Description
The PORTRAIT HELIAR 75mm F1.8 is Voigtländer's first full-frame interchangeable lens with spherical aberration control. It is a large-aperture, manual focus, medium telephoto lens designed exclusively for Sony E-mount mirrorless cameras. The optical design is optimised for Sony’s image sensors and covers the full-frame image circle.
Key Optical Features
- The lens construction follows the classic HELIAR type: 6 elements in 3 groups.
- Wide maximum aperture of F1.8 for creative depth-of-field control.
- Spherical aberration can be adjusted via a dedicated control ring, allowing custom bokeh rendering.
- Under-correction creates soft-focus highlights and gentle rear bokeh.
- Over-correction retains centre sharpness with bubbly after-blur.
- These optical characteristics, traditionally considered flaws, have been intentionally embraced to enable expressive photographic effects.
Spherical Aberration Control
- The control ring adjusts spherical aberration by altering the distance between lens groups.
- A tactile finger point allows users to feel the ring position, aiding intuitive operation.
- As spherical aberration shifts focus, the lens includes a mechanism to compensate for focus misalignment during adjustments.
- Electronic Integration & Stabilisation
- Equipped with electronic contacts for EXIF data transfer (aperture, focal length, etc.).
- Compatible with Sony cameras featuring 5-axis in-body image stabilisation using distance encoder data.
- Focus peaking and magnified viewfinder assist supported via manual focus ring.
- Build & Handling
- Precision-engineered, all-metal barrel with a diamond-patterned focus ring for excellent grip.
- Silky, dampened manual focusing thanks to a high-precision metal helicoid.
- Aperture control is manual, with a 9-blade diaphragm that produces pleasing bokeh from point light sources.
- Minimum focusing distance: 0.7 m.
Main Features
- Adjustable spherical aberration control ring for varied bokeh effects
- Sony E-mount electronic contacts for metadata and stabilisation
