Dans le test d’imaging-ressource, il est dit que Sony s’est attaqué au probléme pour le A7R III. Reste à vérifier ce que cela donne en pratique.
A7R Mark III image stabilization and low-vibration shutter
Interestingly, the technical presentation we received on the A7R III devoted a lot of attention to the importance of reducing camera shake and vibration in order to realize the ultimate resolution a camera is capable of. They made the obvious point about mirrorless cameras like the A7R III not having mirror slap to contend with, as in SLR models, but they also noted that the shutter mechanism in the A7R III is an all-new design, with greatly reduced "shutter shock" vibration, thanks to a newly-designed brake mechanism that slows the shutter curtain right at the end of its travel, preventing it from slamming into the bottom of its housing. Shutter shock has long been an issue with many mirrorless cameras, perhaps related to the fact that their shutters have to close and then re-open again during normal mechanical-shutter exposure. Sony claims that the new design of the A7R III shutter will greatly reduce this. (And of course, the A7R III's entirely electronic shutter in its "silent shooting" mode will produce no vibration whatsoever.)
