Optomax 35mm f/2.8

Once I owned an Optomax 35mm f/2.8 M42 lens. It was a lived-in kind of lens with a former owner's postcode engraved into the barrel with a sharp pointed tool. I think there was something growing in it; there was certainly a hair inside, probably an eyelash. But you don't get many 35mm f/2.8 lenses for less than £10, so I gave it a spin and it was pretty decent on a Canon EOS 20D with a bit of post processing. Alas! the quantity of kit was overwhelming my living space. Things had to go. The 20D found a new home via eBay. It was a good camera: the 30D is very similar yet has a bigger screen on the back, and I would like one of those one day. The Optomax went to a good charitable cause. It may be making prize-winning images by now.
