Hi there, hope anyone can help me with this.
I purchased a 135mm 2.5 X-Fujinon that appears to be in like mint condition. According to the previous owner, the lens has never been used since purchase and has never been taken apart for service either.
Problem is, that the lens does not focus to infinity. I checked on two Fuji SLR bodies. Focus is far off, as if one would use an extension tube, not just a little.
Any ideas on what could cause the problem?

What are you looking for exactly? It looks like every other 135/2.5 from the outside.
Here is the type of lens https://www.flickr.com/photos/subart/16947729708 |

Same symptom as lens with focus helicals not properly aligned -- helical threads have multiple start ons.

Possible but I would first check whether the focusing ring screws/tape can be freed from the helicoid and turned to the infinity mark when the focus is there too. Do not know the Fuji construction and the focusing ring max turning angle but it can be way off just on that simple fault.

Where would anyone typically look for "focusing ring screws"? Do I have to remove the rubber ring? |

Most likely the reason is the focus ring has slipped. You will definitely have to take of at least the rubber grip. If there are no adjustment screws under it, you may need to go deeper. |

On the Minolta MD models it can be a tape overlapping the slit between the focusing ring part and the part that connects to the helicoid. In other lenses it can be three grub screws where the two overlap one another. On a Mamiya Sekor three screws behind the lens beauty ring so lengthwise to the optical axis. I guess there will be a dozen other constructions.

Thanks guys, turned out one of the lens elements inside got knocked out of position. I unscrewed the front lens, pushed the loose element tightly back in and now everything looks awesome in the finder. |

Not sure how a picture would have helped. See my first reply. Thanks. |
