What do you carry your gear around?
At present I have a backpack but I am rapidly growing out of it. I've seen toolboxes on wheels used and these have doubled up as both a seat and a step ladder for shooting over fences.
I use a Citroen Berlingo van. I can comfortably get all of my gear in there with room to spare. Although sometimes I have to get out and walk.![]()

Normal camera bag for jobs where I can drive to a location to set up, and a lowepro backpack for when I can't.
When i used to do more commercial work in pretty industrial and busy environments, I used aluminium flight cases too for protection.
It all depends on how much protection you need, how much walking you need to do, and what's appropriate... and whether it's safe to leave gear in the car or not.
I don't shoot motorsport though.... so others will no doubt give advice based on that environment.
Usually I'll have a camera with the lens I think I need set up and carried, a backpack with spare batteries, cards, etc, it's just now getting to the stage where I am trying to carry enough to cover every situation.![]()
I leave camera bag in vehicle and just carry the cameras about. A photographers vest allows me to carry bits and pieces about my person.
I tend to use either a Think Tank belt system witha couple of pouches and just carry the camera/s or a large backpack.
The trouble I find with the Think Tank at least on the speccy side is either when the weather is going to wet/heavy showers (a normal summers day then) is carrying all the extra gear e.g. rain coats, waterproof covers for camera and lens and to that the (at some tracks) essisantial stool/steps it can get a bit unmanagable. And if your at certain tracks (donnie & Silverstone) on pratice/qualifying days you have to carry enough water/food if you venture away from the main areas as noramlly the refeshment places are normally closed.
the weight of gear and water bottles (I live in Australia) will drag it down,
