My situation is this as follows. Simply put, I need to make the bag below work for photo stuff now and then when I need to be on a bicycle for long periods of time and also carry bike stuff like a patch kit, rain jacket, etc. The bag: Chrome Warsaw If it comes down to it in the end, I can just shove my shoulder bag inside, but I'd prefer to find a more elegant solution. I will be carrying: Mamiya 645 Pro with winder and prism 80mm f/1.9 and 45mm f/2.8 lenses Canon digital body 35mm f/2 and 50mm f/1.4 lenses 2x 120 backs Light meter Memory cards Compendium shade A metric crapton of film I have very, very little experience with the padded inserts and wraps available. Suggestions would be appreciated. A few things to keep in mind: I'll be on a bicycle Yes, I know it would suck to crash with cameras in my bag, but I've been there, done that, etc Racks/panniers on the bike are OUT No chance of car transport for all practical purposes EDIT: link added on the bag. whoops!
