If I have understood everything right, it seems to me that the *ist has 3 rows of sensords. The top and bottom row has 3 sensors and the middle row has 4 sensors. The outer sensors of the middle row are linear sensors, sensitive to vertical lines. The central sensor is probably a cross sensor, and probably 2-3 more.

I believe we have 3 possible layouts here:

3 cross sensors (in the middle column or the middle row except the two outer sensors)

5 cross sensors (in the middle column plus the middle row, except the two outer sensors)

9 cross sensors (all sensors except the two outer sensors in the middle row).

Best wishes,
Roland

I would like to clarify: When trying t focus on a simple horizontal line on a white wall, the centre sensors and 2 or 3 adjacent sensors were able to focus no matter whether I held the camera horizontally or vertically. I do not know whether these sensors are real cross sensors, but in thsi my test they offered the same functionality like cross sensors. The sensors on the very left and on the very right were able to focus only with one orientation, they obviously are vertical sensors.

This is not a rumour but the result of an experiment.
