But the real advantage of Sony is their mount dominance.
Voigtlander is balls deep into E-mount because their CEO is an M-mount shooter and Sony shooter.
They are the one company who could have ported all of their lenses into RF and Z with ease(they are just manual focus lenses), but haven't bothered to do so, because of no interest from the CEO.
Tamron is balls deep into E-mount, but they are working to port their lenses to Z and RF.
Sigma mainly wants to do L-mount, but due to financial circumstances have to release everything for E-mount too.
Zeiss is also balls deep into E-mount. Loxia could have been ported to Z and RF ages ago, but 0 interest from them.
Samyang is the one who have gotten the furthest with RF and Z mount. But they alone are so tiny compared to the other four 3rd parties.
