I’m a beginner and have a Canon 40D with a lens of 28-135mm I would like to buy a 67mm Circurlar polarizer lens filter and am wondering what other info I need to know before buying it? I would like to use this for landscape photography to enhance the colours.
thats pretty much all you will need, just make sure that you get a good one, Tiffen and Hoya are both good filters- i actually ordered a couple the other day from http://www.7dayshop.com . they are actually having a ‘clearout’ at the moment so it’s worth taking a look some good bargains to be had.
