I needed a way to be able to switch quickly between 2 cameras when shooting; So each "to park" one while the other is in use. For this to have one or two lenses and a flash hand, is a big advantage. Nevertheless, I have to keep moving, run, kneel, can sit ... Have I therefore bought the Lowepro Outback 100 waist bag. The bag "served its purpose", but 100% happy I'm not so. 1. The waist belt is attached to deep in the pocket. In weight in the bag this tends top away from the body to tilt, thus the lower part comes at the same time closer to the body, and the compromised when running. 2. Once the flash is attached, the camera may no longer deep enough "slipping" in the quiver, so the zipper could be at least half closed. The camera holds no longer really in the pocket and must separately - by Halsgut around the arm -. Be secured (with a cutout for the front Blitzschiene could be bypassed.) 3. The two quiver for interchangeable lenses in my opinion, although large enough (can be equipped with fixed focal length 135 or 50 or 85 or lightning), but as "stupid" verschnallt with the straps that keep these belts always taut - ie once the Lens is taken from the quiver, the belt pulls the quiver together something so that the insertion of a new lens can no longer be done with one hand.
Belted and for example it is equipped small for a stroll a pleasant bag that can be worn nice and you hardly feel to carry weight. When worn sideways, you can thus also Kneeling well, sit down and get up again. I (now) keep the pocket, because I have so far found no real alternative - bags that offer more space and are easier to use, if necessary, are the same lot bigger and restrict the mobility a violently. Since then the usual equipment Backpack better to wear, but is too unwieldy just for "rapid change".
