Does anyone know the correct order to dismantle the lens Petri 1.8/135 for service purposes (stuk apperture, relubing of focusing helikoid, cleaning the optical lensblock)?
Or link where is shown and described?
This lens can be found under the name Spiratone, Accura, Mitake, Polaris, Admiral ...
Thank you!

Is it normal for the second and third lens (from the top) to touch each other?
By the assembly that bothered me if properly set them, because indeed they touch each other in their center.

To be very close is ok, but really touching each other in the center seems for me wrong. _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html

It is an old post, but I have seen the same info repeated elsewhere... so better give the right details, in case someone comes to this page following a Google search.
The brands mentioned in the first post do not refer the same lens.
The Petri CC is like my Raynox Polaris (M42), and was made by Yoshida Industries (Raynox).
The Mitake-made one is like my Porst in PK mount.
Here is a diagram of the optical designs of the various f/1.8 135mm lenses, with pics showing how they look and details about most of the various rebrands (Copyright Alf Beharie)
