Filter systems

I'm looking for some advice on filter systems so I can use just one filter for all my lenses. I currently have a lens with a 67mm filter thread and two lenses with 77mm filter thread. My filters are limited to just uv protectors and polarizers. I'm looking for a filter holder system so I can get ND filters, Grad ND filters and a good circular polarizer and only need one of each for all my lenses and to avoid vignetting on my wide lens while stacking multiple filters. Does anyone have any suggestions for a good system at a reasonable price? Thanks guys.

are you referring possibly to a step up or step down ring? I have a couple 62mm filters and I use a step up ring when I move to my larger lens. The only other types i know of are the cokin filters and you can get rings to fit the various lens openings.

You're looking for the Cokin P system. Fits lenses up to 77mm (or is it 82mm), tons of filters available.

I'll second the Cokin P system. Works very well and is reasonably priced.
