step up (down) rings

Hi all,

I'm thinking I would like a nice circular polarizing filter, and see one on Amazon for around $178. ; It's a B + W Kaesemann 77mm (that will fit on my 10-22 lens). ; I'm not sure what the Kaesemann means, other that it will thin my wallet faster. ; Anyway, I think I would then opt for a step down ring so that I could use this on my other lenses. ; Amazon has three step down rings that take a 77mm down to a 67mm. ; The price changes from about $15 to about $5. ; I know, you get what you pay for, or do you? ; I've never used a ring like that before, so don't really have anything to base a comparison on.

Any thoughts?

Thanks,

Boris

 

I usually go with the "you get what you pay for" approach when buying equipment, but I'm not sure that applies to step rings. ; I would prefer a metal ring over a plastic one (if they even make them in plastic). ;
