>>2849118Speeds 1/30-1/250 + B, coated triplet f/4,5 lens with swirly bokeh, up to f/22, focusing via loupe on ground glass patch. It's barebones and awful, designed for slower film in mind.
It's basically the simplest and most rugged/compact way of exposing 120 film that's not a pinhole coffee can. Nothing beyond that, but at ~$40 a pop fully servicable for daylight handheld shooting and B tripod/propped up lowlight. Built in timer helps.
