J at Red Clay Soul did a post a while back about transforming a Filson bag into a camera bag. I liked that idea quite a bit, especially since I've already outgrown the bag my camera came in.
This is the one I got.
I put it in my Filson Passage laptop briefcase.
Pretty awesome. I've got extra room for other lenses (and even the Pentax film camera my dad gave me today).
Thanks for the tip J.
