The Zeiss 18mm f/3.5 Distagon on the 36-megapixel Nikon D800E shows some mild color fringing (lateral chromatic aberration) which is easily correctable with a single checkbox in Adobe Camera RAW, and in certain other RAW converters.
This examples shows the results with and without correction of color fringing.
Points of note in general.
- Color fringing is more noticeable the higher the resolution; the 36-megapixel Nikon D800E is very demanding in this regard.
- With a properly assembled lens, there can be no lateral chromatic aberration (LCA) in the center, and when LCA is present, it will increase away from the center, towards the edges and corner.
- LCA is often hidden with some subject matter, but shows up clearly on high contrast edges as an out-of-register effect.
- Slightly out of focus introduces other additional types of chromatic aberration which are not necessarily correctable; such errors can be additive
