This is the lens that started my love affair with Lensbaby. I always was a rule breaker, always did my own thing, and always strived to push my artwork to a whole new level. I needed a lens that would complement a conceptual portrait I had in mind, and knew the background had to be something besides the usual out of focus bokeh. I always obsessed over the hypnotic quality of Petzval's swirly bokeh, but the cost was out of my budget. Thank goodness I stumbled across the Twist 60, that has an uncanny resemblence to this legendary Petzval glass.
