Make use of select M42-mount lenses on your Sony Alpha E-mount camera with this Lens Mount Adapter from FotodioX. Precision-crafted out of hardened anodized aluminum, the adapter provides a secure and solid camera-to-lens connection. Additionally, it supports focusing to infinity.
Lens Compatibility
However, if your M42-mount lens has no aperture pin, tabs, or levers; or if it has an aperture pin that does not fully depress (small tabs stick out), it is considered a type-1 lens and is compatible with V1 adapters (available separately).
