I use professional cameras and lenses. They are not consumer or amateur level.
My camera and lenses are weatherproof and are solid in construction. I use 2 cameras, that I carry all the time. In my equipment bag I carry 2 Pro Cameras, 2 Flashes, 2 Pro Zooms, Macro Lens, Standard 40mm Lens f1.2 (very fast lens), Medium Telephoto 150mm f1.8 (very fast lens), tripod.
If shooting indoors I also carry light stands, diffusers, backdrop support rig and two to three backdrops.
