This is the Helios-44M-6 its the big brother of the famous 44M-2. Difference is with higher number they have higher resolution index it is 58mm with f2 opening , 8 aperture blades,45cm minimum focusing distance 52mm filter size. For the performance it has the typical swirly bokeh character you expect with Helios much cleaner than 44m-2 and 4 am actually amazed with the shot I got, real interesting on video as well the manual focus ring needs some getting use to it’s not as easy to turn as the 44m-2 and it’s heavier so needs some kind of stabilization,in my opinion this lens shines in green area background.
