My 85mm F/1.8 exhibits excessive color fringing on high contrast transitions which are out of focus. (Longitudinal Chromatic Aberration) Edges behind the focus point show green while those in front show reddish tones. This detracts from its bokeh. This problem is not obvious in lower contrast scenes, but some of my real-life photos show this problem.

Switch to "Original" size to best see the fringing.
