Volna 9 (M42) experience?

I own an Industar 61L/Z 50mm/2.8 lens (M42) which I am very fond of because it has a very l-o-n-g, smooth focusing helix. It lacks somewhat in contrast, but so what :slight_smile:

Here is a sample. Nice bouquet, eh?

Now, another Russian company made the Volna 9 Macro lens.
Quite similar. Or at least almost the same…

Is there anyone having hands-on experience from a Volna?

Have fun!
