The Cokin P filter holder has three slots. If you don't mind having only two slots, here's what you do: take a sharp utility knife and cut off the outer slot from the filter holder. Voila, no more vignetting. This 5 minute fix has served me well.
Good idea! ... however would like to know how wide can you go with 1 slot cut off (2 left) i.e. is 24mm ok?
I should have mentioned that I fixed my Cokin P filter holder for my Sigma 10-20 in this way. So I can't tell you exactly how it's going to pan out for a 24-105 on a 5D. However I can tell you there's quite a bit of gain in FOV.
