The Helios 44M-6 features a manual aperture ring. This lens typically has two rings: a preset aperture ring and an actual aperture ring.

For focusing, it is often recommended to open the aperture to its widest (F2) for a brighter viewfinder image, then stop down to your desired shooting aperture before taking the photo.
