Thank you for viewing. This is a listing for a TAMRON 150-500mm Z-mount lens. The category is listed as F-mount, but it is a Z-mount. I purchased this on Mercari about a year ago, but I am selling it because I bought a new lens. I have taken it outside about 10 times. There are some scratches on the hood. When not in use, it was stored in a dehumidified storage unit, and there is no cloudiness visible inside the lens. I have a cat, so please understand this before purchasing. If you have a desired price, please negotiate a price reduction. High-performance zoom lens with a focal length of 150-500mm. - Brand: TAMRON - Model Name: 150-500mm F/5-6.7 Di III VC VXD - Accessories: Lens hood - Focal Length: 150-500mm - Maximum Aperture: F/5-6.7 Thank you for viewing.
