The AF-S DX Zoom-Nikkor 18-70mm f/3.5–4.5G ED-IF is an F-mountzoom lens manufactured and sold by Nikon. Designed exclusively for use on Nikon DX format cameras, this lens covers from wide-angle to medium-telephoto range.
This lens was announced in January 2004 [2] and was initially available as kit lens for the then-new Nikon D70. Later, it was possible to acquire separately and as a kit with other Nikon cameras.
Lens construction includes one composite aspherical and three Extra-low Dispersion (ED) elements to correct distortion and aberrations. This helps overall lens performance, which is rated excellent on most respects except light falloff.[3]
This lens has been largely supplanted by those lenses which have since been supplied as the kit lenses for the Nikon prosumer cameras; first the 18-135mm AF-S which shipped with the Nikon D80 and later the 18-105mm AF-S VR which ships with the Nikon D90.
