The FreePower ET-M Macro Extension Tube Kit is an interesting solution for taking macro photos with M42 lenses and cameras.

The rings placed between the camera body and the lens allow to increase the distance between the focal plane of the lens and the photosensitive material in the camera (matrix) and thus obtain a larger scale of mapping. Due to the lack of optical elements, the rings do not affect the optical correction of the lens. The rings can be used individually or together.
