Pure yellow to show/determine LoCA is maybe not ideal... Especially since some lenses have blue/yellow LoCA! Better to just use black print on white... I do detect a different colour behind focus than in front of focus, but impossible to judge with this yellow.
Big lens, looks like IF is a drawback concerning mirrorless and compactness, where macro lenses are concerned.
High CA for a macro lens, but looks like the background bokeh is nice and smooth (foreground bokeh not so much, unsurprisingly of course).

I have never seen yellow bokeh fringing.
However, yes, the target is not ideal.
