This gallery gives a good idea of the sort of results typical from the D70s/AF-S 18-70mm f3.5-4.5 ED DX combination. A variety of focal length, aperture, and lighting condition results are shown. A 67mm Nikon NC filter is fitted to the lens.
Camera setttings for these shots:
Exposure Mode: Program Auto
Metering Mode: Multi-pattern
File Settings: Large (3008 x 2000) RAW
Optimize image settings:
Tone comp.: Auto
Color mode: IIIa (sRGB)
Hue adjustment: 0
WB: Auto -3
EV: + 0.3
Apart from resizing and saving to .jpg (via. Nikon View 6.2.7), no additional post processing has been carried out, these images are straight off the camera.
Based on my sample I have no hesitation in recommending this lens.
