Nikon AF-S 18-70mm f3.5-4.5G ED  DX

Test Results

Sharpness in the center of the frame at all focal lengths is very good to excellent and stopped down it gets even better. However it’s not perfect - There is a lot of distortion at the wide end of the range. If you look at the test pictures you’ll see that at 18mm the houses change size and shape when they’re placed in the corner of the frame.
