End image description.

I needed to service a really old camera lens as the focus ring was all but seized and I had to remove 7 of these tiny little monsters just to get deep enough to remove the old grease that was basically glue after all the decades.

Unfortunately I couldn't get all the way in as I needed a specific tool to get the last internal ring off so that I could fully clean it.

But the focus ring now moves so that's a win, I'm hopefully going to find the tool I need so I can fully service this tiny monster though. Which means I'll have to dig into it again.

Edit: Of anyone knows exactly how to disassemble a Vega 7e camera lens I'm all ears BTW, I'd love to see how it's supposed to be done.

Edit 2: I was able to work the grease into the focus rings, unfortunately using calipers didn't help much in terms of getting deeper into the lens in the way I needed to.

If I understand correctly - you have trouble removing a screw ring. There is a specialized tool for that:

Buuut, if its not too deep in the case - you could unscrew it with a caliper.

Thank you for your service. I learn something everyday.

I don't know why I didn't think of that

I have calipers, not like the ones pictured but they'll probably work

Edit: They did work, but unfortunately I needed more tools to dig deeper. Good news is I was able to get the new grease where I needed and was able to work it in. It's smooth as silk now.

That was nice of you, mate. Be well, good fella

set screws are typically a hex bit. If it’s an American product it might be an imperial hex, anywhere else it is likely a metric hex.

It's an old Soviet camera lens, all the screws were flathead screws

Yeah it's some pretty cool glass
