I was looking for a good bag for my new Sony DSC W170, and what Actually tempted by Sony's original bags, but the price made me look around for others. Other bags That Claimed to fit all the W series cameras did not fit Actually the W170, but finally I found this one did the camera fits perfectly and can be fixed to a belt with a strap. A good feature, not Mentioned in the description is a small pocket fitting a Sony Memory Stick Duo. The Extra pocket is closed by a separate strap securing the card inside the bag even if it is opened to remove the camera.
