5. Chromatic aberration

To be honest I thought that such a slow lens as the Sigma 2.8/30 would’t have any problems with the longitudinal chromatic aberration. Unfortunately I was wrong. What’s more that aberration doesn’t disappear completely even on stopping down the lens to f/4.0. It can be noticed very well looking at the crops below.

In fact the lateral chromatic aberration can be described in similar terms. That aberration seems to be independent of the aperture value and it is situated between medium and high level throughout the whole range.

To sum up when it comes to the correction of both types of chromatic aberration it would be difficult to praise the tested lens here. From a fixed-focal f/2.8 instrument, not very fast after all and significantly bigger than ‘pancakes’, you definitely should expect something more.
