Thanks for the all answer. So I guess it's not related to optical quality, I thought it was one of those optical flaws like CA.
The other possible reason is the coating on the Helios, since I never get similar phenomenon with my other lenses with multicoatings. I have another lens with simple coating, my vivitar series 1, but it never shows similar thing, but then again I dont use it a lot, which I should for now.
I remember I read somewhere that *istDS is very sensitive to infra red, maybe the combination of DS IR sensitivity and Helios poor coating cause this phenomenon? Just now I've tried to reproduce the thing but I failed, have to try more I suppose.
One more thing, when I open the image in photoshop, I notice that the red spots have almost white color in red channel and absolutely black in the green and red channel. Thoughts?
