FotodioX Macro Extension Tube Set for M42 Screw Mount System Cameras

The Macro Extension Tube Set from Fotodiox lets you convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality. By placing distance between your M42 camera body and screw lens, focusing distance is shortened and the magnifying effect of your subject is created. Macro tubes increase the lens-to-sensor distance, allowing for closer focusing than normally allowed by the lens. The greater the length of the extension tube, the closer the lens can focus. This means you can get macro performance without needing to switch to a specialized lens, and you will retain all the normal benefits of your optic when the macro function is not in use.
