This is the Z-mount version. I purchased this here and used it several times for shooting, aiming for the Lemon Comet. I am selling it to organize my equipment. From a layman's perspective, there don't seem to be any noticeable issues. The original Tamron lens cap, rear cap, and lens hood are included. A 70-300mm zoom lens compatible with NIKON Z mount, with an aperture of F/4.5-6.3, suitable for various shooting scenarios. - Brand: TAMRON - Model Name: 70-300mm F/4.5-6.3 Di III RXD - Compatible Mount: NIKON Z - Accessories: Lens hood, lens cap - Focal Length: 70-300mm - Maximum Aperture: F/4.5-6.3 Thank you for viewing.
