Nikon D40 with AF-S Nikkor 18-55mm 1:3.5-5.6 G II ED Gordon Laing, March 2007

Nikon D40 purple fringing comparison

  To measure and compare the Nikon D40's purple fringing caused by lens chromatic aberrations and sensor blooming, we photographed a test chart with areas of very high contrast using it and a number of rival models.

We used the kit lenses at their widest and longest focal lengths with the apertures wide open. The crops are taken from the upper left corner of the chart and presented here at 100%.

Like the other kits tested here, the D40 and its DX 18-55mm II kit lens exhibit coloured fringing at wide angle, but comparatively little when zoomed-into telephoto.

Nikon D40 macro comparison

Nikon D40 macro test  

To measure and compare the Nikon D40's kit lens macro performance we photographed a custom chart using it and a number of rival models.

Each camera was positioned at a distance and set to a focal length which delivered the maximum possible reproduction.

The dark lines are 10mm apart and the result is not cropped. Smaller areas are preferred in this test. The image left was taken with the Nikon D40 using the DX 18-55mm II kit lens.

DX 18-55mm II at 55mm f8
Max area of 74x48mm

Like most DSLR lenses, the greatest macro reproduction was achieved with the lens zoomed-in to telephoto. There the Nikon D40 and DX 18-55mm II captured an area measuring 74x48mm.

This is fractionally bettered by the Canon and Olympus kit lens, but all are comfortably beaten by the macro capabilities of the PowerShot G7. Closest focusing distance is an advantage almost all compacts have over DSLRs, unless the latter are equipped with specialist macro lenses.
