Homemade Macro adapter makes 1:1 macro pictures

Last year I purchased extension rings on a flea market for using ordinary lenses as macro lenses, but these extension rings have problems with the bayonet as they sometimes cannot be released properly. To prevent damage to my brand new 6d or lens I abandoned these and made a simple plastic one myself made from rear lens cap and body cap.

Just a 40mm PVC plumbing tube of 75mm long, a body cap, a rear lens cap and PVC glue is enough. When glued together (and cured enough which takes several hours) it is an excellent extension tube.

Using the 24-105 f/4L (zoomed in to 105) I could achieve nearly 1:1 and with the 50mm 1.5:1.

To squeeze the aperture something is simple: mount the lens on the camera normally, select Av, set to f/8, press the DOF preview and simultaneously unmount the lens, so the aperture ring keeps 'frozen' at f/8 (until you remount it normally).

Then mount it again with the extension ring. Of course, AF and aperture control won't work, so use MF. When on P or Av, the camera sets the exposure, otherwise this must be done manually as well. Aperture will show 00.

Photos were taken with CFL light at ISO 12500, AWB and f/8 (ISO 12500 works well on a 6d).
