Focusing Tab cho Helios 44-2

I never had a lens with a focusing tab and I wanted to give it a try.  and inspired by Leica lenses I created a focusing tab for my Helios 44-2. 

I have to say it was a great improvement to the manual focus experience. It offers additional leverage and it creates a slot for my index finger to rest in and easily pull focus.

While most of my soviet era lenses you can probably do this with just a ring and the tab the helios has 15 indents around its body so I wanted to leverage them for a better fit.
