Vintage Olympus Extension Tube 7, 14 and 25 Set OM Fit (Vg)

Olympus Film Cameras Extension Tube Set for OM System. 

Want to try macro closeup film photography? These extension tubes fit between your Olympus OM-1,OM-2, OM-3, OM-4 or OM10, OM20, OM30, OM40 and an OM fit lens. 

Olympus extension tubes work by creating space between the lens and the camera's film, which reduces the lens's minimum focus distance and magnifies the subject for macro or close-up photography. No glass is involved in the tube itself; it simply increases the distance the lens is from the film. This allows you to get closer to your subject, fill the frame with more detail, and achieve higher magnification than your lens would normally allow. 

Turns almost any Zuiko OM lens into a macro lens.
