5. Chromatic and spherical aberration

Chromatic aberration

Photos below prove well that the Panasonic Leica DG Elmarit 200 mm f/2.8 POWER O.I.S. doesn’t have any problems with longitudinal chromatic aberration. Even at the maximum relative aperture and in blurry area positioned further on it would be difficult to notice any colouring. This statement remains true for both the lens and the lens plus the converter set.

The results of the lens itself range from 0.03 to 0.04%; it means this aberration level is very low. After attaching the teleconverter the values increase to almost 0.06% but they still can be called low. Overall, when it comes to lateral chromatic aberration the tested lens won’t be troublesome at all.

Spherical aberration

The tested lens didn’t have any „focus shift” effect and circles we created in front of and behind the focus were beyond reproach. Adding to that its sensational image quality by f/2.8 we can state the tested Panasonic has no problems whatsoever with spherical aberration. The same is true when it comes to the lens plus the teleconverter combination.
