Interesting test. Did you try the EFC on the NEX7?

Guess the test was performed without the electronic first curtain enabled on the NEX-7, because if EFC was enabled there shouldn't be any vibrations before and during the exposure (except maybe a bit from the aperture). A pity that the A7R doesn't have EFC like other recent Sony cameras (including the A7).

P.S. - Took another look and can see now that the electronic first curtain actually was ON on NEX-7... but if so, where does the vibrations before and during the exposure come from?

I saw exactly what you are saying, went back and checked 75 images, that image is EFC OFF, I mistakenly said it was ON. Thank you for pointing it out.
