Sony has brought out its first Alpha digital SLR, the a100, and sister site Computeractive has taken an early look at the camera.

While perhaps not ready to dethrone Nikon, Canon and Olympus, which dominate the entry level dSLR market - Sony's a100 is an impressive debut that comes with some neat touches.

It's 10megapixels for a start, but also has an eye sensor that automatically switches on the viewfinder and focuses when you raise your eye to it.

Plus it comes with in-camera (rather than in-lens) anti-shake technology, which is not that common in the dSLR market, and an anti-dust setting. This will shake free any dust that lands on your sensor when changes lenses - Olympus has this in its dSLRs, but its still a rare feature.
