Any rect. filters that dont vignette at 24mm???

I have a cokin wide-angle system right now. I am pretty much cropping off the top and bottom of my photos for anything wider than 30mm even with this system.

Are there any systems don't vignette? I wanted a ND filter for landscapes at wide angles primarily. This seems to defeat the purpose slightly.

You may want to go with the Lee system or the Cokin Z; they're 100 mm across rather than the 75 mm of the Cokin P system.

Oh, nevermind! I discovered my problem. Because the cokin filter holder is basically "free spin," I was pushing the tab ever so slightly so it would lock onto the adapter ring. This was actually creating a slight lip over the glass which was blocking light. So the wide does actually work as long as im at 28mm and up. Now I just need to make sure the filter is always straight when shooting!
