The most stable artifacts in my gear collection are the 50mm f/2.8 El-Nikkor enlarging lens that I bought new when it first hit the market in 1962 and the Omega B-22XL enlarger I bought new a couple of years later. Just about everything else in my darkroom was bought second hand decades ago. Hell, I've got dirt in there that must date back to the sixties. Maybe I should head over to the lawn and garden department at K-Mart and pick up a sack of new dirt?
As far as shootin' stuff goes, it's mostly picking up a yard sale bargain here and there. Three M bodies and a CL is enough, and the Bessa L makes a great rear cap for the 15. The last camera that I'd lusted after, from way back in the sixties, was a Brooks Plauble Veriwide 100. A few years ago I got a great deal on a clean one, picked up a brick of 120 film, and soon concluded that it wasn't for me. I fed the 120 film to my Minolta Autocord. I don't need image stabilization, auto focus, auto exposure, or a motor drive. Multi-coating doesn't intrigue me. No GAS here.
