Questions tagged [extension-tubes]

An extension tube - is used with interchangeable lenses to focus closer, useful in macro photography. The tube contains no optical elements; its sole purpose is to move the lens farther from the image plane. The farther away the lens is, the closer the focus, the greater the magnification, and also the greater the loss of light (requiring a longer exposure time).
