Query: Perfect for light/medium usage

The backback is great for toting a single body with medium sized lens. When packing for long or short distances, I can carry three lens (70/300, 28/135, 17/55), a few filters, spare media and batteries. Comfortable. My tripod (5 pounds) can fit in the velco straps, but I've modified it a bit for longer treks.
