The Canon EF 17-40mm f/4L lens is a high-quality zoom lens perfect for shooting landscapes and buildings. The exterior is relatively clean, with slight whitening of the rubber. Please consider that this is an older product and may have some minor scratches. The inside of the lens is relatively clean, and I don't think there's anything that will affect the photos. Please consider that there may be some minor dust or fogging as it is a used item. The AF, MF, and zoom mechanisms all work without any problems. The sample photos were taken with a full-frame SLR camera, with no corrections or retouching. If anyone wants more detailed photos or explanations, please comment. You can get a discount on shipping if you buy multiple items. - Brand: Canon - Model Name: EF 17-40mm f/4L - Hood: EW-83E - Diameter: 77mm - Zoom Range: 17-40mm Thank you for looking.
