Congrats, Fred.
I also bought one on Ebay Japan recently as well, waiting for delivery.
I hope it is as mint as the seller is promising.

This is my 3rd copy I'm re-buying after selling 2 good ones I already had...
Obviously this lens causes some special variant of GAS, where no vaccine can help ...

Where do I find this Leitax-Adapter?

Hi Peka,
Good luck getting a great copy!

BTW, I bought the Leitax directly from the source. It's easy to install and the combination very solid:

I finally have a perfect copy of a like new lens. It was not easy though, and took some time:
I bought one in Japan 2 months ago that was advertised as 'near mint' and 'just cla'd'. When it arrived it was a pure disaster. Lot of dirt inside, lot of fungus on the central lens element, but it had a perfectly clear rear element, no haze, like new.
My local camera repair lab could not clean the lens, it was not possible to completely disassemble it and access the central lens element...
I found another copy, that was advertised as 'defective', 'just for spare parts'. The rear element was completely missing in this one, but the rest really was like new. So my lab combined the two defective ones and TATAAA:

Here it is:

It is perfectly sharp corner to corner from wide open at every focal length and perfectly centered.
Best @ F/5.6, after that diffraction begins.

This is a shot out of my window wide open @100mm, handheld. A7R4

BTW, the white dot on top of the power pole under the crane is a stork :-)

I am afraid to ask how much it cost to purchase 2 lenses and to then the labor cost to cannibalize both lenses to prepare one like new perfectly centered sharp copy.
