TTArtisan AF 17mm f/1.8 Air Lens (Sony E)

Overview

The TTArtisan AF 17mm f/1.8 Air Lens for Sony E is a compact and lightweight wide-angle prime designed for APS-C mirrorless cameras. Offering a 25.5mm full-frame equivalent focal length, this versatile lens is ideal for street photography, landscapes, architecture, travel, and everyday shooting. Its bright f/1.8 maximum aperture provides excellent low-light performance while also enabling shallow depth of field and smooth background separation for more creative compositions.

Designed with portability and everyday usability in mind, the lens features a durable aluminum body while remaining compact enough for all-day carry. An STM autofocus motor delivers smooth and quiet focusing performance, making the lens suitable for both still photography and video recording. The optical design incorporates two extra-low dispersion elements and three high-refractive index elements to help reduce flare, ghosting, and chromatic aberrations while maintaining strong contrast and sharpness across the frame. A close 18 cm minimum focusing distance further expands creative possibilities for dramatic close-up wide-angle imagery.
