I-61 with stiff focus

[whereshaldo]

I've got an I-61 that is a little too stiff on the focus, sometimes to the point where the lens unscrews. Greyhoundman cla'd this lens but its just too tight for me.

I just want to add, that in no way do I feel like Greyhoundman did a poor job with this lens. I got a Z 4K and a I-61 from him that are spot on! For my tastes the focus ring is a bit stiff, but I think for others it might be perfect. I'm just used to my sloppy loose GSN.

Are there instructions for fixing the focus tightness?

hi!
it is pretty easy to service that lens, follow the instructions on http://homepage.mac.com/mattdenton/photo/cameras/industar_relubing/index.html

I relubed 2 I-61s ofmine by following the above page - it is pretty straightforward. I used Lithium Lubricant Grease which I got from a bike shop. Now there are way looser than my Yashica GTN focus.

It's all about the lube. Somewhere there's probably a continuum of the various greases. In my experience, Tri-flow chain grease is stickier than Radio Shack Gel Lube, which is stickier than Finish Line Synthetic Grease. As soon as the absurdity of relubing my scratched I-61 for a fourth time wears off, I'm going to try Sil-Glyde. I'll bet lithium grease gives the lightest effect.
