Will A77 and A99 support UHS-2 Sd cards?

seeing that i got quite noticably better performance from the 95Mb/s UHS-1 card in my A77 i was wondering if the newly announced UHS-2 cards with 200+Mb/s will be useable and beneficial in the A77 or A99

 

please no comments on who needs to shoot 12fps for more than a sec Smiley Wink

We cannot guarantee if A77 and A99 can utilize the max speed of a UHS-2 card because we haven't tested it yet. Please check this link for SD Memory Card Compatibility Information for Sony alpha Cameras http://esupport.sony.com/info/589/US/EN/

Re: Will A77 and A99 support UHS-2 Sd cards?

okay, i did a little research and can answer this myself now:

-UHS2 cards will work but give no benefit over UHS1 as the A77/A99 dont have the additional connector pins for highspeed UHS2 so UHS2 becomes UHS1 in these devices..  in short: no speed gain from UHS2 Smiley Sad
