Lens Test – Nikkor 105mm F2 DC vs. Nikkor 80-200mm F2.8 AF – Longitudinal Chromatic Aberration (LoCA)

Nikkor 105mm F2 versus 80-200mm F2.8 Longitudinal Chromatic Aberration Test. How much does the ED glass impact on the chromatic aberration for the zoom lens as opposed to the prime lens? It is difficult to find anywhere any direct tests between lenses of the same focal length. Conditions of the settings on camera are shown in the image captions. Everything else has been fixed. Slight error in the exact focal length for the zoom lens. Camera used is Nikon D810, RAW file capture. Images examined in Adobe Lightroom.

Lenses used:

Nikkor 105 F2 DC

Nikkor 80-200 F 2.8 AF (1988-1992)
