SIGMA 70-300mm f/4-5.6 zoom lens, offering a wide range of focal lengths, suitable for everything from landscapes to portraits. The exterior is very clean, and it takes great photos^_^ Autofocus sometimes works and sometimes doesn't, but it usually fixes itself by turning the power off and on again. There are small black spots in videos, but I don't think they're noticeable. - Brand: SIGMA - Model: 70-300mm f/4-5.6 - Focal Length: 70-300mm - Aperture: f/4-5.6 - Condition: Good Thank you for looking.
