Hello and right away a question
#7
"LoCA and "bokeh fringing" are the same, aren't they? How are they not identical?"

 

A while ago I had a chat with a physicist. He said that LoCAs are somewhat different from bokeh fringing.

When looking at our usual test target, the fringing is primarily visible in the blur portions. 

However, just like lateral CAs, axial CAs are actually located at the focus point not beyond.

While he agreed that there seems to be a certain dependency, the "bokeh fringing" has at least an additional cause.

He wasn't too sure about it either though.
