btw, another concern i have is isn't you guys feel troublesome to use a CPL as you need to take out the CPL when shooting other thing if feel it is too dim or indoor. And when you are shooting at sky, landscape, water, or glass then you put it on again? :think:
CPL is only used when necessary, it's not an "always on" filter. Never had any hassle with CPL. Initially I had some hassle with UV+CPL like filter got stuck, removing UV and putting on CPL). Now UV stays at home, not necessary for the picture.
