Voss and Beslar (sp) are the bottom of the barrel lenses. The should be put in vending machines for kids to play with. I don't know much about "bokeh" but I had both when beginning, they came with the enlargers just for shits and giggles I guess, and chucked them immediately for a much better, that wasn't hard, real lens. After the Voss tossing the Beslar went much faster.
