Advice on P size filter holder and polariser

alet · 12 Oct 2012

Im in the market for a p size filter holder for 85mm square filters, and was hoping for some advice please. I have just bought a set of hitech nd filters on here that i will be using with it.

Holders are available at such a wide variety of prices. The cheap ebay ones seem attractive because they come with such a wide selection of adapter rings. Any experience of these? I would be grateful for any advice.

I will eventually invest in a circular polariser for this holder. Does anybody have experience with the Kood / SRB Griturn polarisers that claim to be compatible with these holders? Any compatibility issues? Or will they just work on any ebay filter holder?

When I had 85mm filters I used the Kood CPL that drops in the back slot (nearest to the lens). I used compatible holders and didn't have a problem. It was fine.

Does it make a difference which slot you put it in ?

It will only fit in the rearmost slot in a P series holder.

Oh o assumed all the slit would have to be the same size or am I missing something

There is a very slim slot at the back of a P series holder for a CPL.

Yes, nearest the lens. It is about half the thickness of the filter slots.
