The lenses are: "deitz multi-coated auto tele converter 2x for pentax-k", and a "auto makinon macro lense 1:2.8 f=135mm"
Yes, both of those, the 135mm macro prime lens and the 2x teleconverter, are compatible with modern Pentax dSLRs like a K7. The teleconverter isn't worth much, maybe US$10. That macro prime, which often sells for US$30-$50, is... well, from what I've read, it breaks two rules: 1) it's hard to find a bad 135mm lens; and 2) macro lenses are usually sharp. It just doesn't have a good reputation. Sorry.

All the old lenses i have are Pentax Asahi and they are from the 80's. And thanx for the focal length answer
If there are any of those old lenses you don't want, just let us know and I'm sure someone will take them off your hands. Seriously, many old Asahi Pentax lenses are rather highly prized now. Tell what they are and we'll likely drool.

For SR, use whatever focal length the lens is. If anyone mentions that obscene term CROP FACTOR, cover your ears and eyes and turn away. A lens remains the same focal length no matter what camera it's on.
