Pentacon / Praktica and Pentax

13 and 12 researched events on one shared scale. Pentacon / Praktica 1919–present, Pentax 1919–present.

The axis stretches where either maker has research and collapses where neither does, so a year sits opposite the same year on both. Event counts differ because research depth differs, not because one company did less.
