Did you find a solution to this I have the same problem? 

Better is the sigma adapter...don't hesitate 

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. 

I actually have not received this adapter yet. It's shipping from China. Don't think that was disclosed in the ad. However, I do not believe this is for the Pentax Q body rather for digital and film cameras that take the Pentax K mount in its many variations. So I'm expecting to be able to mount my Leica M mount lenses on my digital and film Pentax K mount cameras, no autofocus or relay of exposure information, only to be used with manual focus and exposure. 

はい、ニコンF（Gタイプ）レンズアダプターが使用できます。当社の G タイプ マウント アダプターには、アダプターを使用しながらレンズの絞りを手動で調整できる手動絞り制御リングが備えられています。
