Optical character
The L-Mount version of Viltrox's budget 20mm is a 159g, 52.3mm-long wide-angle that takes 52mm filters, a natural match for small bodies such as the Lumix S9. Viltrox pitches it at travel, street, interiors and vlogging.
Ten elements in eight groups include two ED, one high-refractive-index and two aspherical elements. A lead-screw STM motor drives internal focusing down to 0.19m (0.17x), and the front element has a water- and dust-resistant coating. There is no aperture ring or switch; the barrel has a focus ring, a metal mount and a USB-C port for firmware, and native L-Mount support lets the camera apply lens corrections.
