses. These elements enable the lens to perfectly reproduce detailed elements & provide superior optical performance even when using the tilt & shift (T-S) functionality. Furthermore, each optical component has been covered with multi-layered, anti-reflective UMC coatings, which provide superb light transmission, high contrast & natural colours. With sophisticated optics & developed T-S function, the Samyang T-S 24mm f/3.5 ED AS UMC is currently the most advanced lens produced by Samyang Optics.
