N120 Extension Ring 50 II

This is the N120 Extension Ring 50 II, a 50mm extension for the N120 port system. It adds 50mm of length between your housing and port, allowing for longer lenses that would not otherwise clear the port.

Machined from anodised aluminium alloy, the extension ring maintains the N120 seal integrity. It attaches with the standard bayonet mount and features a locking collar for security. Use this extension to achieve correct focal length positioning for your lens, ensuring corner sharpness with wide-angle optics or proper close-focus distance for macro setups. Verify the necessary extension length for your specific lens and housing configuration using the compatibility finder.
