Hi there, I was curious how you folks carry your filters around. I have a Tiffen wallet, but it's big and also I'm not confident it will always isolate the filters from each other. I did buy some metal end caps to try the "dense pack" route; but if I buy any thin-mount filters that won't work (since those generally don't have front threads) - plus I get a bit paranoid when I'm trying to screw two expensive filters together. Maybe I'm just clumsier than average, but lining the threads up correctly is sometimes a chore for me. Do any of you own the Kata accordion filter pouch? On a related note - how do you carry your rectangular filters, if you have any? (I don't, currently; but I'm thinking about picking up some graduated NDs reasonably soon). Thanks for your thoughts and experiences!
