I'm hopeful that the time spent developing its sensor stabilization was used to create something very impressive and reliable. I also hope that Canon has witnessed some of the possibilities with this tech like high resolution and night sky modes from other brands and taken things a step further.
Multi-shot mode that is actually useful in that it works with flash (unlike every other mirrorless camera) making high resolution stills a very useful studio features rather than a headline grabbing/clickbait spec.
Multi-shot without flash is not a gimmick and usable in many situations. I would say most, like landscapes. With flash i think its harder to implement because of flash recycling times between each shot.
Even though I know it’s next to impossible to create without reducing image quality and it may be large due to all glass in it.
I’d LOVE to see an RF-EF adapter.
Since they noted, no more EF Lenses this would be a good trade off.
