Vintage M42 Macro Extension Tubes by Pentacon - Review and Test with Samsung NX1000 and Helios 44-2

You can find these M42 extension tubes between $15 and $30. They are very high quality, screw/unscrew smoothly, do not leak any light... Paired with the 44-2 they produce high quality macro images. Recommended!
