Say an old lens cant focus at infinity. It almost goes there,

Unscrew it. Find a keyring that is the same size and put it below the back element.

Also, I was all about infinity with the 44-2. There isn't really a point for having it, because you buy the lens for the swirly bokeh but then again don't get to use that if you're shooting at infinity.

yeah saw that fix in a couple youtube videos. then found some chink/slav saying this fix deteriorates image quality, that the Real Fix (TM) involved moving all elements towards the camera body, not just the rear element. what do you think?

I wouldn't suggest it. I'm not entirely worried about IQ rather than what the image actually shows and displays. Hell, the look may add some good feelings if it's tasteful enough.

im worried about getting the damn infinite available, since this is the only lens i have for this camera. not an helios, but as old, may be a tessar type. i might do this simple surgery, doesnt seem too complicated.

Plus if you fuck up you'll have to fix it so it's not a question of if you can, but rather when. And you can do anything given enough time.

You are welcome

take your helios and remove the rear element.

then throw it in the god damn trash because that's where it belongs
