A TAMRON zoom lens with a focal length of 28-300mm. I'm a beginner with cameras, so I don't know the details, but I used it with a PENTAX camera. The cap says Nikon, but it's a K-mount lens. Please note that I lost the original cap and am using a cap from another product. I think there shouldn't be any problems, but I don't have much knowledge, so please consider it as a junk item. - Brand: TAMRON - Focal Length: 28-300mm - Filter Diameter: 72mm - Maximum Aperture: f/3.5-6.3 Thank you for looking.
