Hey, Pavlov's Dogs -
Just because something is a "Sonnar-type" doesn't mean that it is good.
- Sonnars were a workaround for a lack of coatings in the day. That they disappeared with the advent of modern coatings should tell you something.
- Sonnars are normal- to long-length lenses, and there is a reason that modern wideangle lenses use highly corrected aspherical, retrofocal, and/or symmetric designs. The shortest mainstream "Sonnar," as I recall, is the 40mm for the Tenax.
- Sonnars have some appeal for people pictures not because they are good but because within certain parameters, they are bad. The the shorter they get the more distortion they have.
- Sonnars (real ones) don't have great bokeh unless they are seriously uncorrected like the ZM.
By the way, this actually looks more like a design, ahem, homage to the UC Hexanon.
Is it interesting? Yes. Is it compelling? Who knows. The sample pics were nothing to Internet home about.
