Kooka KK-E47 Macro AF Extension Tube Kit

Kooka KK-E47 Extension tubes are designed to enable a lens to focus closer than its normal minimum focusing distance and are useful for macro photography with non-macro lens and allow you to convert almost any lens into a macro lens while maintaining its original optical quality. Extension tubes without no optics, mounted between the camera body and lens to create more distance between the lens and film/sensor plane. By moving Extension tubes, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus.
