Megadap ETZ21 issue with Nikon z7ii -- PROBLEM SOLVED!
I have used a manual focus Voigtlander 21mm f3.5 lens connected via this adapter to my Nikon z7ii for the past 3 years without a hitch. Then I bought a Tamron 150-500mm lens and decided to update my firmware to 1.70 on the Z7ii. The next time I connected the Voigtlander lens, it no longer functioned: the f number is missing and shutter won't release.
I updated the Megadap ETZ21 firmware just fine and tried versions from 1.33 to 2.02 without any solution.
I'm hoping someone could send me an earlier version of the Z7ii firmware to see if going back solves the problem. I have not reached out yet to Megadap, which some folks have found hard to communicate with.
Thanks for any help you can provide
