Last night I inspected a Heilios 44K-4 58mm f/2 lens (in K mount) that I had and found lots of dust/haze inside. So I decided to take it apart and clean all of it's lens elements.
Over the years, I've done CLA jobs on dozens of lenses. I had never taken part one of these cheap Helios lenses before. But I found that this was by far the simplest and easiest lens to take apart of any lens I've ever worked on.
This would be a terrific lens for someone to work on who's wanting to learn the basics of taking a lens apart and cleaning one.
The only tool needed is a
spanner wrench. By the way, I used 99% isopropyl alcohol to clean the glass lens elements.
