When Todd walked up to it an looked into the viewfinder he said a few words that were not fit for video. But, he regained his composure and did the interview.
The A65 and A77 cameras use a translucent mirror which means that the mirror does not have to move out of the way to make a shot. The A65 will shoot 10 frames per second (double what normal mirror viewfinder cameras can do) and the A77 can shoot 12 frames per second. Also, when shooting video, the mirror stays in place so the viewfinder works unlike most other DSLR type cameras.
