SEL50F18F This is a single-focal-length lens for Sony full-frame cameras. I purchased it in September 2023 and used it only indoors for children's events. I haven't used it many times since I bought it, and I've always stored it in a dry cabinet. I'm selling this lens because I bought another one. In my amateur opinion, there is no dust, dirt, or mold inside the lens, and the exterior is in very good condition with no noticeable scratches. I'm selling it as a set with the lens hood, box, and CPL filter. This is a 50mm F1.8 lens compatible with E-mount, allowing for high-quality shooting with a bright aperture. - Brand: SONY - Model Name: FE 50mm F1.8 - Mount Type: E-mount - Filter Diameter: 49mm - Included Accessories: Lens hood, filter Thank you for looking.
