Image on top: The Dynax 9 battery grip (here on eBay).
DynaxDigital forum user REX posted some A99 report, the A99 has:
Dual focus system-first
Battery grip like Dynax 9-The battery in the body of the camera stays in so you can have additional another two in the grip
1 pure SD and one SD/MS slot like a77
Perfect camera for video because a lot of accessories are for video made
The camera is incredible fast on autofocus….
Now SAR reader, you can guess what “Dual focus system” means
