Q: 7. Is nikond7100 right for a pantax af

A: I am not sure I understand your question exactly, but if you mean:Will your Nikon d7100 be able to auto focus your Pentax lens using this adapter? the answer is, No. If you are asking is this the right adaptor for your pentax AF lens? then Yes. Pentax has not changed their lens mounting type (645A) since the original 645 came out in 1984. They have created the 645A, 645FA, 465FA2... lenses, but the difference is only the addition of autofocus contacts and not the flange distance. If you look up their latest camera the Pentax 645Z the specs say it is compatible with a a 645A style lense. So, all that to say if you are trying to put a Pentax 645 lens on a Nikon F mount then this adaptor will get it done. I purchased the Canon FD to Nikon F adaptor and it works for the most part. I have a few lenses where the back focus is not correct, but other than than it works fine if you don't mind manual focusing.

Q: 8. will this work with a pentax ka mount?

A: Yes, it should work, but I have not personally tested it. As far as I know, the KA lenses are very similar to the K, but have autofocus features whereas the K lenses are manual only.Hope this helps!

Q: 9. If using on an A7 ie full frame camera, will you have to put the camera in crop / super 35 mode? Or can the full frame be used?

A: It can be used in FF mode, assuming the Pentax lens is a FF lens.

Q: 10. Does anybody know if you can use the auto focus 645 pentax lens to be electronically connected via an adapter to a nikon D800 SLR? I will be grateful for any help. Thanks, John Dufton

A: There is no electronic connectivity between Pentax AF lenses and a Nikon digital body with this adapter. Manual focus and manual exposure control. If you chose this route, you're going old-school so be prepared to miss a few shots unless you're stopped down for a wider DOF.
