Nikon just released a new version of its camera-mounted slide digitizer, the ES-2. For about $140, it’s a barrel that mounts to either a 40mm or 60mm Nikon lens, with a slide tray and a film negative strip holder. Looks like it’s getting decent reviews, and only recently has it actually been in stock. As I’ve mentioned before, my Dad shot slide film almost exclusively so we’ve got boxes of family history waiting to be digitized. I’d have to buy an appropriate lens to match as well, but it’s a lot better than $2K for a dedicated machine.
