The Nikon Z9 sensor readout speed is something like 3.65ms and the A1 was something like 4ms. This is what I remember from either the announcement of the Z9 or shortly after.
No confusion. It's what was reported for the reason that Nikon was able to omit the shutter in the Z9
Being able to omit the mechanical shutter has been possible since the introduction of the A9 way back in 2017. These stacked sensor cameras are all mechanical shutter optional. Most people almost never use their mechanical shutter, many never have This capability has been improved on through the years with the ability to tune the ES to avoid banding, and get high flash sync speeds. Nikon didn't have these capabilities on release of the Z9 so needed to add them through firmware updates to match the other "shutter optional" cameras, and avoid these problems.
What Nikon is touting as an innovation in removing the mechanical shutter was neither new, nor a benefit. It was a cost saving measure. Innovations should advance the state of the art, and add capabilities. Nikon's deletion of a mechanical shutter did neither. In fact in rare side cases it removed functionality. Even the sensor protection shutter is nothing new, even Leica has had this feature in its mirrorless M series cameras since around 2006.
Steve, I mostly agree but the 1/160 sensor scan speed wouldn't really let you go to a mechanical only shutter because that would only allow a pretty slow flash sync speed. IMO, the A9/A9II needed a mechanical shutter for flash. The A1 could have had an electronic only shutter, but Sony decided to add higher flash sync speed and they kept the mechanical shutter to allow that.
