Yes, it is indeed Nikon f mount. 

Dear Customer, so sorry to tell you that this adapter won't allow your nikon 1 s1 lenses to mount to my canon t2i. 

hello， The Nikon-EOS adapter ring fit for nikon AI mount lens and canon EF camera. so the adapter ring fit for your Nikkor 55mm 3.5 ain’t lens on to canon 80d 

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. 

No the other way this is to be able to mount the Nikon lenses onto the micro 4/3 camera body
