I was on my way home from shooting ducks, when I had to slam on the brakes to avoid hitting a teenager on a push bike. I was literally two minutes from home. Camera (5D2) and brand new Sigma 150-600mm Sport Lens on the back seat of the car went flying off the seat. I don't believe there is any damage, but is there a general check I can do to make sure everything is how it should be? I have taken some test shots and all looks OK.

I generally keep the camera and lens, I am using at the time, close by me in the car. No carry bag. Maybe this is a lesson hard learnt?

Any advice on checking the camera and lens, or comments on how you carry your equipment is much appreciated.
