I have a Nikon

i have been looking at the Cokin z-pro kit
but can't find to much info on this produced!
is ther a better product out there that would be better for the lens i have?

If you can afford it (check eBay), get a Nikon filter. I've always felt that what you put in front of the lens should be as good as the lens itself.

Ckm1956 is right

Which and filter you buy has more to do with how much light you need to remove from the scene.

Each of the lenses you listed may need a different size filter. 52 mm, 62 mm, 67 mm, etc.
