This FotodioX Pro Lens Mount Adapter allows a Contax-Yashica mount lens to be used on a Canon EF or EF-S mount camera. It is designed to support focusing to infinity and utilizes a brass lens mounting ring to provide a durable, yet lightweight camera-to-lens connection.

A Generation v10 chip built into the adapter enables focus confirmation within a Canon EF or EF-S mount camera when used with a Contax-Yashica mount lens. This feature allows focus to be quickly and accurately achieved through a compatible camera's viewfinder or live view feature.

A: While the FotodioX Pro Lens Mount Adapter with Generation v10 Focus Confirmation Chip for Sony A-Mount Lens to Canon EF or EF-S Mount Camera will work with your lenses from the Minolta Maxxum 5, it will not work with your camera.
