This lens seems a home made lens , what you think ?

A photo of the front ring that shows the writings please?
Judging from the black bottom part of the barrel, I would say that this is (or at least originally was) a lens for the Contarex.
Have you checked the mount?

This lens not yet in my hand, I just bought it with "Buy it now" I have extra information only it has M42 mount, perhaps seller wrong.

I'm looking forward to hear about this lens, Attila.
People did the strangest things to CZJ lenses.

I've got a copy that has been permanently adjusted to the EOS system.
So it now is a CZJ 4/135 with EOS mount. Wink

It works excellently!
The job was done by a former Leitz mechanic, I've been told.
Well, it looks like it. Some professional adjustment, really.

This is the way it looks like at an EOS500:


And these are some photos I took with it:







All shot in Hamburg, last late summer.

This is the lens:



This blue "ring" was needed to adjust the lens constantly to the eos system.
The mechanic told me that the new mount caused a different register compared to a M42-EOS-adaptation, so this distance ring became necessary.
It works also at infinity...

And he said that he only made this one lens. So this home made lens might be quite unique. Wink
Well, at least that is what he told me and since the (very nice and helpful) experts at ZeissHistorica.org did not know anything about this blue ring, chances are high he told the truth.

I like the "panorama" in pic#1 !! Wink
And great bokeh - yes yes we call it that way here Wink

No seriously, great Zeiss lens - but is really there a Zeiss lens that is not great?

Hey Carsten, that is really a nice custom work! What system was the original lens for? Contarex?

The guys at ZeissHistorica.org found out that referring to the serial number it originally was a M42-mount.
Which made me wonder why somebody went all the way to a special adaptation.
Maybe the mechanic wanted it to be extra firm...
I don't know, but it works and looks great! Very Happy

Yes, strange because seems he used an EOS adapter as custom mount.Perhaps he wasn't happy with M42-EOS adapter Smile
