Harnessing spherical aberration with its built-in control ring, the Voigtlander Portrait Heliar 75mm f/1.8 Aspherical Lens is designed to maximize photographic creativity when used with full-frame Canon RF-mount cameras. The medium-telephoto prime has a fast, nine-blade iris with a versatile f/1.8 to f/11 aperture range, a 2.3' minimum focus distance, and Canon RF electronic contacts for the transmission of Exif data to a connected camera.
Used in conjunction with its aperture ring, the aberration control ring adjusts for spherical aberration, affecting the image's overall sharpness and allowing a wide variety of bokeh expressions. When set to overcorrect, the lens produces an image with a sharp center of focus and bokeh with a distinct, bubbly shape. When set to under-correct, the center of focus is softer and has slight flairs at the highlights, while bokeh is rendered more gently. To maintain focus position during shifting aberration, the Portrait Heliar 75mm has a built-in mechanism that cancels out misalignment by changing the distance between the three lens groups in tandem with the aberration control ring.
- Manual control ring for adjusting spherical aberration to desired level
- Under-correct to create softer, dream-like images with more aberration and smoother bokeh
- Overcorrect to produce sharper images with precise focus and well-defined bokeh
- Large f/1.8 maximum aperture for shallow depth of field and low-light performance
- Heliar-type optical construction with six lens elements in three groups
- Diamond-pattern manual focus grip with high-precision metal helicoid for ultrasmooth operation
- For use with full-frame Canon RF-mount cameras
- Electronic Canon RF contacts for Exif lens data transmission
- 62mm front thread for filter attachment
