Due to the generosity of Andrew Purdam, I now have a reverse lens mount (52mm to EF mount).
This was stacked with a 52 to 58 mm step down ring I had lying around.
These three shots are test shots using different lenses.
The 18-55mm kit lens provides the most magnification. I'm not sure if this is because of the 52 to 58 mm step down ring moving the lens further out from the sensor, or a quality of the EF-S lens build.
