The SIRUI Jupiter full-frame cine lens series is available with either Canon EF or PL mounts and can be easily adapted to use on Sony E or Canon RF mount cameras.
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 much image quality.
Given the case of using heavy lenses with a lot of accessories attached in front, a mount adapter base with built-in 1/4" screw hole are designed to keep the whole setup in balance, providing effective protection for the lens and the adapter of the camera.
How to adapt EF mount to E/RF mount:
Align the red dot on the adapter with that of the lens mount, then twist the lens counterclockwise until it hits the end.
How to remove:
Push down the button and twist the lens clockwise.
How to adapt PL mount to E/RF mount:
Align the red dot on the adapter with that of the lens mount, then twist the blue ring counterclockwise until it hits the end.
