  To measure resolving power we photographed the standard ISO 12233 test chart with each camera set to its best quality JPEG settings. We then set the bundled lenses to f8 using Aperture Priority mode. The crops are taken from the originals and presented here at 100%. Each number represents 100 lines per picture height (lpph), so a figure of 18 means a resolution of 1800 lpph.

The image left was taken with the Canon EOS-350D using the 18-55mm EF-S at 35mm f8; the original JPEG measured 2.48MB. With 1750 lpph of horizontal and vertical resolution, the 350D comfortably beats its rivals.

To measure electronic noise levels we photographed the standard Gretag Macbeth ColorChecker at each of the camera’s ISO settings. The crops are taken from the originals and presented here at 100%. To compare typical noise in skies and dark shadows the crops were taken from patches 3 and 24 respectively.

Canon EOS-350D at 100 ISO

Canon’s EOS-350D clearly delivers the lowest overall noise levels of the group, with 400 and even 800 ISO images being very clean. Nikon’s D50 also performs well on the sky simulation, but reveals higher noise on the black patches.

To measure corner sharpness we photographed the standard ISO 12233 test chart with each camera set to its best quality JPEG settings. We used the bundled lenses at their widest and longest focal lengths with various apertures in Aperture Priority mode. The crops are taken from the lower left corner of the chart and presented here at 100%.

Canon EOS-350D at 18mm f3.5

The 18-55mm EF-S at 18mm f3.5 is slightly soft, but sharper than its rivals, and acceptable once closed by a few stops. At 55mm the lens performs similarly to the competition, although again the best results are when closed by two or more stops.

To measure purple fringing caused by lens chromatic aberrations and sensor blooming, we photographed a custom test chart, left, with areas of very high contrast. We used the bundled lenses at their widest and longest focal lengths with the aperture wide open in Aperture Priority mode. The crops are taken from the upper left corner of the chart and presented here at 100%.

The 350D with the 18-55mm EF-S lens exhibits purple fringing at its widest position, but no worse than its rivals. Fringing is virtually absent at the 55mm end, again in line with the competition.

Canon EOS-350D / Digital Rebel XT macro comparison

Canon 350D / Rebel XT macro test   To measure macro performance we photographed a custom chart using the bundled lenses at a distance and focal length which delivered the maximum possible reproduction. The dark lines are 10mm apart.

The image left was taken with the Canon EOS-350D and the 18-55mm EF-S lens at f8. Like other budget digital SLR lenses, the best macro performance was achieved using its longest focal length of 55mm. Here the lens captured an area measuring 66x44mm from a distance of 13cm. This is essentially the same as the competition, although superior to Konica Minolta.

  To measure geometric distortion we photographed a custom test chart consisting of a grid pattern with perfectly straight lines. Here are the results for the bundled lenses at their widest focal length using an aperture of f8 in Aperture Priority mode. The images were analysed with Imatest using 5th Order line calculation and the full areas presented here at a reduced resolution.

The image left was taken with the Canon EOS-350D and the 18-55mm EF-S at 18mm f8. Barrel distortion was measured at 3.35% which is slightly better than the Nikon and Konica Minolta bundled lenses, but not as good as the Pentax.

  To measure lens vignetting and light fall-off we photographed a white target with a highly diffused custom filter. Here are the results for the bundled lenses at their widest focal lengths with the apertures wide open in Aperture Priority mode. The images were analysed with Imatest and the full areas presented here at a reduced resolution.

The image left was taken with the Canon EOS-350D and the 18-55mm EF-S at 18mm f3.5. The light falls off to an average of 68.8% in the corners, which while better than the Pentax, is well below the Nikon and Konica Minolta results.
