Add professionalism to your creativity with Samyang extra-wide-angle lensnn- Samyang Optics’ Nano Coating Systemn- Wide angle of 109.5° and low distortionn- A bright aperture of F=2.8n- Glass aspherical(AS) and low dispersion(ED) lensesn- 6 aperture blades creating almost circle shapennIt is a extra-wide-angle manual focus lens designed for APS-C crop sensor camerasnnWith low distortion and wide angle (109.5°), photographers who want wide-angle photos such as landscape and architectural images can create satisfactory images. F2.8 is very bright even under relatively dark environment, clear and vivid images can be captured.nnOptical construction of Samyang 10mm F2.8 ED AS NCS CS features 14 lenses in 10 groups – among lenses, there are 2 glass aspherical lenses(AS) and 1 low-dispersion glass(ED). It realized the minimum focal length of 0.24m. Also, for the first time in Samyang Optics history, the independent NCS(Nano Coating System) was used. It creates even lower reflection rate than the original UMC (Ultra Multi Coating) and higher contrast. Also, the light penetration rate is very high to minimize flare and ghost.nnThere are 6 aperture blades designed to be almost as a full circle when aperture is closed which expresses starlike ray clearly and beautifully in deep depth of field image. The frame of Samyang 10mm F2.8 ED AS NCS CS is compact and solid since it is made of high-strength aluminum alloy. Trustworthy images can be captured even under inferior environment. Also, petal-shaped lens hood to shelter lens from unnecessary light is provided.nnAvailable for 10 camera mounts: Canon, Canon-M, Nikon AE, Pentax, Sony ∝, Sony-E, Four-Thirds, MFT, Samsung NX, and Fujifilm-X.nnSamyang Optics’ Nano Coating SystemnnFor the first time in Samyang Optics history, NCS(Nano Coating System) is used to lower reflection rate more effectively to provide higher contrast.nnExtra-wide-angle lens of professional levelnnRealized wide-angle of 109.5° and low distortion to create crisp images for landscape and architectural shooting.nnBright aperture (F=2.8)nnF 2.8 enables taking vivid and sharp photo even in dark environment.nnGlass aspherical lens(AS)nnIt provides the high quality and contrast image even when aperture is fully opened by revising color aberration.nnLow distortion lens(ED)nnIt lowers unnecessary light dispersion to effectively dropped color aberration.nnAperture with almost full circlenn6 aperture blades creating almost a full circle when closed express ray beautifully as starlight.
