I have a cuple of soft focus lenses which are new to me and this is some of the early results. Both were created with camera on a tripod. I'll probably closing the Petzvar down a bit on my next attempt. That is not possible on the Portragon.
Great boka. Is a Petzvar like a Petzval? Lomography sells Petzvals with similar boka. As for the photo, I like the lighting and the way you caught the slight smile.
Bruce- the Lomography Petzval is not in fact a Petzval, but a re-bodying of an FSU 85mm Helios lens. It swirls, but it's not the same as a real Petzval in that the swirl can be avoided even when shooting wide open, depending on the placement of subject relative to background.
