The One Series.
The first Olympus E-series camera, hiding behind the first Olympus PEN. Like an elephant hiding behind a twig. I took this image to show the difference in size, which was the main reason to quit using DSLRs.
Both cameras have been used a lot (and have their battle scars), but are now semi-retired. They're no longer daily drivers, but once in a while they are still used.
