New Sony Digital SLRs With Two Image Sensors

Dslr-sony

Sony’s latest digital SLR models, the and the Alpha DSLR-A350, introduce an innovative, dual-sensor approach to previewing your image in real-time on the LCD screen, just as you can do today with digital point-and-shoot cameras.

Although Sony is not the first company to use two sensors to generate a live preview, the company is the first to offer both live preview and full control of the auto-focus system, including during rapid-fire burst-mode shooting.

Live view remains a relatively new feature on digital SLR models. By definition, with a digital Single Lens Reflex (SLR) camera, you see what the lens sees; but, the actual image is captured when you flip up the mirror and open the shutter. In order to offer a live preview of an SLR model, manufacturers have typically had to preview the image off of the same sensor that handles capturing the image.

The first digital SLR with a live LCD preview–Olympus’ $1000 (with 14-45mm lens) EVolt E-330–came out about a year ago. Now, several other manufacturers–including the $1300 (body only) Canon EOS 40D and the $4500 Canon EOS 1D Mark III, and the $1800 (body only) Nikon D300 and $5000 Nikon D3 and Nikon D3–are offering this feature; and the recently introduced Pentax K20D ($1300 body only) that does so as well. The Sony A300 costs $800 for the body only, or $900 for the body plus an 18-70mm lens.
