I need some feedback on this matter, i wish to use a polarizer filter in combination with a Graduated ND filter for landscape shots. Currently i am using cokin P system to hold ND Grad filters but i want to avoid using the cokin polarizer filter which according what i have read is a low quality-non multicoated filter.
My main concern is, if i use a screw in polarizer filter will i be able to screw the cokin adapter ring to it?
I suppose i always can handhold the Graduated ND filter in front the lens.

Many thanks

Yes, you can screw in a circular polariser and then screw in the cokin P filter adapter. You shouldn't get any vignette as the cokin adapter is pretty thin.

I've never had any problems screwing the Cokin adaptor ring onto my polarizer. Should go without any bother.

I never had a problem.

If you have a super wide angle lens (like 10-22) the P holder will vignette at the widest focal length (10).

Some of the slim polarizers don't have threads so holding the ND filter would be the only option though not really a problem.

Thank you all for your answers.

This is what is worrying me most:

From //www.hoyafilter.com/products/hoya/coatings.html :
Our ultra thin Circular Polarising filters have seven layers of Multicoating applied to their rear surface to eliminate internal reflections and ghosting. Advanced thin selective film is used to guarantee perfectly polarised light with neutral color balance. Their slim profile of just 5mm avoids any vignetting problems and makes them ideal for use with wide angle lenses. There is no front female thread, but they do accept our push-on lens caps. HOYA Super HMC filters will appeal to the most demanding of photographers who require the ultimate in performance.

Which one of those filters would you recommend me if any? http:Circular Polarizers

If you're using it on a super wide angle lens then I'd go with the slim S-HMC filter. I don't know what the difference is between this one and the HD version.

I am using a nikon 12-24f/4. Actually i find very confusing to find out the differences between them.

The first one in the list is not multi-coated so you can skip that one.

The S-HMC looks like the slim version of the HMC though the HMC doesn't say how many coatings. The S-HMC has 12.

I have found out that the S-HMC does not have female thread in the front due their slim profile, so it would not be possible to screw in the cokin adapter ring, see here so i think i can skip this one too.

This left only the following (i do not know if any of them lacks front female thread too):

Hoya 77mm Circular Polarizer (HMC) Multi-Coated Glass Filter
Hoya 77mm Circular Polarizing Pro 1 Digital Multi-Coated Glass Filter
Hoya 77mm Circular Polarizing HD (High Definition) Digital Glass Filter

Thanks for your help.

I have used the system you are looking at. You WILL get vingetting if you stack filters with the "P" system on a 12-2mm at the 12-13 range. I use a thin polarizer and hand hold the ND or stack and shoot at 14mm or more.

If you read the specs tab all those have front threads. Since they are not slim you may get some vignetting at 12mm. That's why the slim ones are usually recommended for the super wide angle lenses.
