>>3886828>Another related reason is the nature of digital sensors--with film, the film grains don't actually give a shit what angle the light hits them. With digital, it works a lot better if the angle is closer to perpendicular to the focal plane. This necessitates a more telecentric design so the light doesn't come out of the lens at very oblique angles at the edges.That's true for Sony sensors and similar trash, Leica doesn't give a damn. Microlenses baby, oh yeah.
