The picture beneath is a a hundred% crop taken from the top-left nook of an a7R III body. In the examples below, look at the fringing colors within the out of focus specular highlights created by the neutrally-coloured topics. A comparatively widespread lens aberration is axial CA, which causes non-coinciding focal planes of the varied wavelengths of light, or extra simply, different colors of light are focused to totally different depths.

This spectacular coma performance can be corroborated by photographer Nate Luebbe, who shows his outcomes from pictures of starry skies with this lens in his video right here.

This lens design incorporates two AA components and three ED (Extra-low Dispersion) glass components as seen under. While not completely round, the corner circles aren’t very distorted.
