Overview: This 0.4x wide-angle conversion lens screws onto the front of your existing lens to broaden its field of view, turning your regular lens into a super-wide option for both photo and video work. Mounting: Confirm your lens thread diameter before purchasing — it must be one of these sizes: 49, 52, 55, 58, 62 or 67mm. The thread size is usually stamped on the lens barrel, printed on the glass, or shown under the lens cap and is always preceded by a diameter symbol (see product images for guidance). Optical construction: Built with all-glass, multi-coated elements, the lens delivers clear, sharp images with a sleek black exterior. Key optical performance figures include just 1% distortion and 2.3% vignetting, helping preserve image quality across the frame. Performance: Designed for fast, reliable operation, the attachment supports extreme-speed auto focus and smooth handling for wide panoramic shots with minimal artifacts. Filters and compatibility: The unit accepts 82mm filters. Included in the box: Lens, lens pouch, lens caps, adapter rings (49, 52, 58 & 67mm), and warranty. Origin & warranty: Manufactured in Japan and covered by a 5-year USA manufacturer’s warranty.
