Hampstead, MD—Cokin launched its Pure Harmonie line of round photo filters, which are distributed by OmegaBrandess. The filters are said to be the “thinnest and the lightest in the world,” with a thickness of 3.3mm for the multi-coated anti-UV (UV MC), 4.5mm for the circular polarizer (C PL) and 9.5mm for the variable density neutral gray (ND X) filters.
Nearly invisible when mounted on a lens and light in weight, Cokin says they have been engineered “with no compromise: very robust, compatible with all lens caps and multi-coated with EverClear 5 Coating technology to withstand almost any conditions. Super lightweight for maximum AF performance and ultra-shallow profile to prevent vignetting, they are just perfect. They are Pure.”
Anti-UV filters are used to prevent ultraviolet light from getting through the lens, by reducing haziness or fogginess caused by that type of light. Anti-UV filters also offer physical protection from dust or scratches to the lens. Pure Harmonie UV MC filters are made of resistant glass with a high level of light transmission. Thanks to their extreme thinness, the filters also prevent lens flare.
Circular polarizer filters are used to reduce reflections from nonmetallic surfaces (windows, water) and increase density within the sky and/or foliage by absorbing reflected light. They’re also engineered to emphasize details such as clouds and makes pictures crisper, with deeper color tones.
Neutral density filters reduce the quantity of light that reaches the sensor of the camera and allow users to decrease the shutter speed in order to achieve motion blur and/or to reduce the depth of field in very bright conditions. As they are “neutral,” ND filters do not affect color rendition. With Pure Harmonie variable density neutral gray filters, users can select the intensity from ND2 (1 f-stop) to ND400 (8+ f-stops) by rotating the front ring. omegabrandess.com
