Conclusion 3 of 4
<- A JS drops by to check out my cap.
So when a subject is spotted, I unlock-and-rotate the beltpack to my front to access my camera body, mix-and-match the accessories for the magnification I want with my primary macro lens, and I'm ready to shoot. When I'm settled down in a certain location, I can even remove the beltpack and use it as a standalone.
Likewise in other areas of photography such as action sports, I store a short zoom (e.g. 17-70mm) attached to my camera face down in the beltpack, plus another lens (e.g. 100mm) beside it and a long zoom (e.g. 100-400mm) in a modular lens case attached to the rail on the belt so that I can change three different lenses on the go. I hang my heavier camera setup on the shoulder harnesses to relieve the stresses on my neck.
