I carry the bag on a steroid Belt Thinktank along with some Lens Changer bags. I think this bag very well thought out. My EOS 7D incl. Battery grip with attached standard zoom (17-40 L) fits loosely into the bag. I have attached a greater appearance, can extend through the expansion zippered pocket down. So I can even transport the camera with EF 300mm f / 4 L IS USM in your pocket. I especially like that the opening of the bag is away from the body. Thus one arrives always optimally adapted to the equipment. In the lid opening a separate compartment is incorporated, which is fine for filter. I have in a Cokin filter holder and a graduated filter housed, when I'm out in the field landscape photography. The stretchable in the front pocket is great for recording of lens or camera cover when changing lenses. Rounding out the item by the handle. A valuable aid when you want to separate from the belt the bag times or simply as the transport. Not to forget the rain gear that is easy to grip housed in a zippered pocket on the side. All in all, a well-rounded, top handles and just practical. Certainly not my company think tank last product. Thoroughly recommended!
