Popis
The Samyang T-S 24mm f/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 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.
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 and two Extra Dispersion (ED) lenses. These elements enable the lens to perfectly reproduce detailed elements and provide superior optical performance even when using the tilt and 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 and natural colours. With sophisticated optics and 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.
The tilt-shift function in the Samyang T-S 24mm f/3.5 ED AS UMC allows for smooth and fine adjustment of the focal plane by an angle of +/-8.5 and enables parallel shift of the optical axis by +/-12 mm. To make Tilt-Shift function even more seamless, both the lens mount and the 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 (with 30 degree adjustment). Filter size is 82mm.
