Helios-44-2 2/58 has a ring mechanism for aperture presetting. This ring makes it possible to choose suitable values for shooting: F/2, 4, 2.8, 5.6, 8, 11, 16. We should emphasize smooth rotation of the ring, which lets choose intermediate values for the frame. The feature can be perfect for video-shooting; the design is made of an 8-leaf aperture forming small polyhedra cavities.
Describing the focusing features we can say that the ring rotation value is 270 degrees, which greatly helps to setup the camera in an appropriate way. Focusing will be convenient, during focusing the front lens doesn’t rotate, but instead the body frame is lengthening.

In the shot you will notice excessive sharpness in the central area of F/2.0, if the aperture is half-covered, the image on the edge and corners will be significantly stabilized. Light yellow color is typical in H 44-2 2/58.
