I've been looking into a Lee Foundation Kit holder (with a couple of 4x5 Hitech GND filters).
I'd also like to be able to use at least 1 GND with a CPL polarizer.
However, I see that the Lee polarizer is $300, PLUS, it appears that you need to buy some type of 105mm adapter ring for $119! Is this accurate? Do you really need to spend $419 just to add a CPL to the Lee Foundation Kit holder???
If so, is there any way to do this more economically?
