The IR lens would be a bit of a problem trying to match it to a modern camera, for starters it has a 52mm screw thread so I don't know if there are any converters out there. As you know, modern DSLR cameras have bayonet fit lenses which to me rule out any possibility of this lens being used, but I've also learned to never say never in this game. Maybe someone will pop up to say "I know where you can get a converter". The 0.42x suggests that this lens could be only half life size too. I think you need a 1:1 ratio to get true life size. Anyway I saw one on ebay for $25 dollars. All the best.Mike.
