Finding the right bag for the Sigma Dp1. The bag I use for travel and carrying a SLR around is the Lowpro Slingshot. These bags are designed to be carried on your back, but slide to the front for easy access to your camera. The Dp1 is a much smaller camera but having a similar style bag for me is ideal. Now I like to call my camera bag my purse, because I use it for much more than just my camera. The bag I am modeling in the photo is a Roots bag and it is a sling that unlike the Lowpro can be worn over ether shoulder. There is enough room for the camera with the viewfinder, lens hood and lens shade attached. Also in the main compartment I put my sunglasses and a cleaning cloth. The side and front compartments will hold the battery charger and cables. There is a zippered pocket to fit my passport, tickets and boarding pass. Located on the strap is a pocket for your cell phone. Other items I would put in it are loose change, keys and a tooth brush. I am sure I could find a place for a map if I thought I might need it, most of us men don't need maps, right. I also like Roots bags because there is a picture of my friend Bob, on every bag.
