I ordered this bag following my purchase of an Olympus E-500 D-SLR. The main pouch fits the camera with standard lens attached very nicely, while the space remaining beside the lens is perfect for keeping a spare battery and memory card. The quick release clip on the top of the bag ensures that your camera is only ever seconds from being ready, yet the stretchable fabric around the sides seals the whole thing to give at least 'splashproof' protection when closed. There's also a pocket on the front of the bag which fits a battery charger and cable, although the velcro fastener that keeps it shut is a little flimsy.
Overall, this pouch-bag is a neat, tidy and comfortable size for safely storing an Olympus E-500 securely yet ready for use.
