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.
a smoothie + a nice portrait lens at 185g .... not sure about the tooth brush though

Would have expected that this lens is a better performer than measured here. The 25mm Pana reaches this level of center resolution already at f/1.4. Anyhow, in use I´m pretty happy with the results even at f/2.8. Let´s see how it compares to the upcoming 60mm f/2.8 Sigma.
Somehow I expected better results; esp with regards to CA (it is pretty much not visible in images but even in the 12-35 review it is quite visible). Also was this sample decentered or is this the norm ? I mean the resolution numbers are lower than the 12-35 zoom and it is a more favorable focal length (easier to make tele than wide angle).

This sample was just fine - no decentering problems!
