21mm might cause some vignetting with the A series Cokin holder - possibly
the P series as well. I have in the past resorted to using adhesive tape to
attach the filter only to the front of the lens.

Shawn;
I would get the inexpensive Cokin filter holder. Then I would get an
expensive Tiffen GLASS graduated filter (the .6 is the 2-stop model).
In this case, you may need to get the Cokin 'P' series holder cause I
think the Tiffens only come in the 'big' size. I recommend against the
Cokins ONLY because they have a slight color cast IME. If you're not
THAT critical, the plastic Cokins in the A size and the A size holder
should be fine. Hope this helps.
