Camera case for LX7?
As I creep closer and closer to making the jump, I wonder if I need a form-fitting camera case for the LX7. I have a commodious and well-cushioned back pack for serious travel, so I don't need one for major forays. But is it advisable to get one when I'm just traveling light, so to speak? It would still fit in a sports coat jacket outside pocket with the case on, but there would be no chance of it fitting in a pants pocket. Of course, the LX7 might be too big for that anyway!
Thoughts? and if I did get a case, is a cheap one ok?
