I turned the aperture from 2 to 16 and back to 2 a few times quickly and it,s still stiff but much easier than it was. I guess the lens hadn,t been used for a while.
my other helios 44-k 4 aperture turns very easily but clicks between aperture numbers so I guess the 44-2 with stiffer aperture will be easier to use. _________________ Paragon 500mm F;8, Helios 70-150mm F;3.8, Mirage 100-200 zoom F:5.6, Photax 28mm F:2.8.

Hi Thomas, old USSR lenses are often a bit stiff. The grease they use for damping is very thick, it's the same stuff they used for tank gun turrets I think.
Sometimes you can soften the grease by working in a tiny amount of liquid lighter fuel, but most times it makes the grease feel like sand. To do a proper job you'll have to dismantle the lens, clean off the old grease and apply some new. It's not difficult if you have the right tools - here's an article on how to do it:

Usually if you keep working the aperture it will clear it up, and keeping the lens warm will help but you might have to clean and re grease it as Peter says- its not so difficult to do |

I've used the lighter fluid method and like peter says.....sand!
I've also tried WD40 and that seemed to do the trick. However, this worked for me and I do not promote this as the way of cleaning threads. _________________ Casual attendance these days |
