Extending the distance between the lens and the film or sensor, by inserting either extension tubes or a continuously adjustable bellows, is another equipment option for macro photography. The further the lens is from the film or sensor, the closer the focusing distance, the greater the magnification, and the darker the image given the same ...
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:
In June 2017, the list is supposed to be complete including 201 past and present lenses, additionally 28 compatible teleconverters and three lens extension tubes with support for integrated autofocus-motors. Listed here are nearly all recent autofocus-lenses, because all manufacturers have included focus motors in their Nikon-compatible lenses ...
The "macro cine copy X" is a macro lens with specific windows to take copies from 8 mm and 16 mm films. The "microscope adapter X" to adapt the camera body to a microscope. A "reverse adapter X", that can be mounted with an extension tube. A classic "teleconverter 2X". Fuji Photo Recorder back.
On August 29, 2017, Canon announced the TS-E 90mm f/2.8L MACRO, the fellowship of the TS-E 90 mm f/2.8. Main difference compare to the TS-E 90 mm f/2.8 is the Macro capability and the change to the L line. Macro photography is possible up to 0.5× magnification with lens only and up to 0.82× with Extension Tube EF 25 II. The closest focus ...
