Do any of you that shoot with 2 camera bodies?
I routinely shoot weddings with two camera bodies and keep a third as a backup.
For stage performances, I usually shoot with three bodies... one with normal lens, one with telephoto lens, and one with wide-angle lens.
I sometimes shoot documentary and street with two 35mm rangefinder or SLR bodies... rangefinder with 35mm f/1.4 and 90mm f/2 or the SLR with 35mm f/1.4 and 85mm f/1.4.
For walkabout / hiking type photography, I usually carry only one lightweight camera body and one lens and shoot either black & white or color.
For nature hikes, I usually take one body and one macro lens and shoot only color film.
At one time, I shot vacation travel with 2 Contax G1 bodies and 28/45/90mm lenses or 21/45/90mm lenses.
I now do vacation travel with one camera body, one lens, and one smart phone backup.
On my bucket list is to do a Grand Canyon type vacation with two medium format cameras... one Fuji 6x7cm with 90mm normal lens and one Fuji 6x9cm with 65mm wide-angle lens.
