Voigtländer PORTRAIT HELIAR 75mm f/1.8 full-frame lens for Sony E-mount offers a spherical aberration control ring that provides under- or over-corrected spherical aberration for a creative bokeh look. The lens has fully manual focus and aperture control, but the pins provide EXIF data and a manual focus assist. In recent years, we have seen numerous fast manual prime lenses from Voigtländer. One example might be the Voigtländer 50mm f/1.0 Nokton lens from 2022 that covers full-frame sensors. Recently, Cosina (the lens manufacturer producing Voigtländer lenses since 1999) announced a new lens with a unique trick up its sleeve – the Voigtländer PORTRAIT HELIAR 75mm f/1.8. Let’s take a closer look. Voigtländer PORTRAIT HELIAR 75mm f/1.8 lens. Source: Cosina Voigtländer PORTRAIT HELIAR 75mm f/1.8 lens This new full-frame portrait prime lens comes with the Sony E-mount. Although its focus and aperture operation are fully manual, the lens features electronic communication pins for EXIF data transfer. Furthermore, the built-in distance encoder supports 5-axis image stabilization on the body side. Other features, enabled by the active lens-camera communication, include manual focus support (magnifying the finder display by operating the focus ring). The aperture diaphragm comprises 9 blades to make the aperture opening as circular as possible. According to Cosina, point light sources have well-rounded out-of-focus areas. The aperture is available between f/1.8 and f/11. The optical structure of the lens includes 6 elements in 3 groups. Spherical aberration control ring.
