Which Filters for Sigma 10-20mm

[Happysnapper79]

Hello all, I have just purchased a Sigma 10-20 f 3.5 lens and would like to get some filters for it. Having used Cokin in the past its a brand I am comfortable with, does anybody know which would be best for use at 10mm without vignetting out of the X-Pro and the Z-Pro filter series.

Many thanks in advance.

You need the Z-Pro
