Chromatic aberration

The Panasonic Leica DG Vario-Elmar 100–400 mm f/4.0–6.3 ASPH. POWER O.I.S. doesn’t have any problems related to the longitudinal chromatic aberration. Photos shown below were taken at 300 and 400 mm and it is clear that the cast of images situated outside the focus plane is slight and won’t spoil your photos.

The optics constructors of the Panaleica 100-400 mm also managed to correct the lateral aberration in a good way and the graph below shows it pretty well.

The aberration never exceeds 0.09% and it means that at all combinations of apertures and focal lengths its level is low even if the results differ a bit. In the middle of the focal range the lowest values are seen at the maximum relative aperture and the level of the aberration increases noticeably on stopping down the aperture. At the shortest focal length the situation is reversed – at the 400 mm focal length the aberration depends weakly on the aperture values, keeping all the time near 0.07-0.08%.

Spherical aberration

First photos of this chapter show clearly that the lens doesn’t have any problems with “focus shift”. Circles of light we got in front of and behind the focus seem to be very similar to each other. It all means the Panasonic 100-400 mm doesn’t have any noticeable problems with the correction of spherical aberration.
