Utilizing a classic optical design to produce a distinctly contemporary image quality, this brass Petzval 58mm f/1.9 Bokeh Control Art Lens is characterized by its immensely swirly bokeh, strong field curvature, and sharp central focus. Designed for Canon EF-mount cameras, this lens simulates the look of the first Petzval lens from 1840, yet updated for use with current 35mm film and DSLR cameras. Emphasizing the swirly bokeh quality of this lens design, this 58mm version incorporates a unique Bokeh Control Ring on-top of the lens to adjust the bokeh intensity within a 1-7 Level range. Russian glass is used to deliver a high degree of sharpness and color accuracy and a simple, manual geared rack focus system permits working with subjects as close as 2' away. Aperture settings are controlled using seven different Waterhouse stops, ranging from f/1.9 to f/16, and the bright f/1.9 maximum aperture is especially well-suited to shallow depth of field effects and working in low-light conditions. A special effects lens well-suited to portraiture and artistic imagery, Lomo's second Petzval lens increases the amount of control over bokeh while retaining the celebrated classic look.
