You absolutely need to protect your DSLR at all times as one hard bump or drop could spell the end of your investment. The Lowepro Topload Zoom 1 Camera Holster Bag provides adequate protection for your DSLR and one medium zoom lens. There is also room for a few must-have accessories. The great feature about the top-loading bag is you can use the camera whilst having another lens or two in the bag. It is much easier to carry and use this holster bag versus traditional (and heavier) camera bags.
