Product Description
100x125mm Size filter. Fits Hitech 100mm, LEE and Cokin Z-Pro systems. Single filter is usable on multiple lenses
100mm is a popular size for smaller consumer DSLR lenses and mirrorless cameras.
Made from the highest quality CR-39 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.
Neutral density (or ND) filters produce a grey neutral tone and are used in photography to reduce light, enabling more control over exposure and depth of field without affecting colour contrast. NDs are also available in graduated filters, both in hard and soft edge. These filters are clear in the bottom half of the filter with a gradual transition to the ND effect in the top half. They are primarily used for light reduction in skylines of landscape shots.
Graduated NDs are available in Soft Edge or Hard Edge varieties. Soft edge grads have a smooth transition from clear to ND. Hard-edge grads have a more defined hard lined transition and are usually used for longer focal lengths.
ND Grads are made in different densities according to the level of light reduction from 1/3 to as much as 4 stops of light. This 100mm Hard Edge filter is usable with Hitech 100mm holder systems or any 100mm (4") holder. The 0.3 filter reduces light by 1 stop. The filter is 100mm wide but 125mm (5") long so that it can be moved up and down in the holder to line up the graduation line easily with the horizon. A 100mm (4" x 150mm (6") version is also available for added flexibility. The filter is also available in 85mm, 150mm and 165mm sizes.
Hitech filters are made from the highest quality 1.5mm optical resin.
