Lensbaby's Twist 60 is all about the bokeh. It promises appealing subject/background separation with Petzval-like swirly bokeh, offering an F2.5 maximum aperture. The Twist 60 is part of Lensbaby's Optic Swap system and is currently offered for Canon, Nikon and Sony E mounts. We just couldn't resist taking it out for a spin  — and we have to confess that we stuck mostly to wide open apertures in order to get the full swirly effect.  Take a look at our samples below, and stay tuned for more thoughts on swirly bokeh!
