I'm Going (extension) Tubing, He Bellows

Some long lenses have a minimum focus distance as large as 30 feet... who thought that was a good idea? Put more space between the sensor and the rear of the lens and you can focus much closer. This challenge is for shots, macro or otherwise, made using a lens mounted on any type of glassless extension: tubes, bellows, an empty toilet paper roll and duct tape.... ;)
