Extension Tubes

Canon's extension tube's are exclusively designed for doing very close-up work with Canon EF auto focus lenses, macro lenses in particular. They enable high magnification close-ups of small subjects such as flowers and insects. The tubes have electronic contacts to enable signals between the camera and lens which lets you use the camera's focusing and exposure settings.

A set of tubes that attach between the SLR camera body and the lens and allow the lens to focus closer than normal. They come in a set of 3, which can be used individually or together to vary the focusing distance to the subject.

The Olympus extension tube is compatible with the Olympus 14-45mm, 14-54mm, 40-150mm, 50-200mm, 50mm, 150mm and 300mm lenses and allows the lens being used to focus closer than normal.
