Can you install a CS-Lens on a CS-Mount camera with a 5mm spacer ring?

In the context of camera equipment, particularly when dealing with CS-Mount cameras and lenses, it is important to understand the compatibility between lens types and mounting systems. A CS-Lens is designed specifically for a CS-Mount camera, which has a specific flange back distance and size.

Using a 5mm spacer ring with a CS-Mount camera would actually prevent the secure and direct mounting of the CS-Lens to the camera body. The spacer ring alters the necessary focal plane required for the CS-Lens to function properly.

As for the options presented, indicating that it is false to say that a CS-Lens can be installed on a CS-Mount camera with a 5mm spacer ring accurately reflects the technical limitations of the equipment. This underscores that without proper alignment and mounting specifications, the lens may not focus correctly, leading to optical issues. Therefore, the assertion that the answer is false is supported by the foundational principles of photography and lens compatibility.
