The gray 515 Compact Zoom Pak Holster Bag from Tamrac is designed specifically for most film and digital SLR cameras. It will hold an SLR camera with a lens attached (up to 4.25" long). A large, zippered, front pocket holds memory cards and batteries using Tamrac's Memory & Battery Management System that uses red flags to identify available memory cards and batteries from ones that are used up. A pocket inside the top holds items like filters, memory cards, lens caps, and cleaning tissue. The shoulder strap is adjustable and removable so that the bag can be carried on the belt as a holster.
