I want to get a Lee 4x4 and wide angle 77mm ring for my Sigma 10-20mm.
I just bought a CF tripod and the 4x4 and adapter ring aren't cheap. I'm completely new to GND filters and polarizers.
Which 1 or 2 filters would be good for landscape photographer in general? I can add more filters later but would like something that will get me by for my roadtrip. Thanks
