Yes, I was aware of that, but I am not a contortionist.
I received a response back from Mr. Bertram Hoenlinger of Zeiss.
Zeiss will swap out the flange at their factory in Oberkochen for a cost of 60 Euros + shipping, or they can ship me the parts and I can do it myself. The usual warnings about lens calibration and warranty maintenance are accompanied with the latter.
Here are the part numbers for those interested:
Mount for 28mm ZM lens: #1469-516 EUR 26,--
Screws #1460-876 EUR 0,50 (4 pcs necessary)
You can e-mail Mr. Hoenlinger at
hoenlinger at zeiss.de and request the parts. Zeiss only accepts bank wire transfers.
Please note that these parts are for the
Biogon T* 2,8/21 ZM
not the C
Biogon T* 4,5/21 ZM.
Here are some more test shots. This time I got to use the External Viewfinder and I have to say the framing is spot on.
