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 precisely control the lens when shooting under various exposure conditions, including relatively dark or overly bright situations. This lens features 11 elements in 7 groups, particularly including an extra low dispersion lens (ED) 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 to film subjects that are very close. Moreover, the floating design allows for maximum light and maximizes 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 Line Up for full-frame image sensors. The lenses produce the same color rendition and have a common position for the aperture and focus gears to maximize comfort while filming.
