My pre-AI Nikon F2/DP1. Saved my pennies and bought it new in 1974. Used it yesterday for some fall colors (Provia, not Kodachrome... <sniff>).

Took it in for a CLA several years back. First one ever in 30+ years. The camera repair tech had it ready two weeks later. I came in to pay and pick it up, and he apologized to me for taking my money. He said the camera really didn't need a CLA. The lubricants were fine. The meter was right on. The shutter speeds were within factory tolerances. He felt guilty so he had gently tapped out a few dents and dings here and there since the covers were off anyway. He said not to expect him to be alive for the next CLA.

How can you not love that...?
