The next photos are my first shots with this lens. I didn’t thoroughly test this lens, nor did I any compare yet.
My first impression is that indeed this Helios lens is sharper then the 44M 58/2. I am not sure about the bookeh yet if I am going to like it or not. Somehow this lens is also soft, like the 44M, and that gives pleasant results. At the other hand the bookeh tends to be nervous.
Well, see for your self..
