NEW! Super-16 2x Range Extender C-Mount Lens Adapter -- Stops vignetting! 

NEW! NAVITAR OR COSMICAR 2X RANGE EXTENDER FOR C-MOUNT LENSES.
TOP QUALITY MINT GLASS!

This 2x extender doubles the focal length, so lenses that vignette on your c-mount camera sensor will not vignette using this adapter! Features the highest quality optics so you don't lose resolution. 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 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 respectively.

We also offer an extension tube kit in our store and website, which allows you to turn standard fixed focal length lenses into macro lenses. This kit includes four extender tubes (5 mm, 10 mm, 20 mm and 40 mm) for extension from 5 mm to 75mm. 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
