Lateral Chromatic Aberration: Nikon 24mm f/1.4G

Today I was processing some product shot images (biking) that I had shot with the Nikon 24mm f/1.4G. Right away, I noticed the red/cyan color fringing with the Nikon 24mm f/1.4G, something all but absent from the new Zeiss 25mm f/2 Distagon, though even it can show faint color errors in some situations.

(I was shooting the Nikon lens because I was in a rush with rain about to ruin my setup, the Nikon 24/1.4G was already on the camera, and autofocus is fast and handy— and I have no Zeiss 25/2 for Nikon as yet.)

While this color fringing (lateral chromatic aberration) is actually very low as such things go, I find that it immediately grabbed my attention in this particular series, and I felt that I could not display the images with such a defect. In some shots, the entire wheel/tire interface showed a circular red line!

Fortunately, the lens correction feature in Adobe Camera RAW can correct this color fringing. As a bonus, distortion can also be corrected, worthwhile for a shape such as a wheel.

The JPEG compression used here reduces the appearance of the fringing, and seeing more at once makes it more visible, so my comments are based on the original TIF.

Mouse over the left crop to see it change to the corrected version, also shown at right.
