Extension Tube Set (Macro Rings)

【FP-RGST】 6 Extensing tube ring sets

Extension tube set (Macro Rings) are inserted between the lens and camera to shift the focus point further than the mechanical limit of the lens, for close-up applications.
Different length tubes can be used in combination with each other.

  • Note: Extension Tubes are not suitable for zoom lenses. Lens will not track focus whilst zooming.

Macro Focus Mount

Macro focus mounts extend the flange back length by 2mm by replacing the original C-Mount of lens.

Note: Mount screw length is normally 3.5~4mm.
If the use of 2mm of Extension Tube is required, the remaining mount screw is insufficient to mount to the camera securely.
Under these circumstances use of this accessory is highly recommended.



(for FL-BC2514D-VG, FL-CC1614A-VG, FL-HC1212B-VG)



(for mega-pixel lens only)


Attaches to the rear of C-Mount lenses to double the focal length.

  • Note:
    1) When the focal length is doubled, the angle of view halves and the F no. is doubled.
    2) Resolution is lowered, contrast reduced and image sharpness reduced due to decreased depth of field.
       (There is no change in zoom ratio or minimum object distance.)
    3) Range extender cannot be attached if the rear optic protrudes by 3.7mm or more from the flange surface.
