Hitech's 165x165mm Clear Filter is used to create your own effects. This may be done in any number of ways but some examples are drilling, smearing with oil or other substances, or painting. The 165mm size is useable with Hitech 165mm holder systems designed for wide angle lenses.
165mm is a high-end system for photographers using large-barrel, wide-angle lenses such as the Nikon 14-24
Fits the Formatt-Hitech 165mm Formatt-Hitech or Lucroit holder system, so a single filter is usable on multiple lenses
Made from the highest quality optical resin available, with an index of refraction nearly identical to the finest optical glass
High scratch resistance, low material fatigue, and chamfered corners to resist breakage so the filter will provide years of service
Made in the UK using the world's most advanced, computer-controlled filter manufacturing technologies
