[Dunx90]

Been looking for a 10stop filter for my sigma 10-20mm been looking at the B+W but not sure which one to get seen the single coated filter on amazon.co.uk for £80 and the multi coated for £135

is the multi coated really worth the extra money?

also these were on amazon site but not off official amazon just a seller from it, anyone got a better place to pick one up? needs to be 77mm

As I said in the other thread, I don’t have any experience of the Multicoated one, But the Single Coat one has worked a treat for me.

Did you buy from amazon itself or a amazon rated seller?
