Any bricks yet?
I don’t think I need any of the new features mentioned…but more stability would be nice. There are definitely times where my A1 kind of spaces out until I pull the battery.

"Allows simultaneous deletion and rating of images stored on both memory card slot 1 and slot 2"
hmm... wonder if this allows tagging photos to both cards along with tagging photos to the remaining card when one has been pulled? tagging = protected

Anybody else see the Firmware Update 4.0 notification/msg today appear on the rear screen when they power on their A1 camera?
I reported this notification message the last time we had a firmware update on the A1, but I don't think I heard anyone else mention it on this forum.

My single 3rd party battery still works with no message.
The update seems to reset some of my settings (I expected that though).
Didn't have time to take more than a handful of snapshots...

If the A1 had precapture it would be THAT camera for the Sony system, minus the new screen hinge mechanism. Alas...

I took a photo this time. Just to make sure I wasn't seeing things Ha!
This firmware update notification appears as soon as I turn on my camera. *I auto connect with bluetooth and the Creators' app on my iPhone as soon as I power on the camera which may have something with this msg that displays on my camera screen.

Don’t have my A1 anymore, but it looks liked a decent update
I’m guessing that’s about all they can add through software. Anything more would require newer hardware

"The update seems to reset some of my settings "
Did you use the new Creator's app backup settings to the Cloud feature before doing the 4.0 firmware update?

No "notification" message after turning on the camera but in settings/version the software update button is active (body must not be in custom 1-3 mode for it to be active).

I also noticed a little asterisk like symbol on the Setup icon on the camera's menu indicating a firmware update notification as well before I completed the update. I've not noticed this update symbol appearing on the Setup icon previously.
After updating the A1 to 4.0 via the Creators' app from my iPhone and as expected, both the rear screen firmware update msg and the little update symbol on the Setup icon in the camera menu are now gone ✅

Note**
For those that update or updated to v4.0 using the Creators' app, don't forget to delete the update file "BODYDATA.DAT" from the SD or CFexpress card after the update has completed to avoid any issues with future updates.

Not sure what this means "Improves the operational stability of the camera" but it comes with any firmware update
As to other benefits I only see spot XL and Xs are potentially good for use
The rest is just meh ....
Not sure if this warrants an update since I may have to reprogram everything

I'm looking into this new security feature for the A1 v4.0:
"No longer supports the Security (IPsec) functionality.
Please enable and use Access Authen. for enhanced protection and security...
Access Authen.:
Sets whether to encrypt communication with access authentication. ([On] / [Off])"
https://helpguide.sony.net/ilc/2420/v1/en/contents/221h_access_authentication_settings.html?search=Access%20Authentication
I suppose newer Sony cameras already have this "Access Authen" feature for some time. Anybody notice any differences or run into any operational issues with this feature on the other cameras?
Some interesting/important notes from the guide to pay attention to if "Access Authen" is turned off:

I *think* my camera turns on and is ready to shoot a bit faster.
🤔
Also, FYI, all of my custom buttons and such preserved their programming.

I'm positive my turns on and is ready much faster. Maybe mine had a slight issue with turn on and ready for work before, but not anymore. I used to think my Canon DSLRs were the fastest. I don't think so anymore. It seems to be a bit faster than my a9 III and maybe twice as fast as the a7r5 in my completely unscientific testing.
Also all custom buttons/functions retained using the update via cfe card.
