My oldest camera lens is a 1930s Kodak Astigmat, which will continue to be used occationally (I've made an adapter to use it on my DSLR). Like most photographers of the film days I've used more than a few rolls of their film, once using 10 rolls (over 36 shots on each) in less than a month - though these days 400 shots in a day is not totally unheard of. It will indeed be sad to see them go, lets hope at least a few film & darkroom supplys manufacturers are able to keep going.
