Nikon's early premium DX kit zoom with faster aperture and professional-grade build.
The Nikon AF-S DX Nikkor 18-70mm f/3.5-4.5G IF-ED was introduced in 2003 as Nikon's higher-specification standard kit zoom for DX DSLRs, bundled with the D70. The 27-105mm equivalent range extended slightly beyond the standard 55mm end of cheaper kit zooms, and the variable aperture of f/3.5-4.5 was faster than the f/3.5-5.6 of the more basic 18-55mm. The inclusion of AF-S Silent Wave Motor and an ED element positioned it as a step above the entry-level kit lens of the era.
The optical design uses 11 elements in 8 groups, including three aspherical elements and one ED element. The 67mm filter thread is larger than the 52mm of the 18-55mm kit lens — photographers pairing the two will need a step-up ring or separate filter sets. At approximately 390g the lens is heavier than the 18-55mm but manageable for all-day carry on entry DX bodies. A minimum focus distance of 0.38m enables close subject framing across the range. The AF-S Silent Wave Motor enables quiet autofocus independent of the camera body's AF drive, ensuring compatibility with D40 and D40x. There is no Vibration Reduction.
For everyday photography the 18-70mm covers the standard range adequately with slightly better aperture at the long end than the basic 18-55mm — f/4.5 versus f/5.6 at the 70mm end is a modest but real difference for indoor and low-light work. The AF-S motor enables compatibility with the widest range of Nikon DSLRs, including entry bodies without a body-side AF motor. Optical quality is good at mid-apertures in the centre across the range. The 67mm filter thread requires a dedicated filter set.
On the used market the 18-70mm is widely available at low prices, now largely superseded by the 18-105mm VR and 18-140mm VR as the preferred mid-range DX kit lens. Condition checks: AF motor response, zoom ring smoothness, and front element for cleaning marks. The 67mm filter thread is shared with the Nikon 18-105mm VR and 18-140mm VR, enabling filter carry-over within a DX zoom kit. Compatible with all Nikon F-mount DSLR bodies including D40 and D40x.
