Nice! What's with these lenses? I hear a lot about them on LF forum, but what are the main things that make it a "petzval"? The apperture?
its just the cut and quality of glass and the way the lens is built. Petzval lenses are most notable for their super dreamy swirl bokeh.

most antique brass lenses have the swirl mostly because they are just holes for the aperature opening. but the way the glass is cut and arranged on a petzval creates a more intense swirl and seperation from the back and foreground
