I remember I once owned such a lens (maybe with my Exakta in the early seventies).
To simulate a second ring you shifted the only aperture ring away from the body and turned it to set the hard stop.
At a second thought, I think my Pentacon 3.5/30 (= Meyer-Görlitz Lydith 3.5/30mm) is such a lens. Presently I cannot check it.
Yes. My early CZ Tessar and CZ Flektogon 1-ring presets have this configuration; however, my really, really, old CZ Biotar does not. It just dials the aperture up or down with no means of presetting the stop point.
There's no denying that using vintage glass has its learning curve given the variations -- Manual aperture, 1-Ring Preset, 2-Ring Preset, Auto with cocking lever, Auto with A/M switch, A lenses and of course the fully manual PK lenses requiring Green Button stop-down metering. In using vintage lenses, I love the connection between the photographer and camera/lens. The level of involvement and interaction means you've got more invested in the shot. It's all fun and the sense of satisfaction when a really nice image is produced is through the roof!!
Have I mentioned how much I love shooting vintage glass? :-D
