Short back focusing distance není konstantní?

Je tohle totéž co flange distance? Myslel jsem že pro konkrétní bajonet a značku jde o konstantu.

Short back focusing distance
By reducing the distance between the rear lens element and the sensor, a more compact construction is possible.

XF18mm / Back focus distance: 11.0 mm
XF35mm / Back focus distance: 21.9 mm
XF60mm / Back focus distance: 21.0 mmance: 21.0 mm
