The camera definitely tracks beyond f/11. Naturally it doesn't track as well as larger apertures but the on-screen displays shows the AF is tracking and the photo results support that as well.
Awesome, thanks for reporting this.
No Play Menories app support. Ever! It's missing from the menu and I confirmed with a Sony rep that there's no plans in the future for the camera to support apps. I asked if this means future models will drop support as well and was told no - this is specific to the A9. No explanation given why.
I'm not surprised by this, actually. I would assume that this is based on feedback from Pro's that probably regard Play Menories as kid tools, because they haven't tried any of them. Not all are as adventurous as Fred and others here , so that is a shame.
The electronic shutter does appear noisier than the mechanical but the differnece seems small. I took a test shot at ISO 25,600 and compared to the mechanical at 100% magnification on the LCD. I took snaps of both screens with my iPhone - you can download them here
There is a ton of electronic stuff happening on the sensor now, so this isn't surprising, especially for a first generation stacked full-frame sensor. It doesn't look too bad though and I would reserve judgment until we get raws to play with anyway.
Again, thanks for your report.
