Yes. Yes. Definitely!
Thing is, sometimes, you don’t have the luxury of changing lenses. There’s simply no time between shots as in the case of event photography. Event photography is one of the most demanding. Every single moment counts.
Most photographers, like me, prefer to carry two cameras at the same time: one with a wide angle lens, and one with a lens with further reach.
I use the Black Rapid Double Strap to accomplish this
The double strap allows me to hang two cameras by my sides at all times. They attach with a little nub that attaches the tripod thread on the camera. Then it attaches with the hooks and then its secured the hook because it locks.
What’s so amazing about this product? Why do I use it on the majority of my shoots? It allows me to have two cameras by my side all the time. It also distributes the weight evenly, meaning that it won’t take such a toll on my neck. Most importantly though, it allows both of my hands to be free.
As I said, with two camera bodies, most photographers prefer a wide angle lens on one side and a tele lens on the other side. I usually have the 16-35mm f/2.8 on one side and the 70-200mm f/2.8 IS II on the other side. It’s either this, or for lower light situations, I’ll have a 35mm f/1.4 on one side and either an 85mm f/1.8 or 135mm f/2 on the other.
Two camera bodies are definitely something to consider the next time you go out for a shoot. It saves you the trouble of so many lens changes. That in itself should sway you into using two cameras. Less lens changes means less chances of missing the shot, and less chances of getting your camera sensor dirty.
