I Converted A LENS DOUBLER Into a MACRO TUBE

Extension tubes are an easy way to get into macro photography for cheap (Wikipedia’s explanation) The idea of DIY this 2x converter into a macro tube when my old Sigma Doubler that got broken for some reason. This is not a step by step video tutorial, has this process is so simple, and might vary from different models. BUT surprise at the end this extension tube work did work better than I was expecting.
