I've seen a few threads about kludging macro lenses, the EF 35-80 mod (http://photography-on-the.net/forum/showthread.php?t=190428) in particular, so I felt like sharing this one. Since a dedicated macro is out of my budget for the time being, I've been improvising. Originally I stacked two 50mm f1.8's face-to-face, but I soon learned that wasn't a very useful option due to the extremely shallow DOF and the extreme vignetting introduced when I tried to stop down.
So I decided to cannibalize a crappy lens I had lying around. I disassembled an Underground OM-mount 80-200mm f4.5 and re-purposed the front element (Which is still in its barrel with filter threads), mounting it face-to-face with a Zuiko 50mm f1.8 which in turn goes on my XT with an adapter. I was surprised by the results.

1/125, forgot f-stop, no flash (~65% cropped)

1/320 @ f8, no flash (~60% cropped)

The DOF seems a little better than the stacked 50's and I can stop down now. The working distance is several inches with the Zuiko set at infinity and drops to an inch or two at the MFD. Not ideal for chasing dragonflies, but still lots of fun.
Maybe I should call it the FrankenMacro?
