Hi to all...

I want to purchase some filters. I already brought a 72mm screw Hoya filter, but i was interested in the Cokin system. However i do not understand what type pf product i need for the XL2. I need an adapter ring, a filter holder and a sunshade; i don't know if i need the P series or the Z-pro series. Theorically the P series will be enough: it says "for larger diameter lenses, up to 82mm; recommended for focal lengths from 28 mm onward (35mm format); while the Z-pro series is for lenses up to 96mm and focal length from 20mm onward.
I asked at some shops here in my city and they only have the P-series. So before buy something i need to know if the P series will work without causing vignetting. Any experience?

Uh... noone?

Two questions:

1) Why do you want to purchase some filters?

2) What type of shooting (projects) will you be doing?

Well, i was mainly interested in gradient filters, to use when the foreground is well exposed but the sky is blown out; and that sort of things.

I do shorts, music videos...
