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.
True macro lenses, such as the Canon MP-E 65mm f/2.8 1-5x Macro, Laowa 25mm f/2.8 2.5-5X Ultra Macro (a relatively shorter focal length) or Minolta AF 3x-1x 1.7-2.8 Macro, can achieve higher magnification than life size, enabling photography of the structure of small insect eyes, snowflakes, and other minuscule objects. Others, such as the ...
That distance is sometimes given on the filter in millimeters. A +3 close-up lens has a maximal working distance of 0.333 m or 333 mm. The magnification is the focal distance of the objective lens (f) divided by the focal distance of the close-up lens; i.e., the focal distance of the objective lens (in meters) multiplied by the diopter value (D) of the close-up lens:
Despite the macro designation, the lens can focus to infinity like regular lenses. As such, it is appropriate for use as a portrait lens. This lens can be used with an extension tube, which increases the maximum magnification to 1.19× (EF 12 II) or 1.39× (EF 25 II). In these cases, focusing at infinity is sacrificed, with maximum distance ...
