Re: Have you considered the Lee filter system?

I'll look into cokin holders and lee filters at the store.  but someone else said that when using 10 stop ND slide in filters, light goes inbetween the filter and the lens.  is this an issue?

As pointed out, I think the big stopper has some kind of sealing to prevents leak - but I'm not sure if that is only with the lee holder, or if it would work with the cokin holder as well.

With the Cokin IR filter in a Cokin holder, even in the slot closest to the camera, there is a small gap. Now with IR filters or strong ND filters, you have to use long exposure times, so any light leak can show up. I have seen bad examples of the Cokin IR filter with light leaks.
