If you are like me you when you think of where to go on vacation you are thinking of all the amazing photos you can capture. You won’t want to leave your favorite camera and lenses at home so you need an inconspicuous bag to carry them in. You can go the backpack route—there are a lot of companies that make backpacks specifically for cameras. Local camera stores should carry either the Lowepro or the Tamrac brand so you can see them for yourself. I have a Lowepro, it works fine, but for me it is a bit bulky moving around town.
If you are looking for something more discreet and less obtrusive especially for walking around town check out the ThinkTank Urban Disguise line. The Urban Disguise bags come in six different sizes and are all black so as not to call attention to them. The design looks more like a shoulder bag and you can wear it across your body so it doesn’t slip off of your shoulder. I have some other bags by ThinkTank and have been really pleased with their practical nature and ease of use.
