Polarizer + ND Grad

I want to combine ND grad filters and a polarizer on my N65 with 2

different lenses (50/1.8, 28-105/3.5-5.6).

The filter sizes are 52mm and 62mm. I'd like to be able to use the

same filters with both, so I was looking at the Cokin P system for

the ND Grads and planned to get the 62mm Nikon Circular Polarizer

(and use a step-up ring for the 50/1.8). But it appears that the

front threads of the CP are larger than 62mm. I can't find that info

online, so I don't know if I can get an adapter to work with the

Cokin system.

What is the best approach here? Is it critical to polarize before an

ND grad? If I get a Cokin P type circular polarizer, which brand

should I get (I hear the Cokins aren't great)? I want to plan for

everything to work as wide as 28mm without vignetting.

Hi Jim,

You've heard right about the quality of Cokin grad filters (they

aren't neutral) And while it is extremely rare that I've ever needed

to combine a graduated Neutral Density and a polarizer it does

happen. See the attached example. It was shot with a Heliopan

polarizer and a Lee 0.6 ND grad filter mounted on a Nikon

17-35mmf/2.8D AF-S Nikkor (camera & film; Nikon F5 & Fuji

RDPIII)<P>

I recommend you get the Lee Filter foundation kit, a w/a 62mm

attachment ring and a 62 to 52mm step down ring.
