A few extra notes about these lenses:
-If you have the m39 version with a m42 conversion ring at the back, beware that if you put the ring on backwards, the lens may mount incorrectly on to the camera. In this case, the numbers that should be facing you will be towards the side of the camera. Simply check the m39-m42 adapter instead of going through other things first.
-Some of the older versions have a rear group that screws to the main assembly that you can reach without disassembling the lens. You can control infinity focus by adjusting how far that group goes in/out. You may even be able to get infinity focus on Nikons without any major modifications. Have no idea about the optical performance though.
-Just like the test posted on the previous page, Helios 44 models can reach a more than adequate level of sharpness when stopped down. Don't disregard them for soft focus, one trick ponies.
-Later versions with click apertures are really easy to modify into clickless aperture. Just disassemble the lens and remove the small metal ball. You don't even touch the optical assembly.
