Canon EF 55-200 mm f/4.5-5.6 II USM

5. Chromatic aberration

At the focal length range ends chromatic aberration is visible at the 0.10% level. At 55 mm the aberration increases slightly when the diaphragm value increases. At 200 mm the situation is the exact opposite.

The chromatic aberration completely disappears at the 100 mm focal length, which is a very interesting characteristic for the Canon 55-200. When using a diaphragm, the aberration is at a 0.02% level. It is thanks to this feature that the picture resolution at the edges of the frame at 100 mm is so good.

In the pictures below we present the ISO table 1:1 clippings set up 70% away from the center of the field of view. We can clearly see the high chromatic aberration at 55 and 200 mm and its absence at 100 mm.
