High-quality 24-105mm zoom lens with image stabilization. - Model Name: EF 24-105mm f/4 L IS USM - Focal Length: 24-105mm - Maximum Aperture: f/4 - Filter Diameter: 77mm - Image Stabilization: Yes Thank you for viewing. I am selling this to purchase a new camera. This product has been used for over 10 years. I had it repaired once, and it is currently working fine. There are two spots of dust inside, but it does not affect the photos. The zoom action is somewhat loose. I haven't used it much recently. It has been stored in a dehumidified storage unit (for about the last year). Please understand that this is a used item before purchasing. I will include a lens filter (with a thin scratch). Please decide whether to use it. The lens hood is not included.
