Canon EF-S 17-55mm f/2.8 IS USM wide-angle geometry comparison

Canon 17-55mm wide angle geometry test
17-55mm EF-S at 17mm f8
Distortion: 2.87% barrel

The lenses were tested at their widest focal lengths with an aperture of f8 in Aperture Priority mode.To measure and compare the Canon 17-55mm’s geometric distortion we photographed a test chart consisting of a grid pattern, using it and a number of rival lenses.

The images were analysed with Imatest using 5th Order line calculation and the full areas presented here at a reduced resolution.

The image above was taken with the Canon EF-S 17-55mm at 17mm f8. Barrel distortion was measured at 2.87% which is well below the other EF-S lenses on test and roughly the same as the EF 17-40mm L – this is impressive considering the latter is designed for a full-frame body, so should perform impeccably on an EF-S body.

17-55mm EF-S at 55mm f8
Distortion: 1.09% pincushion

The lenses were tested at their longest focal lengths with an aperture of f8 in Aperture Priority mode.To measure and compare the Canon 17-55mm’s geometric distortion we photographed a test chart consisting of a grid pattern, using it and a number of rival lenses.

The images were analysed with Imatest using 5th Order line calculation and the full areas presented here at a reduced resolution.

The image above was taken with the Canon EF-S 17-55mm at 55mm f8. Pincushion distortion was measured at 1.09% which is roughly similar to the EF-S 17-85mm lens, albeit not as good as the budget EF-S 18-55mm, nor, unsurprisingly, the EF 17-40mm.
