I have been interested in macro photography for a while but haven't taken the time or spent the money to get started. After a little internet research, some time looking through what I had on hand, and a couple dollars at the hardware store I was able to put together a setup that I can use to see if this is something I want to further pursue.
What I had on hand were a couple of Tominon lenses (75 MM and 35 MM), a reducing coupling (female side fits the lenses, male side fits tightly inside 1 ¼” pipe) , and a body cap for my camera. The lenses were originally used on the Polaroid MP-3 copy system. What I needed was an 1 1/4" slip to male threaded plastic conduit coupling, and some 1 1/4" pipe.
Extension Tube
Here is another shot of the tube as well as the lenses. I am not sure what the item on the right was intended for but the threads fit the filter threads on the 75MM lens so I am using it as a lens shade.

A shot with the 35MM
The results aren't great but better than I expected when I was mixing JB weld to attach a conduit coupling to a lens cap. I don't know what is causing the uneven exposure with the 35MM lens. I think I will cut a few shorter tubes and see what that does.
