The Lomography Joseph Petzval lenses are distinctive creative lenses inspired by the original 19th-century Petzval optical design, known for their pronounced swirly bokeh, strong center sharpness, and unique vintage character. Featuring a fast aperture and intentionally stylized optical rendering, these lenses create dramatic subject separation and an unmistakable sense of movement and depth. These are E-Mount lenses and have manual focus and iris control as well as a ring that controls the appearance of the bokeh.
