... 3D video with the Sony TD-20. 21mm base, 35mm focal equivalent lens....
Little base but it is very good. No adjustment, no discomfort, no eye divergence....
I attached a slide too, what shows the possible cause of the value of this 21mm base.
Time ago I saw, Duke wrote about the satisfaction regarding the little base.
