Description: Helios-44M would have been a standard lens for the first Zenit with a “blinking” aperture, for example, Zenit-EM or Zenit-16. The letter “M” in the name indicates that the lens is equipped with a “blinking” aperture. this means that when using such a lens, framing and focusing occurs with a fully open aperture, and it closes to the working value only when the shutter is released. PC186557At the base of the lens there is a special metal pin - a pusher. In order for the diaphragm to close, a plate inside the device presses on this pin. The plate, in turn, is set in motion either by the effort of the photographer pressing the shutter button (a more common option with Zenit), or by a spring that releases the shutter (as, for example, with the Zenit-16).in the photo here and below, on the left is Helios-44-2, on the right is Helios-44M. An important feature of the Helios-44M is the presence of a switch between manual and automatic aperture control. This lens is the first of the “mobility” ones, and maintaining compatibility with older camera models was considered an important matter. In manual mode, the aperture closes when you turn the corresponding ring on the lens. In automatic mode, the diaphragm does not respond to the rotation of the ring. To close it you need to press the pusher. On devices without a blinker, there is no way to close the aperture in automatic mode.

From now on, for all lenses with the letter “M”, the aperture ring has moved to the place closest to the camera. This is understandable, the diaphragm is controlled from the pusher and is located closer to it.
