Back in 1983, I employed a guy who's second job was a freelance photographer working for many of the Fleet Street newspapers. Today, you would call him a Paparazzi but he was known to us as Super Kev.
One day, I looked inside his camera bag and was horrified to see two Nikon F3 camera bodies and an assortment of lenses all jumbled up together with no body or lens caps fitted at all.
When I asked him why he treated his expensive gear like this, he answered with a question.
He said, you're a mechanic aren't you, so do you wrap up your spanners in cotton wool ?
I replied of course not.
Well, he said, these lenses & camera bodies are my spanners and I can reach inside my bag, select a lens by feel and attached it to a camera body while I am running down the street after a possible exclusive photograph - smudges I think he called them.
Then he told me about some of his scoops and I was very impressed.
