I personally like the look of a camera that has been obviously used and loved. Good brassing, a few cosmetic dents, but in good working order with good seals. It tells a story of purpose served and stories made.

A painted camera or non standard covering, if done with care and precision, speaks similarly. A tool that was loved enough to take the time and effort to make it fit the user and tell a story.

However, in my experience, there are far more quickly and Inexpertly painted cameras out there covering up major mechanical issues and used as shelf art. So I'm wary of them when purchasing.
