Translucent Mirror Technology™
Other DSLRs can shoot. Or they can focus with the speed and precision of Phase Detection AF. They cannot do both at once. The SLT-A33 is the world’s first DSLR with Translucent Mirror Technology™ that directs light to both the image sensor and the Phase Detection AF sensor simultaneously. 

• 7 frames per second continuous
  The translucent mirror makes it far easier to capture the decisive soccer kick or your baby at her absolute cutest. The Sony® SLT-A33 camera shoots full, 14.2 MP resolution pictures at up to 7 fps while maintaining continuous auto focus and auto exposure. 
  
• Quick AF for Full HD Movie Capture
  When most DSLRs shoot video, their Contrast AF is slow and visibly “hunts” for focus. The Quick AF Full HD Movie retains the same fast, precise Phase Detection you enjoy for still images. It’s a decisive advantage for tracking fast-moving subjects and a major benefit of Translucent Mirror Technology™. 
  
• 14.2 megapixel resolution
  You get incredible detail and gorgeous enlargements. Thanks to the 14.2 megapixel APS-C sensor size and Sony® Exmor™ APS HD CMOS technology, the camera achieves high resolution with no penalty in low-light sensitivity or sensor noise. 
  
• APS-C size HD CMOS image sensor
  With 19.5 times the area of the typical camcorder image sensor, APS-C makes the difference between amateur and professional-looking video, delivering an exceptional combination of high resolution, high sensitivity and gorgeous, blurred backgrounds. 
  
• Sony® Exmor™ technology
  Conventional image sensors use only a handful of analog-to-digital (A/D) converters, which can slow you down. The Exmor™ sensor provides more than 4,000 column-parallel A/D converters. This helps enable continuous shooting at up to 7 frames per second. 
  
• Full HD 1080/60i movies
  This is one of the very few DSLRs with 1080/60i Full HD, exactly the same resolution and frame rate as most broadcast and cable HDTV channels. Records in 1080/60i AVCHD™ format, 1080/30p high definition in PC-friendly MP4 format and standard definition 480/30p in MP4 format.
  
• Multi-frame NR
  Experience incredible low-light shooting without a flash. The camera captures six images in a fraction of a second. Combining the data from all six, it creates a single image with a reduction in noise equivalent to two additional steps of ISO sensitivity. Sensitivity selectable up to ISO 25600. (Recommended for still subjects.)
