I need a filter kit; I already have a CPL and a screw-on 9-stop Hoya filter, but I'm going to need some more serious stuff for a landscape workshop. The guy doing the workshop recommends a starter kif of Lee filters but they seem to be a) expensive, and b) out of stock everywhere I look (trying to keep to UK or EU shops to avoid insane shipping fees). Can anyone recommend a comparable quality system that doesn't have a months-long waiting list?
That's like two thirds of the cost of the entire workshop...
. Still pretty steep...
