[Leica] Advice on filters

[leica at web-options.com (Bob W)]

B+W and Heliopan are good brands. Hoya do some high-end filters too. I'd
imagine Rodenstock are up there as well. You can buy perfectly clear filters
whose only purpose is protection, otherwise use UV or (if you have a M8)
UV/IR.  

You're likely to get little kids' fingerprints on the front element too. A
lens hood might do something to help prevent this.

Where are you going?
