The use of a range extender, installed between a lens and a camera, will extend the focal length and increase the effective aperture (F/number) of a video lens. For example, using the 2XE range extender will extend the focal length by two times (2X) and double the effective aperture of the following lens:
(2X) 50 mm, F/1.3 lens = 100 mm F/2.6
We also offer an extension tube kit, which allows you to turn standard fixed focal length lenses into macro lenses. This kit includes six extender tubes
(0.5 mm, 1 mm, 5 mm, 10 mm, 20 mm and 40 mm) for extension from 0.5 mm to 76.5 mm. The tube(s) mount between the camera and the lens, making it possible for you to focus a C-mount lens at a much closer distance than normal.

Close-up Lenses (for use with Fujinon lenses only)
Fujinon close-up lenses may be screwed to the front ring of your lens when you need to move closer to a subject than allowed by the minimum object distance (M.O.D.) of the lens.
The Fujinon model number of the close-up lens designates the maximum image-to-lens distance at the telephoto end (in cm), as well as the filter diameter of the lens.
