helios has that weird bokeh. jupiter is more "normal". at least those that i had opportunity to use.

I ended up selling the helios because I didn't like the build quality of it. Very hard to pull focus without turning the whole lens. Since then I've gotten Lomo and Konica Hexanon lenses and I love them.

i never got to the pro level of pulling focus :) i have helios 44 because of the easy and fun modification and jupiter 37a as it was chap 135mm lens when i was first starting with photography. and i suck at selling things.
