The ALPA extension tubes do not have any optical elements, so they don't degrade the quality of the lens. Of course you do lose the ability to focus at infinity. A macro lens will provide better results due to the fact that they're optimized for close-up work. Extension tubes are used with macro lenses in the same way that we used them in this video.
Great demonstration!

Do extension tubes degrade image quality compared to a macro lens?
