The Lomography New Petzval 85 Art Lens is a stunning reinvention of the legendary Petzval Lens, which was first conceived in Vienna in 1840. This lens was only used ONCE and is compatible with all Nikon F mount analogue and digital cameras. It's in MINT condition and offers photographers and filmmakers the chance to shoot truly unique photographs and videos. Characteristic photos shot with the Petzval 85 are recognizable for their sharpness and crispness in the center, strong color saturation, wonderful swirly bokeh effect, artful vignettes, and narrow depth of field. Because of the characteristic swirly bokeh effect that it produces, the lens is perfect for portraits where you want your subject to be the center of attention. It features premium glass optics and is manufactured in Russia by Zenit, a company with a long and distinguished history in lens design. Specifications: Focal Length: 85mm.
