Then again I'm no optics expert.

Nor am I. Jason is much better informed on these details than I am. If the Verito is a petzval, then there is something different about it to add the beautiful diffusion that it gives at and near wide open. The Derogy and the Dallmeyer that I have are petzval lenses but exhibit NO diffusion or soft focus effects wide open or stopped down.
