During my photo group's annual swap meet, held each February, I picked up a new to me set of extension tubes. I attached my 50mm f/1.8 lens and set to work on a CD with water drops. I am extremely happy with the results.
As a comparison I am including a similar image that I shot using a 40mm lens and Hoya 1+, +2, +4 diopter macro filters.
