Tokina 135mm f/2.8 M42 to Sony E Adapter 3D Print – Mirrorless Lens Mount

3D printable M42×1 to Sony E-mount adapter designed for the Tokina 135mm f/2.8. This adapter allows you to use the Tokina 135mm lens on Sony E-mount cameras such as Sony a6000, a6300, a6400, and Sony A7 series. The adapter has a 27 mm height, which was carefully tested to provide correct focusing across the full range — from portrait distances to infinity focus. To improve stability, the bayonet interface is intentionally designed with a slightly tight fit, helping to reduce play between the adapter and the camera mount. This minimizes wobble and provides a more solid connection, which is especially useful for astrophotography and telephoto lenses.
