Do you want to have one bag for your camera and personal travel stuff? Or just a small camera bag separate from other bags? The Think Tank Retrospective 5 will easily fit the camera and three lenses, and a couple of spare batteries and filters. It won't fit much else. I've been using the TTP City Walker 20 this summer, and it carries my whole Fuji kit (2 bodies 4 lenses) plus it has room for guidebooks, a water bottle, my glasses, an umbrella, etc. That's my preference for travel.
