Athens, Georgia
Several months ago, I picked up some early-1970s Canon gear, including a chrome-nosed 50 mm f/1.4 lens with the metal hood. That hood had some bushings that kept it tight to the lens, but they had both worn out and disintegrated. After some futzing with different materials, I was able to cut some new ones.
I can’t think of a small lens with a disassembleable hood anymore. Or even a metal hood …
