Sony A55V and A33
Sony today introduced two new α cameras (models SLT-A55V and SLT-A33) that adopt Sony’s newly-developed Translucent Mirror Technology, which achieves the highest-level of auto focus speed for both still image and movie shooting. Translucent Mirror Technology provides performance previously unattainable with traditional DSLR technology. Using the new technology, theα55 andα33 models can continuously and quickly focus (with TTL phase-detection) while shooting stills and recording video—even in full HD, allowing desired moments to be captured in tack sharp focus, high-definition video.
