FotodioX Pro Lens Mount Adapter for M42 Lens to Nikon F Mount Camera
Make use of select M42-mount lenses on your Canon EF- or EF-S-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.
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 this V1 lens mount adapter is compatible with it.
However, if the aperture pin of your M42-mount lens depresses all the way down, your lens is considered type 2 and is compatible with V2 adapters (available separately).
