The Viltrox AF 16mm F1.8 is an ultra-wide prime pairing a bright f/1.8 aperture with a 105.6Β° viewing angle. The review lists a 15-element, 12-group optical formula including three asphericals and four ED elements, HD Nano multilayer coatings and a fluorine front element. The lens measures 85x103mm, weighs about 550g, and includes a 77mm filter thread and supplied petal hood. Controls include an aperture ring with click/de-click, AF/MF switch, two function buttons and a colour LCD info screen. Autofocus uses a linear stepping motor described as fast, smooth and virtually silent. Image quality is strong with impressive edge-to-edge sharpness wide open, with expected vignetting at the widest apertures.
