Most good camera shops should sell them - makes such as Hoya, Lee, Hi Tech, Cokin, etc.

I use Cokin filters because for graduated ones their system is easy - web site in link they have outlets in most countries if you click on 'contact us' it has phone numbers and addresses for them.

All makers use same notations for them so look for:

Filter ND2 = 1 F stop less
Filter ND4 = 2 F stop less
Filter ND8 = 3 F stop less

Should have said if you do use Cokin get the p size holder.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
