This actually refers to telecentric lens design, meaning having the optics designed in a way that the light will hit the sensor more linearly without too much straying off, and this was already adopted by Four Thirds system lens mount in 2003! Yes, Olympus and Panasonic that started the Four Thirds DSLR system, with Olympus releasing their first DSLR Olympus E-1 in 2003 alongside their first fully realized telecentric design lens, Zuiko Digital 14-54mm F2.8-3.5. These technical concerns and approach to optimize lens mount and subsequent optical design have been fully implemented by Olympus and Panasonic’s Four Thirds system 16 years ago. 16!
