The adapters are constructed with aluminum alloy to be lightweight and sturdy, and fit perfectly with the SIRUI Jupiter lens series. SIRUI E/RF adapters allow you to adapt the lens to the desired mount without sacrificing image quality.
Given the case of using heavy lenses with a lot of accessories attached in front, a mount adapter base with a built-in 1/4" screw hole is designed to keep the whole setup in balance, providing effective protection for the lens and the adapter of the camera.
