The Samyang 35mm f/1.4 AS UMC AE is a fast wide-angle manual focus lens compatible with full-frame cameras as well as APS-C or smaller sensors. This Auto Exposure (AE) chip version of the Samyang 35mm incorporates an electronic circuit that allows full control of exposure settings accessible from the camera body. On Nikon bodies, this feature includes i-TTL flash communication and EXIF data with all Nikon digital SLRs (both full-frame FX bodies and cropped sensor DX bodies). Samyang now offers this capability to Canon EOS cameras, with the AE version equipped with a chip for full AE functionality and focus confirmation with Canon SLR bodies. Offering excellent resolution and sharpness across the entire image, equalling or surpassing lenses three times more expensive, the Samyang 35mm lens is truly a professional-quality lens at an affordable price. On a full-frame Nikon FX and Canon EOS SLR, the 35mm focal length offers universal applications with the fast f1.4 aperture, particularly for journalism, portraiture and low-light photography. With its high resolution, it is also popular for landscape photography. When mounted on a Nikon camera with a DX sensor, or on Canon APS-C size sensors, it becomes a versatile standard lens of approximately 50mm to 55mm. The wide apertures of the Samyang 35mm deliver beautiful bokeh (the character of out-of-focus areas), perfect for portrait-type applications, or photography where ultra-soft and blurred backgrounds or foregrounds are desired. This technique helps to separate the subject from the background, giving very pleasing and professional results, particularly in portraiture or photojournalism. Aided by its 8-blade aperture design, the smoothness of the bokeh delivered by the Samyang 35mm is excellent. Although bokeh character is a personal preference, various independent tests and users rank the Samyang 35mm lens as one of the finest lenses, regardless of cost or manufacturer, for its bokeh character. The optical design of the Samyang 35mm f1.4 UMC lens comprises twelve elements arranged in ten groups and includes two high refractive index elements, which help to reduce its weight and dimensions to a moderate level for a lens capable of covering full frame. The inclusion of an aspherical optical element minimises and helps reduce lateral chromatic aberration, while UMC multi-layer coatings deliver high contrast and faithful colour reproduction. The design incorporates floating elements to preserve high image quality at the minimum focusing distance. It features a wide, comfortable manual focus ring and is perfectly suited to most photographic applications. Precise focusing for critical situations can be achieved through the use of Live View focusing, available on most new Nikon camera models. There is a growing number of users employing Canon and Nikon SLRs for High Definition (HD) video shooting, and manual lenses allow users precise control of focus during shooting. The Samyang 35mm F1.4 AS UMC has been designed with attention to the finest details, both in terms of optics and construction, which places the lens among the finest photographic products in its category. Supplied with front and rear lens caps, a petal-shaped lens hood (which is reversible for transport) and a soft lens pouch. Filter diameter 77mm specifications
