Lomography went old-school a couple of years ago, reviving the classic Petzval lens for Canon and Nikon DSLRs, and now they’re going to the 19th century well once again. Check out the Lomography Petzval 58 Bokeh Control Art lens.
Billed as “the world’s first Petzval bokeh control lens,” this 58mm f/1.9 lens features a “Bokeh Control Ring” that lets you adjust the strength of the swirly bokeh effect in your photos. There’s plenty of color saturation, artful vignetting, and yes, swirly bokeh. For the unfamiliar, bokeh is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Made by hand using “premium Russian glass optics,” the lens has been specially developed to work with modern analogue and digital cameras and is available in Canon EF and Nikon F mounts. [Purchase]
