This Sigma EF 18-250mm AF Stabilized lens is a great addition to your Canon EF camera. With a maximum aperture of f/3.5, it allows for great low-light shots. The lens is compatible with Canon cameras and has an autofocus feature. The focal length range is from 18-250mm, making it a versatile lens for various shots. The mount is Sigma, and it is part of the Canon EF series. This zoom lens is perfect for photographers who want to capture sharp and clear images. I m selling this lens because I’ve decided to go to a mirrorless system. It is a very nice “walking around” lens with great versatility.
