We hardly need to remind you of the drawbacks of gelatin filters. They're prone to buckling and dimpling. They're more susceptible to nicks and scratches than any other kind of filter. And they're virtual magnets for dust and grease, yet can't be cleaned! All that means you end up throwing gelatins away when you think their condition might injure the image - or you shoot with a dirty filter and hope for the best. Optiflex filters put an end to that gamble. Available in 3x3- and 4x4-inch sizes, in a full range of CC, CTC, ND, and black-and-white types, Optiflex filters are made from the same dyed-through optical resin as rigid Hitech filters- so they deliver the same superior image quality. Yet Optiflex filters are just 0.3mm thick. That means they're thin enough for use in gelatin filter holders, but still rigid enough to prevent warping and buckling. Their resin base also makes them much more scratch-resistant than gels. And you can clean them just like a glass filter.
