The 18-55mm f / 3.5-5.6G AF-S Zoom-Nikkor lens is a midrange zoom lens manufactured by Nikon for use on Nikon DX format digital SLR cameras. Often included as a kit lens on entry-level DSLRs, it also can be purchased separately from the camera body. Nikon first introduced the lens in 2005 and has provided five subsequent updates.
Nine-blade rounded diaphragm; Extra-low Dispersion (ED) glass element to reduce chromatic aberration; Nano crystal coated glass element to reduce internal lens reflections and lens flare; Super integrated coating (SIC) to reduce flare and ghosts. Internal focusing (IF) [2]
Or it may cause mechanical vignetting if the diaphragm is outside of the lens (like a focal plane shutter or apodization filter). The term diaphragm shutter has also been used to describe an optical stop with a slit, near the focal plane of a moving-film high-speed camera. [5] A few types and makers of leaf shutters became very well known.

See the articles on aperture and f-number for the photographic effect and system of quantification of varying the opening in the ...
