I am looking at a Graduated ND to go with my Canon 24-70 and a probable purchase of the 17-40. Specifically I am headed out west (Zion, North Rim GC, etc) in June. These have a 77mm diameter. So I got a Cokin P series based upon the recommendation of the salesman.

But after reading the catalog in the package, it seems I would need a Z-PRO to go below 28mm and the X-PRO to get below 20mm.

Any feedback or experience using these?

Also any opinions on which of their GNDs to get? I am specifically buying it to deal with the fact I will be in the canyon during the day and I want to adjust for the sky. I read another thread that talked about the Singh Ray, which have a 'soft' gradation and a 'hard' gradation, and another that talked about a minimum of a +3 stop filter.

I've heard that you should take both a +2 and +3 for most assignments, but I havent actually used any myself.

It's true, the P holder might vignette a bit at really wide angles. I was all set to buy one until I learned this. I am going with a Lee instead, which Lee assured me would work fine with my 10-22 if I had a wide-angle 77mm adapter ring and if I only had 1-2 filter slots installed instead of the supplied 3 slots.

The nice thing about the P system is that Singh-Ray and Lee (and others) make G-NDs for this system andof course the fairly compact size. The Singh-Ray looks great (the Galen Rowell model).

I have a P series on my Nikkor 18-70 and haven't noticed any problems. I even have a skylight fliter on which pushes the cokin setup a little further from the lens. This goes on my D70 which has a 35mm factor of 1.5.

I have quite a few filters if your interested in buying I might be interested in selling :rofl

Cokin P set-up on the 17-40 will start to intefere around 24mm, if you get the Cokin ultrawide holder you gain around 4mm and can get it down to 20mm. I would suggest slimline screw in filters or even as previously suggested the Lee system
