Last year I got a Asahi 6x7 to K Adapter with Nikon mount. I have to replace the Nikon mount from the K mount from a cheap Pentax-A 35-80mm f4-5.6. Fortune! I did not trash the remaining lens.
Today I remember having that junk lens and take the wide rubber form the 35-80mm and it perfect fit on the old Auto Yashinon DS-M 55mm f1.2 Tamioka, Wow!
P.D.
This method Do not shrink the rubber, at least in this particular model I tried about 10 cilcles times: I-> boiling water II-> cold water III-> 5 seconds in the microwave.
Next thing I never try was to pass the rubber on a hot surfase (hair iron?) but I considered it potencial destructive and I want to keep the original rubber.
You guys, thank you.
