Extension tubes are sometimes confused with teleconverters, an optical component (i.e., containing lenses) designed to increase effective focal length. A close-up lens also enables focusing closer for macro photography but, unlike an extension tube, a close-up lens actually is an optical element.
The EF 100 mm f / 2.8L Macro IS USM lens is the second macro lens in the Canon L series. It incorporates IS, improved build quality, weather sealing, and a new lens configuration resulting in improved MTF plots. This is the first lens on the market to incorporate Canon's new Hybrid Image Stabilization Technology.

The other Canon FD macro lenses achieve only a 1:2 (half life size) magnification without extension tubes and require the lens to be closer to the subject; on the other hand, the 200 mm's shallower depth of field at equivalent aperture settings can be limiting.
Many macro lenses are characterised by a high amount of chromatic aberration, especially when using reversed-lens, extension tube or close-up lens. Some macro lenses, called apochromatic lenses , are designed to better control this, such as the Laowa 100mm f/2.8 2x Ultra Macro APO and the Sigma APO MACRO 150mm F2.8.
