TAMRON 90mm F2.8 macro lens, ideal for close-up photography with a 1:1 magnification. - Brand: TAMRON - Model Name: SP AF90mm F2.8 Di MACRO (272E) - Focal Length: 90mm - Maximum Aperture: F2.8 - Macro Function: 1:1 - Lens Hood: Included Thank you for viewing. This is a Tamron macro lens for Nikon F mount. I am selling it because I have switched to a Z mount digital camera and no longer have a use for it. To the untrained eye, there appears to be no dust or mold inside the lens. I will include a Kenko Pro1 Digital protector.
