Sony has introduced NEX-5 and NEX-3 cameras with DSLR-quality imaging and the convenience of interchangeable lenses in a sleek new design that slips easily into a jacket pocket or bag. In contrast with conventional DSLR models, the ‘mirrorless’ construction shrinks the thickness of both cameras to just 24.2mm (NEX-5) at their slimmest point. As a luxurious extra refinement, the NEX-5 features a tough yet light-weight magnesium body, making it the world’s smallest and lightest interchangeable lens digital camera.

The new cameras use newly-developed Exmor APS HD CMOS sensor with a resolution of 14.2 effective megapixels. Far larger than the sensor inside conventional compact cameras, its key to the extremely low image noise and creative defocus effects that are familiar to DSLR users. Still and video image quality is further refined by the powerful BIONZ processor that ensures speedy DSLR-style shooting reflexes with quick, precise autofocus and minimal shutter lag. Both cameras can also capture fast-moving action with a high-speed burst of full-resolution images at up to 7fps (AF/AE fixed from first frame).

The camera features 3-inch Xtra Fine LCD with TruBlack technology that tilts up or down for comfortable viewing in any shooting position. The screen features an auto-brightness function for excellent visibility, even when you’re outdoors. The main difference between the two cameras is video recording. NEX-3 shoots HD video with stereo sound as compact MPEG4 files that are ideal for PC storage and web sharing. Full HD (1920 x 1080i) video captured by the NEX-5 as high-quality AVCHD files can be enjoyed on a connected HD television.

Sony NEX-5 with 16mm F2.8 pancake lens is priced $649 and with 18-55mm zoom lens is priced $699. The NEX-3 is priced $549 with 16mm lens and $599 with 18-55mm zoom lens. Both the cameras will ship this summer. DP Review has posted in-depth preview of NEX-5 and NEX-3 comparing the new cameras with other cameras in the category. Also CNET has added a hands-on video, which we have added below.
