Does anyone use the filter wallet things? I just wanted some other opinions before I buy one. I am looking at the Tamrac wallet that holds 8 filters or whatever. My concern though is, are the filters protected enough? I think each filter would have its own little pocket but would they still get scratched? My concern is mostly for my R72, it seems so delicate but the wallet would be much more convenient. If you don't use a wallet, what do you use? I have just been keeping them in the hard plastic cases that they come in but space is becoming a problem in my bag. What do you think?
