Laowa's Magic Shift Converter converts a full-frame Canon EF mount lens into a wide-angle shift lens on Sony E cameras.
It's designed to convert the Laowa 12mm Zero-D Lens to a 17mm lens on a Sony E camera, but it can also be used to pair any EF mount lens with Sony E models.
With a 4 element optics system and compact build, this is particularly useful for architecture and interior photography.
