A superzoom or hyperzoom lens is a type of photographic zoom lenses with unconventionally large focal length factors, typically ranging from wide angle to extreme long lens focal lengths in one lens. There is no clear definition of a superzoom lens but the name generally covers lenses that have a range well above the 3x or 4x of a standard zoom lens, with lenses being 10x, 12x, 18x, or above considered superzoom.
Nikon Corporation, also known just as Nikon, is a Japanese multinational corporation headquartered in Tokyo, Japan, specializing in optics and imaging products.
The Nikon DX format is an alternative name used by Nikon corporation for APS-C image sensor format being approximately 24x16 mm. Its dimensions are about 2⁄3 those of the 35mm format. The format was created by Nikon for its digital SLR cameras, many of which are equipped with DX-sized sensors. DX format is very similar in size to sensors from Pentax, Sony and other camera manufacturers. All are referred to as APS-C, including the slightly smaller Canon cameras.
The lens includes vibration reduction to counter camera shake. To minimize chromatic aberrations the lens uses an extra-low dispersion glass element. The lens uses internal focusing and a silent wave motor to focus. Two switches are provided on the lens. One of them can be used to switch vibration reduction on/off and the other is used to switch between auto-focus and manual focus. Like all lenses in the DX format, the 18-105mm casts a smaller image circle than lenses for full-frame 35mm cameras and is therefore only compatible with cameras having APS-C-sized sensors (or vignetting will result).
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.
In optics, chromatic aberration is a failure of a lens to focus all colors to the same point. It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light. The refractive index of most transparent materials decreases with increasing wavelength. Since the focal length of a lens depends on the refractive index, this variation in refractive index affects focusing. Chromatic aberration manifests itself as "fringes" of color along boundaries that separate dark and bright parts of the image.
An internal focus lens is a photographic lens design in which focus is shifted by moving the inner lens group or groups only, without any rotation or shifting of the front lens element. This makes it easy to use, for example, a screwed-in polarizing filter or a petal shaped lens hood. During macro photography, using an internal focus lens reduces the risk of the front of the lens accidentally hitting the subject during focusing as the front element does not move.
There is no distance scale and being a G lens the AF-S 18-105 VR doesn't feature an aperture ring.

Performance
Digital Photography Review praised its high performance saying "The wide zoom range makes it suitable for shooting buildings and scenery while the telephoto zoom range is ideal for portraits".[2]
Digital Photography Review, also known as DPReview, is a website about digital cameras and digital photography, established in November 1998. The website provides comprehensive reviews of digital cameras, lenses and accessories, buying guides, user reviews, and active forums for individual cameras, as well as general photography forums. The website also has a large database with information about individual digital cameras, lenses, printers and imaging applications. Originally based in London, Digital Photography Review and most of its team relocated to Seattle, Washington, in 2010. It is currently owned by Amazon.
The Nikon F-mount is a type of interchangeable lens mount developed by Nikon for its 35mm format single-lens reflex cameras. The F-mount was first introduced on the Nikon F camera in 1959, and features a three-lug bayonet mount with a 44mm throat and a flange to focal plane distance of 46.5mm. The company continues to use variations of the same lens mount specification for its film and digital SLR cameras.

A kit lens is a "starter" lens which can be sold with an interchangeable-lens camera such as a single-lens reflex camera. It is generally an inexpensive lens priced at the lowest end of the manufacturer's range so as to not add much to a camera kit's price. The kit consists of the camera body, the lens, and various accessories usually necessary to get started in SLR photography. 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 SLR kit is often marketed as an upgrade lens for a consumer SLR. In addition, retailers often have promotions of standalone low-end SLR bodies without the lens, or a package that bundles the SLR body with one or two more expensive lenses.
The D40 is a now-discontinued Nikon F-mount entry-level digital SLR, announced November 16, 2006. Compared to its predecessor, the D50, the D40 had several features removed, a few added, and a lower price: US$499.95 ESP as of November 2009 with the 18–55 mm G-II kit lens, positioning it as an entry-level model compared to the D80. The D40x has a 10-megapixel maximum resolution, up from 6 megapixels of the D40 and D50.
