The Samyang 135mm T2.2 VDSLR ED UMC enables finer video work with T-number markings. The focus gear is mounted for follow focus systems. With the decoupled aperture gears, you can change the aperture quietly and smoothly. Additionally, the distance scale and T-numbers are marked on both sides of the lens. The Samyang 135mm T2.2 VDSLR ED UMC is a manual focus lens with a low T-number. You can control the lens precisely when shooting under various exposure conditions, including relatively dark or overly bright situations. This lens features 11 elements in 7 groups, including an extra low dispersion (ED) lens to ensure high resolution across the entire image. Samyang Optics' Ultra Multi Coating (UMC) is used to optimize light transmission and minimize stray light and ghosting. With such an optical design, it has a minimum focusing distance of 0.8 m, allowing you to film subjects up close. Moreover, the floating design maximizes light and enhances resolution by minimizing spherical aberration and distortion. The Samyang 135mm T2.2 VDSLR ED UMC is part of the Samyang Optics VDSLR II Cine Lens lineup for full-frame image sensors. The lenses produce consistent color rendition and share a common position for the aperture and focus gears to maximize shooting convenience.
