Spacer Rings - Kowa Lenses

Kowa's spacer ring increases system magnification while reducing the minimum working distance, which is helpful when attempting to zoom in closer when the camera cannot be repositioned. Kowa's spacer ring also enables the user to attach a C-mount lens to a CS-mount camera.
