Canon EF-S 17-55mm f/2.8 IS USM purple fringing comparison

We tested each lens at its widest and longest focal lengths with the aperture wide open. The crops are taken from the upper left corner of the chart and presented here at 100%.To measure and compare the Canon 17-55mm’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 lenses.

The Canon EF-S 17-55mm exhibits a little purple fringing at its widest position in line with the others. Fringing is virtually absent at the long end, again in line with the other three.

17-55mm EF-S at 55mm f8
Max area of 124x82mm

The dark lines are 10mm apart and the result is not cropped. Smaller areas are preferred in this test.To measure and compare the Canon 17-55mm’s macro performance we photographed a chart using it and a number of rival lenses at a focal length and distance which delivered the maximum possible reproduction.

The image left was taken with the Canon 17-55mm zoomed-into 55mm where it captured an area measuring 124x82mm. This is a larger area than the other three lenses on test, and proves there’s better choices if macro’s your thing.
