Worst lens:
A 300mm mirror lens, Canon FD mount, around 1980. Can't remember the brand, Miranda? Or maybe it was a Tamron (don't think so). Not Canon, Nikon, Pentax, Sigma, Minolta, Vivitar...
I don't think I got one good shot with that (no auto-ISO days...), it was soon replaced with a newly released Canon FD 70-210 f/4 which was more useful (though probably not the "best" lens either).
Edit: maybe it was a Makinon 300mm f5.6
