No typo. The film is Firstcall 400S (same as Rollei Retro 400S) and it's rated at 40 ISO for development in Spur's HRX and Acurol-N. The macro lens has a stellar reputation outwith it's close-focusing range. Mike Johnston said this about it, "Here's one lens that's utterly forgotten yet absolutely magnificent: the Olympus Zuiko 50mm f/2 Macro. You can use it as a normal lens and I promise you, you will never use a better 50mm. No matter what name is engraved on the barrel." You can read the whole article here but be warned that you might find it a bit pointless, too.
