Which adapter for these old lenses


I have a Pentax Q and I have some old lenses:
Sigma 24-135 f2.8-4.5, Sigma 28-80 f3.5-5-6 macro, for Nikon and a Pentax A 50 1.7 plus some unmarked 100mm and 300mm that where use on an old pentax some same fit as the pentax A50.
As I don't understand much in lense fitting size I was wondering if I could use these lenses using an adapter?
I'm looking at the Fotodiox 11LA-PK-PK-Q, would that work with these lenses?

That adapter will only work for the A50 and the unmarked K mount lenses. Not sure what adapter you'd need for the Nikon lens.

Welcome aboard. As Guakala said, that one will work with the Pentax lenses and any K mount lens. Here is a good thread on adapters:

That adapter should work for the K-mount lenses but you will need an additional adapter for the Nikon mount lenses. I don't think Fotodiox makes one, I can't find it on their site. There are adapters available on eBay though.

Welcome, adapting long tele lenses was the reason I got the Q, but I found it could do much more, and fun to boot. enjoy the learning experience
