Pentax MV/MV-1 cameras

I loved my Pentax ME Super, which replaced the K1000 I bought in 1976. Of course, no one had invented that indispensable adjunct to auto-exposure then, the exposure lock button. With that, you can rule the world. The only auto-exposure cameras I still use without one are the OM-2ns, buts that's down to totally irrational love, so don't ask me for any sensible reasons.
