Sony E-Mount lens chip tap

Written by dashie — April 28, 2019

I'm interested by a reverse ing of the Sony E-Mount protocol and I needed to make a "tap" to dump serial datas.

Looking at the back of the lens, flat pads, on bottom, pinout is (left to right):

  1. lens gnd
  2. lens pwr
  3. logic gnd
  4. body vd lens
  5. logic pwr
  6. lens cs body
  7. rxd
  8. txd
  9. body cs lens
  10. lens xdetect

The pins which have been broken out are: 3, 4, 6, 7, 8, 9

Sony E-Mount result

Sony E-Mount pins 1 Sony E-Mount pins 2 Sony E-Mount pins 3
