So I'm looking at getting some filters once I get some money and would like some advice. I am just starting out in photography and have a Nikon D90 with the 18-105mm kit lens. I currently have no filters at all. I am into landscape photography and enjoy sunsets and water photography. I have come up with a list of filter types that would be most useful for this lens. UV Filter (protection?) Circular Polarizer Neutral Density (1?, 2, 3, and 4 stop filters) - What are the most commonly used values for these? Graduated Neutral Density Here is a link to a wishlist I made on B&H. They are all Tiffen filters except for the Grad ND setup which is from Cokin. Being extremely budget conscious and a hobbyist photographer, are these of sufficient quality to suit my needs? Any input is appreciated. Thanks!
