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:
A kit lens can be sold by itself outside of a kit, particularly the ones that are moderately expensive; for instance a kit lens included in a prosumer camera kit is often marketed as an upgrade lens for a consumer camera. In addition, retailers often have promotions of standalone low-end camera bodies without the lens, or a package that bundles ...
In photography and videography, a matte box is a device attached to the end of a lens in order to prevent light leakage. It performs and mounts essentially the same as a lens hood, but usually includes adjustable fins called French flags. Another purpose of a matte box is to hold filters in place in front of the lens. Some are supported by two ...
The insertion of a converging lens in front of the taking lens reduces the focal length of the combination. Close-up lenses are usually specified by their optical power, the reciprocal of the focal length in meters. Several close-up lenses may be used in combination; the optical power of the combination is the sum of the optical powers of the ...
Fujinon XC 16-50mm f/3.5-5.6 OIS: This lens is a consumer-grade standard zoom, covering wide angle to short telephoto, equivalent to 24–76 mm on a full frame camera. The lens is the 'kit' lens for the X-M1 camera, and has a lower end build quality than the other Fujinon lenses, while maintaining good optical quality.
A photographic lens or objective is an integrated system comprising one or more simple optical lens elements, which produces an image of a distant object. The main article for this category is Photographic lens .
