The Samyang 35mm T1.5 AS UMC VDSLR lens is a fast, wide angle, manual focus prime lens for full frame cameras, or a fast standard prime when used on APS-C/DX sensors, available mounts for Canon, and Nikon fit
This VDSLR (Video DSLR) version has been developed primarily for professional cine / movie making purposes. The VDSLR version feature follow focus gearing and decoupled aperture, which allow the user to smoothly and quietly change focus and aperture / depth of field whist filming, and link to professional follow focus cam systems.
The Samyang is rated in T-Stops rather than F-stops which is usual for movie camera lenses. F-stop number expresses the speed of the lens on the assumption that lens transmits 100% of the incident light. The T-number expresses the actual light transmission, which is more accurate, and is the standard in professional cine lenses.
The Samyang 35mm T1.5 AS UMC VDSLR lens version is optically the same as the standard Samyang 35mm f1.4 AS UMC version.
Producing superior resolution and sharpness throughout the image equal or exceeding lenses 3 times as expensive, the Samyang 35mm lens is truly a professional class lens at a affordable price.
Suitable for full frame and cropped sensors the 35mm focal length has universal applications, the lens is bright / fast wide-angle lens perfect for landscape, journalism and general shooting applications, including low light photography. When mounted on a camera with APS-C sensor, will become a popular, multitasking 50mm prime lens, perfect for general photography including low light photography.
AT wide apertures the Samyang 35mm video lens provide beautiful bokeh, (the character of out-of-focus areas) which is perfect for portrait type applications, or photography where ultra smooth out of focus backgrounds or foregrounds is preferred. This technique helps to separate the subject from the background giving very pleasing and professional results in both film and still photography. Aided by its 8 aperture bladed design, the smoothness of the bokeh provided by the Samyang 35mm is excellent. Although bokeh character is a personal preference various independent tests and users rate the Samyang 35mm lens as one of the best lenses regardless of cost or manufacturer when it comes to its bokeh character.
The optical design of the Samyang 35 mm T1.5 lens is twelve elements arranged in ten groups and includes two elements with high refractive index, which helps reduces its weight and dimensions to a moderate level for a full frame capable lens. The inclusion of an aspherical optical element minimizes helps reduce lateral chromatic aberration, UMC multi-layer coatings provides high contrast and faithful colour reproduction. The design incorporates floating lens elements allowing to preserve high image quality with minimum focusing distance.
The focus ring features toothed rings compatible with professional geared follow focus systems available in the film industry and likewise a toothed, decoupled (de-clicked) aperture ring. Such modifications allow for smooth and precise control over focus and aperture during video recording / filming. This allows for ultimate manual control of focus and exposure when filming from one scene to another with different light source intensities, such as changing exposure values (EVs) from inside to outside, or even in-camera fade ins etc.
The Samyang VDSLR versions can be used in still photography as well as for video purposes. There are increasing numbers of users using DSLRs for filming and High Definition (HD) video and manual lenses allows the user to change focus (focus pulling) and aperture during filming.
Samyang 35 mm F1.4 AS UMC has been designed with great emphasis on the smallest details to both optics and workmanship, which place the lens among the best photographic products in its class.
