A few folk have asked about a macro rig that I'm putting together so here it is.
From right to left;
30D....EOS-FD adapter plate.....15mm FD tube.....FD Auto Bellows....25mm FD tube.....lens adapter plate.....20mm f/3.5 Canon macrophoto lens.
Tubes can be added at either end to increase magnification but in the configuration shown then it should get close to 20x. The LED ring light assembly is a 48 by 5500k variable intensity set up although the minimum light distance is just a little too far out at the moment and a better one is under construction.
The front element is mounted in a chamferred extension to allow the light source to come from behind the lens and this is essential with a working distance <10mm.
Initial shots showed the lighting limitation but I got as far as 2mm fitting across the sensor width. DOF is "quite thin" .
