Focusing ring does not have enough resistance.

[Markok765]

I dropped my 55mm lens a long time ago, and repaired it, but the focusing ring does not have as much resistance as my other lenses. This makes focusing less precise. Any ideas how to fix this?

Does it make focusing less precise or make the adjustments more pronounced and make it easy to pass your sharp focus point? If it's just a matter of passing your sharpness just slow it down, which isn't bad advice no matter what. Just slow things down. (Preaching to the choir, here) I should take my own advice more often. But if it actually damaged the lens, it might not hurt to have a shop look at it to give you an estimate. Might be worth it, might not.

Keep it light, Marko

I guess I'll slow it down. I am using a tripod anyways!

It's also probable the old drying up damping grease in your other lenses is way stiffer than when it was new. Old grease dries up and gets stiff, to the point where you can't move a focus ring. The tech used new possibly lighter damping grease than the factory one and thus there is a big difference.

Well, I fixed it, and it was like my other lenses in terms of resistance prior to it falling/me fixing it.

Good call, Bob. Selling auto parts, you'd think that would occur to me, huh?
