Polarising Filter for Wide Angle Lens?

[James Blonde]

The thread size for the Sigma 10-20mm F4 is 77mm - I've got one, and I've got a circular polariser for it - its the Hoya thin / low profile filter (to avoid vignetting as much as possible), was about £90ish from Amazon, is perfectly good, HOWEVER it doesn't have a thread filter on the front of it, so can be a limitation if you want to add other filters. Which I do. Doh!

That Hama filter looks quite thick, so I'd want to try before I bought to make sure it didn't vignette at the widest settings. £32 would indicate a cheapie, but its down from £97, so perhaps not! AND it seems to have a thread on for adding filters! Might have to buy one myself for that price, although the reviews of it do give some pause for thought, especially on the vignetting.

The sigma 10-20mm f4 has a 77mm thread. I bought mine for £67 a Hoya PRO1 with low profile do stop vignetting. It works a treat and Hoya are one of the best names in the filter business.
