Well i have an offer from a really ignorant owner for a completely new Cokin filter, he bught the 77mm version but has a smaller diameter lens ...
The price is like 2/3 of the selling price over here .
I would use it with my siggy 10-20 and think that i could benefit from it as here we do get a lot of dull skies and washed out colors, should i buy it or does it not perform very well ?
I mean the visible differences in the color of the skies and vignetting should they be a problem ?
Thanks in advance
