Curt Newbury Studios Stefi 12 Direct
Alternatively, could "Stefi 12" be a model name of a camera or lens from a different manufacturer? For example, maybe the user mixed the names. For instance, the user could have meant "Cooke Optics" instead of Curt Newbury Studios. But then Stefi 12 isn't a model known to me. Alternatively, the user might have a typo in "Stefi 12", meaning "Stefi" instead of "Stefi" as a person or character.
