Today I received my macro reverse ring via ebay. It is a DSLR adapter that lets you flip your regular lens back to front for shooting macro. The most striking result is when you take a wide lens, or zoom wide, as it lets you get really close to the subject.
After going outside to try to shoot flowers and plants on a windy day, I found that the opposite was more useful, that is the table top. After experimenting, I found that high F with longer exposure works best to overcome a very intolerant depth of field, so keeping very still was key.
My conclusion is that this is not something to bother with for general close ups and everyday macros. But considering that the ring adapter costed under $10, it is worth having it in the gear bag for when a relevant opportunity comes up.
