Filter Systems

I have a Canon EOS 400D with the following lenses:
17-55mm (58mm diam)
80-200mm (52mm diam)

Ive been looking at Lee and Cokin P and Cokin Z series filter
systems.


Im wondering whether the Lee system is the only one which I can use
more than one filter on a wide angle lens (20mm)?


Im also wondering how either system allows you to correctly aling the
graduation to the object line (eg landscape/sky boundary)?


Thanks

I've pretty much given up on-the-camera filters, except for polarizers.
Here is a suggestion on graduated ND filter techniques in Photoshop. This
is one area where postpocessing gives you great control over the final
result.

Shoot a RAW image, using an exposure setting that averages the largest
possible area of the scene. Open the RAW image twice, once correctly
exposed for the sky and once for the landscape. Place the two images into
the layers of a new image file. Mask, erase, adjust transparency, etc., to
bring out the desired exposure results. You can fit your ND filter effect
with great precision!

For the lenses that you have Cokin P-system with standard holder (4 slots)
should be OK. I get vignetting with the standard holder only when use 10-22
lens from 16mm downwards. No vignetting occurs with Canon 17-85 or Sigma
18-125 at their widest focal length. Cokin Z-series will allow you to use 4
filters even with 10-22 lens.

THanks. I havent tried photoshop; Ive just moved from film to digital.
Have you previously used film and filters?

I have the Lee system and I'm pleased with it. I do get a bit of Vingetting
with my 12-24 Tokina when I have the hood pulled open.

It's a bit of a monster but the quality is great. you can spend a heck of
lot less money on the Cokin with the P series converter.
