On Just About Every Performance Consideration This is a Fine Lens
This lens was announced at the same time as the
Nikon D70 digital camera. Although the 18-70mm is not a cut rate kit lens while it
encompasses a very desirable focal length range of 27-105mm equivalent to 35mm film format. On just about every performance consideration this is a fine lens. a single exception is the vignetting. Additionally, It features Nikon's favorably regarded technologies that Nikon lens users expect, with features like a distance information window guide, a sturdy metal lens mount providing years of robustness, plus a M/A mode switch for seamless swapping from
autofocus to manual mode.
The 18-70 was the very first midrange Nikon zoom engineered for shorter focal lengths
necessitated by digital cameras. First announced at the same time as the D70 in 2004. I really liked this midrange zoom on digital until the and lens expensive and improved 18-55 lens was introduced in 2005. Subsequently the 18-200 with VR became available at the end of 2005 which became a couple of selections in front of the 18-70mm, providing you can substantiate the price difference.
Designed to be used with
DX Format DSLR only, DX Nikkor lenses provide a flexible reach for
angle-of-view, better performance, and superb middle to corner to edge image performance, while at the same time providing smaller and lighter lenses.
Every Nikon DX lens has a picture angle similar to a 35mm film format lens
multiplied by a factor of 1.5.
Things to dislike The hood that's included has a really cheap feel. In poor light situations, the aperture opening is limited, for improved photography indoors you need a fixed f/1.8 or a zoom f/2.8 lens, although, they can cost 3 times as much, or better yet get a prime f/1.8 lens and forget zoom altogether.

AF-S Autofocus lens featuring a Silent wave, coreless, integrated, focus motor (unwrapped in 1996). Basically an updated AF-I Autofocus-Silent sporting a "Silent Wave Motor" (ultrasonic)
to focus near silently and fast.
Aspherical lens elements
- Nikon unveiled the first lens in 1968 featuring aspherical camera lens elements. What makes them different? Aspherical lenses all but eliminates the issues of coma and related kinds of lens aberrations
even when employed at the maximum aperture.
D- Distance. Denoted after the f-number.
It signifies the lens has the capacity to use
Nikon's 3D Matrix Metering
on camera bodies where it is supported.
DX - NIKKOR - Compact and lightweight
Nikon DX lenses feature a lesser image circle and are specifically created and
optimized for the Nikon D-series, digital SLR camera bodies. An ideal option for
photographers and enthusiasts who require shooting of expansive landscapes with
Nikon DX DSLR
Three ED- (Extra-low Dispersion Glass)
a necessary element of the Nikon telephoto lens
Nikon engineered Extra-low Dispersion optical glass to facilitate the
manufacture of lenses that provide superior color correction and sharpness by
diminishing chromatic aberrations
G - labeled after the f-number.
A G-lens contains no aperture ring, therefore aperture may only be
electronically controlled by the camera and only autofocus camera bodies
featuring function dials have the capacity to control G lenses
IF- Internal Focusing
The ability to have a lens focus while it's size remains unchanged. Nikons
IF engineering allows that to happen. All internal optical travel is contained
within the inside of the non-extension lens container.
AF-S Nikon lenses include the exclusive Nikon M/A focus function, that permits
switching from auto to manual focus virtually without time lag - even while the
AF servo is in operation regardless of the AF mode in play.
RD- Rounded 7 Blade Diaphragm
Soft-focus images of point light resources create accepted polygonal shapes that
mirror the form of the cavity produced by the diaphragm blades.
SIC - Nikon Super Integrated Coating
Nikon uses an elite multilayer lens coating to augment the operation of its
lens elements which also helps diminish ghosting and flare to minute levels.
Nikon Super Integrated Coat also accomplishes several purposes,
SWM- Silent Wave Motor
Nikon AF-S engineering is yet one more rationale why professional photographers like Nikon telephoto optical lenses.
