I am asking in this share as I wish to have the thoughts of landscape photographers. I now have the Lee filter holder and CPL ring. I have an intermediate solution of using an old cheapo glass from a 105mm CPL, which is held in place using the adaptor and the front plates of the holder.
I am wondering which CPL you guys would recommend, I realise there are not so many out there (Lee, Sigma... ?) and your thoughts on how good they are (the ones you have used).
I won't be buying this month, the 500GB harddisk had to come first before my PC sank under the weight of 5D raw files
but I know I need one.
