Rent NowViltrox AF 15mm f/1.7 Air E Lens for Sony E-Mount
Ultra-Bright APS-C Wide-Angle Prime Hyper-Lightweight Architecture & Silent STM Autofocus
The Viltrox AF 15mm f/1.7 Air E is an ultra-compact, featherweight wide-angle prime lens engineered specifically for Sony E-mount APS-C mirrorless cameras. Delivering a versatile 35mm-equivalent focal length of 22.5mm, this “Air” series optic strikes the ideal balance between a high-speed f/1.7 aperture and a travel-friendly footprint. It serves as a perfect daily companion for street photography, sweeping landscapes, architectural documentation, and low-light vlogging where a wide, natural field of view is required.
Despite weighing a minuscule 6.3 ounces, the lens features a highly sophisticated optical formula consisting of 12 elements in 10 groups. This layout integrates three Extra-Low Dispersion (ED) elements, three High Refractive Index (HR) elements, and two aspherical lenses to aggressively suppress geometric distortion, color fringing, and surface reflections. Driven by a swift, near-silent Stepper Motor (STM) for seamless internal autofocus tracking, this lens provides smooth electronic communication with Sony bodies, enabling instant camera-driven aperture adjustments and full EXIF data logging.
This lens is in full operational condition. The package comes ready for field production and includes the original matching lens hood.
Key Features & Optical Performance
Vibrant f/1.7 Low-Light Speed: The exceptionally bright f/1.7 maximum aperture maximizes light gathering for cleaner, lower-noise exposures in dimly lit environments, while providing excellent depth-of-field separation.
Advanced Extra-Low Dispersion Matrix: Built with three ED elements and three HR glass elements to significantly reduce chromatic aberrations and maintain crisp, high-contrast imagery from the center of the frame to the outer corners.
Quiet STM Internal Focusing Engine: Outfitted with a high-performance stepping motor (STM) that delivers rapid, whisper-quiet, and smooth autofocus response times—making it highly optimized for both critical eye-tracking stills and silent video tracking.
Cinematic 9-Blade Circular Diaphragm: Incorporates a rounded 9-blade aperture iris to render smooth, circular out-of-focus highlights and creamy, organic background bokeh.
9.1-Inch Close-Up Focus Performance: Features a short minimum focusing distance of just 9.1 inches (23 cm), enabling dynamic wide-angle macro perspectives with exaggerated foreground subjects.
USB-C Firmware Interface Support: Features a built-in USB Type-C port directly on the lens assembly to facilitate rapid, standalone firmware updates to ensure ongoing compatibility with future Sony camera bodies.
Structural Design & Hardware Inventory
Hardened Aluminum-Alloy Bayonet: The mounting junction is meticulously crafted from a precision hardened aluminum alloy, offering a highly durable, wear-resistant connection to the camera body while maintaining an ultra-light physical profile.
Universal 58mm Filter Interface: Equipped with a standard 58mm front filter thread that accommodates a wide array of screw-on circular polarizers, ND filters, and standard lens accessories.
