    Bonjour chers amis Nex!

    Is there anyone who has overhauled Industar 61? My focus ring is not completely smooth. Thinking it's just oil or grease missing.

    ISO 500, f/8, 1/160, time is 07:14 AM, today.

    More likely the grease in the focus helicoil has solidified. It's a fairly common malady in older RF lenses. I read somewhere (no idea where) that sometimes just racking the focus from end-to-end repeatedly will loosen it up. If not a CLA may be in order.

    Nice scene BTW. :)

    I've now overhauled the lens. It is like new! It was a quick and easy operation.

    Wow you've a lot more guts than me... I wouldn't dare try for fear of not being able to put it back together again!

    Well done!

    I'm curious... what type of grease did you use for the focusing barrel?
