The new Sony Alpha A55, instead of being mirrorless, this new digital camera employs a "translucent mirror," more commonly known as a pellicle mirror. This advanced translucent mirror remains fixed in place during operation, allowing most of the light to reach the imaging sensor, while a small percentage is reflected to a dedicated autofocus sensor. It's what this high technology allows that's so exciting: real-time, phase-detect autofocus while firing off up to ten 16-megapixel images per second in the A55, and seven 14-megapixel frames per second in the A33. To get 10 frames per second from any other camera, you'd need to consider the top of the range of professional cameras ; and they're still not capable of real-time autofocus between shots like the new Sony Alpha SLT cameras. Real-time phase-detect autofocus is also constantly available in Movie mode, something no current SLR can achieve.
