This is a SONY single-lens camera lens I purchased about 10 years ago. I have confirmed that it works, and there are no operational issues. <Main Specifications> - Focal Length (mm): 16-50 - Maximum Aperture (F-value): 2.8 - Minimum Aperture (F-value): 22 <Included Accessories> - Lens Hood (ALC-SH117) - Front Cap - Rear Cap - Box - Lens Filter (Kenko C-PL(W)) *This was purchased separately from the lens, but I'll include it as a bonus. *Everything shown in the photos is included. <Scratches/Stains> - There are some minor scratches on the mount. - There is some fine dust inside the lens, but I don't think it will affect the photos.
