It would help if you said what lenses exactly. Your title says "F lenses on K-70". To me that means the Pentax F series of lenses which do focus automatically and should work fine on the k-70.
So do you mean you have F series lenses that are not working or that you have lenses that are not auto focus and likely not F series?
If your lenses have the 'A' setting on the aperture ring make sure the aperture ring is in that position and everything should work properly. If you want to use the aperture ring in stead of the 'A' setting then there is a menu setting you need to change, I believe it is called "Use aperture ring" or something similar but as long as you have lenses with an 'A' setting and use that you do not need the menu change.
