Cokin Filter Sizes

[DavidMartin]

Hi not wanting to appear dense but is a Cokin A filter smaller in size than a P.
I've recently got some A filters and holder which looks ok for my smaller lenses. But I've just bought a 67mm filter holder and the A size filter doesn't fit in the holder as they are to small. So will P filters be the right size. :shrug:

Thanks David

Cokin P filters are around 85mm, so the A series is a lot smaller.

...the A's are about 66mm.
