Sony has expanded its range of Alpha digital SLR cameras with two  affordable new entry-level cameras.

The DSLR-A390 and DSLR-A290 offer a dramatic step up in picture quality and creative options from point-and-shoot compact cameras, says Sony. They both have sensors with an 14.2 effective megapixels resolution and speedy shooting responses.  The Alpha 390 (below) adds Quick AF Live View, which teams the convenience of live image preview on the tilt-angle Clear Photo LCD with a speedy phase-detection autofocus.

Both cameras feature a new grip design that allows even more comfortable handling. Upper control areas of both models have also been revised with a clear, uncluttered new button layout.

For newcomers, the intuitive graphic display aims to make it easy to understand the relation between shutter speed and aperture, plus the effects of your chosen exposure settings on the final picture.

The Alpha 390 and Alpha 290 include a mini-HDMI terminal for direct connection to any HD Ready TV (using an optional cable).

Both models will be out this summer.
