On Just About Every Performance Consideration This is a Fine Lens

Nikon 18-70mm DX 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.  Mar 9, 2011 ✓

Features

• 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.

• One AS - 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. Nikon’s IF engineering allows that to happen. All internal optical travel is contained within the inside of the non-extension lens container.

• M/A mode
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.
