The new Rokinon 35mm F/1.4 AS UMC Aspherical Wide Angle lens is an optically sophisticated lens designed for full-frame cameras. It can also be used on APS-C and Four Thirds cameras. The lens is beautifully constructed with two lenses made of quality glass with a high refraction factor. Weight and dimensions can therefore be as minimal as possible. The lens is also constructed with one aspherical lens that prevents horizontal chromatic aberration. Rokinon has also added a focusing scale to this new lens, which will help the user focus more accurately. With its high quality, dense, anti-reflexive layers, this new Rokinon lens produces stunningly high contrasts and perfectly reflects natural colors. Images come out crystal clear and sharp.
