Hey Guys, I'm really getting into landscape photography. I wanna do stuff like this... Patrick Smith Photography - Landscape Photography and Seascape Photography - Home I just ordered a Tamron 17-50 f/2.8 and a new Manfrotto tripod, and now I need a good filter setup. This guy works with a Cokin Z-Pro Filter holder, and a set of Lee ND Soft Grads. I am looking to get the same thing, or something almost as good that's cheaper. I was thinking of these 2 items...
