Viltrox AF 9mm f/2.8 Air Lens for Fujifilm X Mount In More Detail
Ultra-wide field of view
A 9mm focal length on APS-C covers113.8º diagonally. This allows large scenes to be captured with ease, which is useful for interiors, architecture and landscapes. It also supports environmental compositions where both the subject and surroundings need to be sharp within a single frame.
Optical construction and image quality
The lens has 13 elements arranged in 11 groups, including 2 aspherical, 3 ED and 3 high refractive elements. This reduces chromatic aberration and maintains detail across the frame, particularly towards the edges where ultra-wide lenses are sometimes soft. Distortion is controlled to keep straight lines straight, which is ideal for buildings and interiors that have to look realistic without converging lines.
Close minimum focusing
A minimum focusing distance of 0.13 metres allows subjects to be placed very close to the front element while retaining a wide background. This creates depth and scale, and also supports focus stacking where multiple images are combined for extended depth of field.
Fast and quiet Autofocus
An STM stepping motor provides fast and quiet autofocus, with face and eye detection available on compatible Fujifilm camera bodies. Focus transitions are smooth with minimal focus breathing, which maintains consistent framing during video focus pulls.
Handling and design
At approximately 175g the lens is compact and lightweight, in keeping with the Air series. A metal mount improves durability, while sealing provides a degree of protection against the environment. The front element includes a coating to resist water and dirt, while the compact 58mm filter thread allows use of circular filters.
Simple firmware updates
A built-in USB-C port allows firmware updates without a separate dock.
