Hi, bought nice Helios-44M-4. There is a normal pin (at 12 o'clock in the picture below), and a thingie (at 5 o'clock):





For what camera body is this second device? Seems to do exactly the same as pin.

For camera body to know what aperture lens is set. Don't know camera(s).

For open-aperture metering IIRC, on one of the later Zenits.

Yes, thank you, Zenit it seems to be.
