Tiffen is showcasing the new Tiffen Variable ND Filter line at CES. Introduced in August 2011, Tiffen’s Variable ND offers both photographers and videographers convenience in price and performance by combining seven ND filters into one high-performance optical filter, the company says. They allow continuous control over the amount of light coming through the lens in an approximate range of two (ND 0.6) to eight (ND 2.4) stops. “What makes our filter stand out from the rest is the manufacturing,” said Jill Conrad, product manager for Tiffen. “The Tiffen Variable ND is made with high-quality optical glass using Tiffen’s established ColorCore technology. Many variable NDs on the market today use plastic or resin for one or sometimes both of the optical elements. Compared to glass, plastic and resin do not provide optimal image quality.” The filter is already available in 77mm size for a list price of $239.99. At CES, Tiffen is also showcasing the newly released 58mm and 72mm filter sizes.
