LEE Filters Polyester are a good, low cost alternative to resin filters. They are only 0.1mm thick and the optical quality is very high. The sets are supplied mounted ready to slot into your holder while individual polyesters are supplied with the frame for self-mounting. Polyesters are not available graduated.
Linhofstudio is the UK's largest stockist of Lee Filters and works very hard to ensure the full range of Lee products are always available from stock, including Polyester Sets, Polyester Technical filters, Polyester Black and White Filters, Polyester Neutral Density filters, and more.
