Samyang's creative innovation impresses the world ever morenn- Extra low dispersion (ED)n- Glass aspherical lenses (AS)n- 8 pieces of circular aperturen- Ultra multi coating(UMC)n- F 1.4 wide aperturesn- Internal focusing(IF)nnSamyang 24mm F1.4 ED AS UMC is a high quality, fast aperture, prime wide angle lens for full frame or APS-C sized sensors. It is ideal for full-frame cameras, constituting a high-quality wide-angle lens perfect for shooting street, landscape and architecture even in low light conditions. The sharpness if excellent, even at the edges of the frame at wide apertures, and the fast F1.4 aperture is able to give a narrow depth of field when needed.nnSamyang 24 mm F1.4 ED AS UMC is a manual focus lens. The manual focus ring is wide, easily accessible and perfectly adaptable to most photographic applications. Accurate focus at very close distance or focus critical situations can be achieved through use of focusing in live view mode, available to most newer camera models. Furthermore the 24mm provides lovely bokeh (the character of out-of-focus areas), due to its design and fast aperture. Optical construction of the Samyang 24mm lens features 13 elements arranged in 12 groups, 4 of them low-dispersion glass (ED), and 2 of them aspherical. The 24mm is Ultra Multi Coated (UMC) for the best possivble light transmission, and reduction of ghosting and flare. Supplied with detachable petal shaped lens hood, lens caps and soft lens bag. Filter size is 77mm.nnAvailable for: Canon EOS, Canon M, Nikon AE, Pentax K, Sony A, Sony E, FT, MFT, Samsung NX, and Fuji X.nnLow dispersionnnLow dispersion lenses decrease dispersion of unnessarry light so that make aberration little effectively.nnGlass asperical lensesnnThe adaption glass asperical lenses reproduce aberration to get high quality image in center and edge of frame and excellent contrast.nn8 pieces of circular aperturennThis lens is designed to have 8 pieces of circluar aperture so render beautiful buttery bokeh.nnUltra multi coating(UMC)nnWe apply the UMC(ultra multi coating) of our own technology to reduce flare and ghost as much as possible and get clear and fresh color image.nnF 1.4 wide aperturesnnSmooth focal control gives you precise adjustment and also F 1.4 wide aperture gives you touching photography.nnInternal focusing(IF)nnThe internal focusing controls focusing inside of barrels so that is so free from contamination of dust.
