Cokin’s new Pure Harmonie filters are billed as the smallest and lightest photo filters 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), Cokin Pure Harmonie filters are super-lightweight and cause no vignetting. The new line-up will be available in stores by the end of the year, in a variety of sizes.
