The Samyang T-S 24mm f/3.5 ED AS UMC tilt-shift lens is a full-frame wide-angle lens with perspective control and tilt-shift functions. Its unique optical and mechanical construction makes it an ideal tool for architectural and landscape photography. The product is extremely useful for correcting converging lines and controlling perspective. The optical tilt mechanisms allow precise control of depth of field as well as perspective control, which can also be used for creative photography and perspective exaggeration, allowing photographers to shape the image according to their individual needs. Suitable for both digital and film formats. The optical design of the Samyang T-S 24mm f/3.5 ED AS UMC comprises sixteen elements arranged in eleven groups, including two aspherical elements and two extra-low dispersion (ED) elements. These elements allow the lens to reproduce details perfectly and deliver superior optical performance, even when using the tilt-shift (T-S) functionality. In addition, every optical component has been coated with UMC multi-layer anti-reflection coatings, which provide excellent light transmission, high contrast and natural colours. With its 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 of the Samyang T-S 24mm f/3.5 ED AS UMC allows fine and smooth adjustment of the focal plane at an angle of +/-8.5 degrees and enables a parallel displacement of the optical axis of +/-12mm. To make the tilt and shift functions even smoother, the lens mount and the T/S section can be rotated on the optical axis. The tilt-shift section can be rotated 90 degrees to the left (with a click stop every 30 degrees), while the lens mount can be rotated 90 degrees in both directions (with a click stop every 30 degrees). The filter size is 82mm. technical specifications
