Definition most likely applies to most countries (except certain rogue states):

Hey, you have a "Petzval" alternative !
And it gives the proper "character" on APS-C !
Now find some well dressed ladies and gentlemen to pose formally with their shoulders and ears blurry.

Considering the silly prices petzwals costs these days, I think I can sell these lens too. This particular example has no aperture yet, but I will add it later, I can do either 13 or 16 leaf circular apertures.
