I bought a set of Fotodiox macro extension rings to help improve my macro imaging capabilities and so I conducted a brief indoor experiment to familiarise myself with them.
It is important to note that none of the images below have been cropped.
Using my Canon 60D camera with Tamron 70mm - 200mm f/2.8 zoom lens, I took the first picture (at 200mm) without the rings, at close to the minimum focus distance of 950mm:
I then added all three Fotodiox extension rings (7mm + 14mm + 28mm = 49 mm extension), which have no electrical connection and thus the camera can only be used in 'Manual' mode. The rings have no optics either but enabling me to focus the camera considerably closer to the subject than was allowed without them. This was the result:
Here are two other experimental images taken with the three rings attached. First my PC on/off power button:
and my gold watch:
The next step is to go outside and start snapping little critters in the garden to see how it really improves my macro images. What will they think when they get my Tamron lens shoved within a couple of inches of their hairy antennae?

I was told the delivery would be one month from Fotodiox via Amazon.com - but surprisingly the goods arrived in less than a week.
