There is trouble with assembling, because the rear part can't be disassembled it's not easy to put anything back together (focusing guide, aperture control and aperture stop down control).
Anyway, you will start with front ring, which holds nameplate ring. Just unscrew it entire. _________________ .: APO-Maniac :. |

Thank you. I found this link http://www.bigeye.url.tw/big5/d_cz28_2.htm (from some other post on this forum) and it makes me wonder. I know this is a different lens from a different maker but it's rear part looks identical. It seems there is no explanaion on the site but they managed to get an aperture ring and the whole rear part off. |

Because I have the same question, I'll bring this topic back to life. Can anyone tell me how to disassemble the Rollei Planar 50/1.8 (I actually have the Voigtländer Color-Ultron but the construction should be identical)?
I managed to unscrew the front ring (turn the lens to min. focus distance, then grip it with a rubber glove and turn counterclockwise). Then I removed the focus ring by removing the three screws in it, but now don't see how to continue.
The aperture coupling is broken (a spring and the aperture pin came out) and it's impossible to repair it from the rear. |

the QBM version I have is slightly different, but in principle the same, mine has a M/A switch so looks a little different inside. _________________ Film... and sometimes SD14, 5D2 and some other suff! |

Thanks, but the rear of my QBM mount Voigtländer is totally different from that M42 Ifbagon. Only the QBM mount plate can be unscrewed, but after that the rear is one solid block of metal, so disassembly should be done from the front somehow. The problem is that I cannot remove the lens assembly by turning it past the 0.45m mark. |

If it's the same as the Rollei then although it looks solid it isn't. There is a ring you can unscrew which exposes the screws. _________________ Film... and sometimes SD14, 5D2 and some other suff! |

In the 2nd post, BRRunner also says the rear cannot be disassembled. I don't see any "ring" that can be turned/removed, so the construction will not be identical to the Rollei then. The style of the focus ring and aperture ring is identical to the rollei then, but the contruction of the rear must be different. |

I guess they're put together differently then. But there must be a 'way in' somehow.
This is the ring on the german 'made by rollei' type. Just above the red M.

Thanks for the picture. Mine doesn't have that ring. It's also missing the M/A switch. The must have removed that for later models to cut production costs, making the lens more difficult to service in effect.

There is a link on the same site for 1.8/50.

If you cannot put all things back. Try to replace the aperture spring with another strong spring and put it in the reverse direction(step 7 to .

Phew! I finally figured out how to open it, but it does not open from the rear. You have to turn the lens to the minimum focus distance (0.45m) and then turn the lens assembly (inner focus helicoid) counterclockwise as much as possible, and then turn the outer focus helicoid clockwise, and repeat this process until the lens assembly is completely out.
The part that was attached with the two screws and one part of the aperture mechanism kept getting stuck, which is why I thought at first that the lens could not be opened like this. You have to look carefully what is happening.
Edit: I managed to attached the spring that normally keeps the aperture open to the aperture lever from the other side, so now the aperture is always in stop down mode.
Now the challenge is to get it back together again, which may be difficult because I have to screw the two parts of the helicoid back together again while lining up with the arm from the aperture ring. |

As far as I remember, there is three positions which you can screw the two parts. You have to try which one is the right position. After you find the right posisiton, you have to adjust the infinity position.
If you will not change your lens to QBM mount, open it from the back is much more easy as it does not require you to adjust the infinity and you don't need to care about the original aperture mechanism. _________________ https://lensfever.com/

The good news that I managed to get the lens back together, with working aperture control(!) after a lot of pondering and trying. I've had to take apart the helicoid like 6 or 7 times because the aperture coupling wasn't correct or I didn't get infinity focus. You can see this already when you put the focus ring on: there is a gap between it and the lens, which should not be of course. I still do not have perfect infinity focus, but I'll get there. |

The mount adapter was taking quite a lot of force to mount to my 5D, by the way. It's better now that I unscrewed the part that's there to push down the aperture pin. I think it was pressing against the mirror box, above the electronic contacts. |

Adjust the infinity after you put the conversion adaptor to the lens. I don't sure why your lens can focus beyond 0.45m but I would suggest you check the alignment of the focusing mechanism.
My converted lens mounts to my lens easily. Make sure it is installed properly.
P.S.
If your 5Ds mirror is unshaved, the mirror will hit the protection ring on the rear when you focus infinity. _________________ https://lensfever.com/

Will it mount on my 5D MkII or will it hit the mirror ?
If it hits the mirror, is there a simple way to solve this issue ?
