Here's the bag with just the quick-draw flap opened. This allows for access to the camera (with lens attached), commonly used lenses to either side (70-200/2.8 to the left, 10-20/4-5.6 to the right) behind a set of padded "doors". This is a left-swing configuration so in use the bag would be facing me like this with the camera pointed down and the bag going across my chest. Here the straps are configured in what I call "hybrid" mode. This allows you to have the quick-draw convenience of a sling bag and the comfort of a backpack. Essentially you would wear the bag as a sling but if it got uncomfortable or situations arose where you will temporarily need a more secure carrying configuration (ie. running to catch a bus), you can withdraw the "other strap" and criss-cross it over the strap already being used. This can be done on the fly without taking the bag off your back. You can also withdraw the waist-straps for an even more secure and comfortable way to wear the bag. I have found that this configuration is not quite as comfortable as a traditional backpack configuration but it can be "entered" into on the fly. The great thing about this bag is that you can go from this configuration to a traditional backpack configuration on the fly as well. You just have to be careful when you're unbuckling and moving strap attachment points.
