some general macro tom-foolery

[qleak]

This is with my 11 year old sony dsc-f828 (bridge cam). I have a pentax-a 50mm f1.7 reverse mounted on it. I've previously shot a ruler to get an idea of how large the magnification ration is, it's approximately 1:1 to a 8mm sensor. It gives a hard vignette due to the image circles not lining up correctly. Comments welcome

The second one is quite interesting! What is it?

swiss army knife cork screw. I'm glad you like that one, I spent the most time setting it up.

The others were actually handheld... it's pretty fun that the results using this setup are just about as good handheld as on a tripod. I am, of course, using a flash.
