Samyang manufactures the highest quality filter glass using German SCHOTT material (B270). The digital multicoated filter (UMC) increases light transmission and reduces flare. It absorbs ultraviolet rays and minimizes reflection at filter surface in order to deliver clearer and sharper images minimizing haze and indistinctness.\n\nUV filters are considered to be a standard accessory for every SLP lens, including the lens that may have come with your camera. The size is designed to fit the threads on the front of your lens. UV filters not only help to protect your lens from dust, moisture and scratches, it also allows you to improve UV effect and minimize reflections at filter surfaces, which reduces flare and ghost on the photos.
