Lens review

Canon EF 100-400 mm f/4.5-5.6 L IS USM
6. Distortion
Geometric deformations at the frame edge won’t disturb us for sure too. The distortion value, measured in our tests at the focal lengths of 100, 200, 300 and 400 mm was respectively: -0.10%, 0.37%, 0.44% and 0.51%. All these values are very low, so rather negligible in real situations. In this category the lens also deserved our praise.
