DOF problem found with the Nikon Z6 and Z7 (Page 2): Having the shutter open when changing lenses isn't a problem IMO. If you closed the shutter and dust got on it while changing, it's...

Having the shutter open when changing lenses isn't a problem IMO.
If you closed the shutter and dust got on it while changing, it's still inside the camera.
Once the shutter cycles the dust can easily travel to the "dust magnet" you mentioned.

This opened a whole new train of thought for me. I understand a reason for the shutter being open when the camera is turned off. While the camera is being operated the shutter needs to be open for the EVF to work. With the shutter's default position being open, that means no power is being consumed to keep it open while in use. I don't know how the system operates when you squeeze the shutter, but that would be when some power is used and only then.
Sounds like a fine idea to me.

Wow. I would expect some dust as a normal thing, but enough to cause a problem, no. Are you using a zoom (aka bellows)?
If you're having that much of a problem I doubt a close shutter would solve the problem. When you change a lens dust will settle inside the cavity and tend to move around whenever the shutter actuates.
Do you live in Kansas or maybe the Texas pan handle? Mercy!
(yeah, I know ID. Rhetorical question)

Heh heh.

I read about the possibility before buying, but dissed it. In part because it isn’t an issue on my mirrorless Panasonic GM5.

I need to check if my Panasonic closes shutter.

Maybe I don’t notice it on Panasonic because I apply lower stops.

But stupid in practice.

I understand Sony’s close shutter on power off.

Which of course means their camera is burning power to hold the shutter open while in use.
A design decision, stupid? Maybe maybe not. What were the trade offs? That is one thing we will probably never know. I do know there haven't been a whole lot of complaints about dust to date that I've c seen at the various sites. At the same time there have been groans about battery usage at about the same frequency as the dust gripes. It would be a lot worse if the Z's had to hold the shutter open.

I have no issues with battery life. The complaints are based on nonsense standard. I get about a month on a battery, just like my D800 did.

I too have seen only a few complaints on dust. But for me it is a big issue.

(PS: I have seen many stupid design decisions as a nuclear system engineer. Most are because they missed something in the design criteria. Like the idiots at Boeing that killed 350 people. )
