Make use of your existing Contax 645-mount lenses on your Sony Alpha E-mount camera with this Pro Shift Lens Mount Adapter from FotodioX. Precision-crafted out of metal and featuring chrome-plated brass mounts, the adapter provides a secure and solid camera-to-lens connection with no play, gap, or wiggling between the elements. The adapter's design allows the lens to shift 10mm in each direction and rotate 360°. Integrated into the adapter is an aperture iris, enabling you to adjust the amount of light reaching the lens and allowing for some control over the depth of field. Additionally, this lens mount adapter supports focusing to infinity.
Note:
This is a manual adapter. It does not support lens functions that rely on electronic communication with the camera body.
