today i packed a lowe pro 35L. maybe that isn't the exact name but i am too tired to remember it right now. carried 70-200, sig35, tok 16-28, 24-105, and 85 1.8, and a flash and triggers just in case.
I shot 90 percent of my (real estate today) shots with my tok 16-28. Typically I have that lens mounted when I show up and only put another on when needed. shot 5 properties today, used the 35 and 70-200 some and the 24-105 a little less. Never put the camera in the bag without a lens on it.
Regardless, i almost never put my body cap on my 6d. It is insanely rare ... only the kind of thing where i want to put the lens that is on the 6D on my back up and am too busy to put something back on the 6D. Or maybe I'm just leaving it at home.
back up body has body cap on it 90 percent of the time.
