Sony A55 and A33 cameras: Translucent mirror tech to "redefine" DSLRs

Cameras, Features, Tech Digest news

Sony have today launched two brand new additions to their Alpha range of DSLR cameras that use a new technology known as Translucent Mirror tech.

Translucent Mirror technology allows the new A55 and A33 interchangeable lens cameras to offer auto-focus at all times in Live view, allowing also for 1080i AVCHD video recording with continuous, reliable auto-focus.

It achieves this by replacing the traditional mirror and shutter set-up of conventional DSLRs with a translucent mirror that “splits” the optical path between the main sensor and an additional phase-detection autofocus sensor. According to Sony it will “redefine” shooting with a DSLR and opens up “dramatic” improvements to usability.

All this fancy new tech doesn’t mean that the portability of the cameras have to suffer either. Both the 16.2 MP A55 and 14.2 MP A33 models are small enough to give Micro Four Thirds models a run for their money.

10 frames per second shooting will be possible with the A55 and 7 fps with the A33 in continuous priority AE mode, giving it the lofty title of being the fastest burst continuous AF shooting mode in any interchangeable lens camera with an APS-C size sensor.

Other neat features include Quick AS Live View, 3D Sweep Panorama modes, anti-shake, an ISO range of 25600 and support for both SD and Memory Stick Duo cards.

Due out in September, no pricing has been revealed yet. Check out a few more images below whilst you wait for word to trickle in.
