Canon EF 90-300 mm f/4.5-5.6 USM

5. Chromatic aberration

The chromatic aberration does not bother us at all at the 90 to 135 mm focal length. At most of the diaphragms it is at a minimal level. The defect increases to average level at 200 mm and bursts out at 300 mm. At the maximum focal length, and diaphragm at f/8 and above, the aberration is, unfortunately, at a high level. Only at maximum aperture is the defect level close to average.

The Canon’s 90-300 mm performance is a bit weaker than the Sigma and the Canon 100-300 mm, which at smaller focal lengths had a lower aberration level, but at 300 mm didn’t burst out as the 90-300 mm model did. The Tamron didn’t burst out with its aberration either but this lens’s aberration at the lower focal lengths is a bit larger than the Canon EF 90-300 mm.
