Hello, please refer to the size chart or capacity display on the details page. 

Hi,this is not compatible. 

According to the K&F concept homepage, the surface treatment for this adapter is "anodized" and that means anodized. Anodised layers are used to improve the appearance and functionality of the surfaces of aluminum materials; With the adapter, the aspect of wear resistance (contact surface to the camera) should play an important role (a black lacquered connection surface would probably start to "dissolve" after a few adaptation processes). 

The adapter is designed for Nikon lenses, including D mount. If the Tamron fits the Nikon D80 it should work. As for the lack of aperture ring on the Tamron ... not sure about that. Perhaps the Nikon D80 has an in camera aperture selection. 

1. You could consult us or search the mount information online
2. You could find the mount information on your instruction book when purchase the lens/camera
3. The mount information may be showed on front of the lens, side of the lens, rear of the lens or on the lens cap, usually it is a 2 or 3 letter code such as: CN, FD, OM, MAF, NK, N/AIS or F/AX
