Viltrox has formally announced the release of its AF 16mm F1.8 Z lens, a fast, wide autofocus prime lens for full-frame Z-mount cameras. It joins the lineup next to Viltrox’s existing AF 16mm F1.8 lens for Sony E-mount. Viltrox says the lens is aimed at applications like astrophotography, landscape and architecture.
The AF 16mm F1.8 Z is built around 15 elements in 12 groups, including 4 ED and three aspherical elements. It has a minimum focus distance of 0.27m (11″) and a maximum magnification ratio of 0.1.
A stepper motor drives autofocus. The lens has a nine-bladed aperture.
The lens also includes two function buttons and includes one-click access to infinity focus, a feature that should be popular with astrophotographers. It features a 77mm filter thread. Viltrox describes the lens as “dustproof.”
Although Viltrox is formally announcing the AF 16mm F1.8 Z today, reviews on YouTube began appearing last week.
The AF 16mm F1.8 Z has a suggested retail price of $549 and is available immediately.
