Viltrox AF 9mm f/2.8 Air Ultra-Wide APS-C Compatible with Sony E-Mount

Capture ultra-wide landscapes, interiors, and vlogs with F2.8 clarity, edge-to-edge sharpness, and speed.

The Viltrox AF 9mm f/2.8 Air is a compact ultra-wide APS-C lens for Sony E-Mount cameras, delivering unmatched creative freedom in landscapes, architecture, tight interiors, and immersive vlogging. With a 13.5mm full-frame equivalent focal length, it offers a 113.8 ultra-wide field of view, capturing expansive backgrounds and striking foreground detail in every shot. Designed for portability, the lens weighs just 175g, making it ideal for travel and handheld shooting. Its bright F2.8 aperture ensures sharp, clear images in low-light settings while allowing faster shutter speeds and lower ISO for pristine results.

This lens is a well-crafted 13-element, 11-group optical design, including 2 aspherical, 3 ED, and 3 HR elements. This construction minimises chromatic aberration and distortion, maintaining edge-to-edge clarity while rendering straight lines and shapes faithfully.

Fast, precise autofocus is driven by an STM stepping motor, delivering responsive performance for dynamic scenes, street photography, or immersive video. Minimal focus breathing ensures smooth transitions, ideal for focus stacking and cinematic storytelling.

Built to last, the lens has a durable metal mount, sealed body for dust and moisture protection, and a water- and smudge-resistant front element. A standard 58mm filter thread allows creative accessory use, and the USB-C firmware port ensures easy updates to maintain peak performance. With a 0.13 m minimum focusing distance, the AF 9mm f/2.8 Air allows striking close-ups, dramatic foreground compositions, and rich depth for truly immersive imagery.
