Introduction | Canon EF 28mm f2.8 IS USM lens performance | Canon EF 28mm f2.8 IS USM versus competition | Conclusion
Canon EF 28mm f2.8 IS USM

With a DxOMark score of 26 the Canon 28mm ranks very high. It is the second best of all wide Canon lenses and, if you include independently made lenses, it still ranks 5th out of all canon fit wide lenses. The scores for P-MPix are even better, showing that this is a nice sharp optic, scoring 15P-MPix. If you narrow the field further and look for just 28mm lenses, this one is the top scorer.

The individual test results show a lens that is very consistent, the only place where the scores dip is when used with a small aperture when the resolution does fall off. Chromatic aberration is well controlled, distortion is not excessive transmission is excellent and vignetting, while noticeable when using the lens wide open is exactly what you would expect of a 28mm lens.

Wide open the EF 28mm f2.8 vignettes by nearly 2 stops, this disappears rapidly as the lens is stopped down. Criticizing the lens for this is rather harsh since the same results appear for nearly all lenses in this category
