Cokin Filter mounts

[Apretext]

My Dad has lent me some Cokin filters, which seem to be about 66mmx66mm. Are these a standard size? My lenses have either 52mm, 67,77 and 82mm filter sizes, I'm guessing they will only work on the 52mm lens, or will they also just about fit on the 67?

They would only work on the 52mm lens, you would need the larger Cokin P range and of course the appropriate adapter to fit the other lenses.

What range are the 66mm square filters? Most adapters seem to be for the P range.

Edit: Ahh, would seem to be A series
