This is a TAMRON F2.8 constant aperture zoom lens for NIKON F mount. Operation has been confirmed. It focuses cleanly and quickly from infinity to the closest distance. [As you can see in the 2nd, 8th, and 9th photos, there is mold on the front element.] However, the rear element (11th and 12th photos) has no visible mold and is in a clean condition, with no effect on the image quality. Regarding the hood, there is a chip on the inside of the hood (not on the lens side), and it tends to come off unless you get the hang of it, so it's treated as an extra. The exterior is very clean, including the tripod collar, as it has been used only a few times. It has been stored in a dehumidified storage. Thank you for your consideration. - Brand: TAMRON - Model: Zoom Lens - Compatibility: NIKON - Features: With Hood - Lens Diameter: 77 - Cap: With Lens Cap Thank you for viewing.
