A Soligor teleconverter is a negative (diverging) lens (or lens system) which can be placed between the camera and the (removable) lens and thus increases the focal length of this lens. The angle will be reduced and the effect is the same as of a telephoto lens.
A 2 x teleconverter increases the focal length of a lens 100 mm to 200 mm. Because the unchanged close focus range remains the same, one gets a corresponding larger magnification ratio with a teleconverter . Teleconverters are an money-, space- and weightsaving alternative for a telephoto lens.
