Can't find a logical way to access the inner helicoid. On the CZJ lenses there's a screw holding it in place but I can't see any screws on the inside or outside of the lens whether at infinity or minimum focus. |

Try peeling off the grip. There are probably set screws holding it in place the outer focus under there, which will lift off once removed, allowing you to freely rotate all the internal components . These would also be used to set infinity focus, too, as Pic #2 clearly shows the infinity stops attached to the outer ring. |

I'm afraid the grip is metal and a part of the barrel. |

Are you sure? As far as i remember, the grips on CY lenses are made of rubber. Check the fifth photo on this link http://www.bigeye.url.tw/big5/d_cz85_14_2.htm , the screw under the grip is used to adjust the infinity. _________________ https://lensfever.com/

You're right I just peeled it off, thank you. |
