Paying homage to the classic designs of some of Voigtlander's earliest lenses, the Heliar 50mm f/3.5 is a unique normal-length prime intended to provide a vintage image quality, complete with rich color saturation and high sharpness. Compatible with 35mm film and full-frame M-mount rangefinder cameras, this lens uses a traditional Heliar optical design and features a durable all-metal exterior with an engraving of the five-elements-in-three-groups optical layout. Smooth manual focus operation permits working with subjects as close as 2.3' away, and a de-clicked manual aperture ring permits making smooth, silent aperture transitions to benefit both stills and video applications. Additionally, a 10-blade diaphragm is featured to contribute to a smooth bokeh quality.
