A Polaroid Land Camera Swinger Model 20
A good brand epoxy glue
A set of Canon EF Macro Extension Rings. I just got some cheap ones. Mine has 7,14 and 28mm. written on them. Others has numbers 1,2,3 on them. Get the 7,14 and 28mm. ones if you can. I don't know if the others are the same size. You should get this with the AF-Confirm chip installed.
Some Canon EF Macro Bellows. Again I got the the cheap stuff. You should get this with the AF-Confirm chip installed.
A Phillips head Screwdriver
A Compass. This is for drawing circles, not for finding the North Pole
A Ruler and a Vernier Caliper.
A flat black piece of plastic sheet 5x5 cm. You can get this from smashing the remains of the camera body.
A flat black permanent marker. I used a Posca marker.
Note: AF-Confirm is when your normal AF lenses, confirms that you have reached focus. This is pretty handy, so get your adaptors with it.
