The Pentax smc D-FA 100 mm F2.8 Macro WR is a macro lens for K-mount announced by Pentax on December 9, 2009. At infinity focus (left) and maximum close focus (right) References
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 ...
Given its unusually high 1:4 (0.25x) image reproduction ratio, the 100mm GM lens can be considered a pseudo-macro lens. Though designed for Sony's full frame E-mount cameras, the lens can be used on Sony's APS-C E-mount camera bodies, with an equivalent full-frame field-of-view of 150mm.

These new lenses included 35–80 mm f /4–5.6 (with built-in lens cap), 80–200 mm f /4.5–5.6, 35–105 mm f /3.5–4.5, 70–210 mm f /3.5–4.5, and 100–300 mm f /4.5–5.6. [ 4 ] Some of the original lenses were updated and re-released with the same cosmetics and are known as "New" or "Restyled" versions; minor optical updates such as ...
The Canon EF 100 mm f / 2.8 Macro USM lens. The EF 100 mm f / 2.8 Macro USM lens is a prime lens made by Canon Inc. It is of the EF lens mount that fits the EOS camera system. There are three versions, the original, a second that adds a USM autofocus motor, and a recently released L series version that incorporates Image Stabilization (IS).
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:
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.
