Dual gain stack sensor, nice. 1 second preshooting. Nice as well.
This has the same <0.8 microsecond claim that was in a rumor awhile back. 1/1250 second is 0.8 milliseconds, not microseconds. So I am still finding that odd as nothing else I have seen is with 3 OoM of that. If correct.
They took the page down, but I could also see the APS-C sensor mention at the bottom of the specs if you clicked on 'more product info', so this smells like someone made an oopsie.
Guys...this spec sheet is a copy and paste of the CR post from January leaked from Chinese site.
I doubt this is true as Adorama copied it almost word for word including the odd verbiage about the DR which would never be a line in an official Canon spec sheet.
