I have the Helios 44M it have only 8 apature blade. But it doesn't really matter because the fun begins at wide open
Well I agree with you!
Mine has six aperture blades. It would be great if it had more aperture blades or a least if it were better rounded...
I also own a Jupiter 9 MC lens which has 15 aperture blades that are perfectly rounded. It helps because sometimes I close the aperture to f/2.8 to reduce the COMA and bokeh circles remain round!
I can do it with my Helios or Nikkor AF-D 50mm f/1.8 because the bokeh circles change to polygonal circles when I stop down.
The Nikkor has great colour rendition and better flare control, but is softer wide open that my Helios... If I stop it to f/2,0 or f/2,8 in case I have light sources that are spot, the bokeh circles start to be edgy.
So the Helios in an one way solution and I control the flare with lens hood and if it is not efficient, I use my hand for shade with focusing becoming real hard with only one hand handling the camera.
Anyway.
You cannot have everything in life.
