Lensbaby has released a Micro Four Thirds/Sony NEX/Samsung NX compatible Composer Pro interchangeable lens. Like other Lensbaby optics, the Composer Pro features a swiveling design to allow for creative adjustment to focus. Previously only available for full-fledged DSLRs, the Composer Pro is a step up alternative to the Composer boasting metal construction and smooth manual focusing.
The Lensbaby Composer Pro for mirrorless cameras is compatible with the proprietary Optic Swap system and will ship with either standard Double-Glass Optic for $300 or a Sweet 35 Optic for $400. Read up on the Composer Pro at Lensbaby's website.
