Sony unveils 8-megapixel camera for pros

The consumer electronics maker announces a new digital camera with a filter that it says brings color fidelity closer to human visual perception.

Sony announced on Friday a new digital camera with a filter that it says brings color fidelity closer to human visual perception.

The new model in its Cyber-shot F-series of digital cameras incorporates Sony's recently developed four-color filter technology and real-imaging processor.

The new color filter in the DSC-F828 model adds an emerald-colored pixel to the filter pattern, in addition to the red, green and blue used in digital cameras. The camera's new imaging processor then converts the four-color signal back into three colors with a linear matrix system.

The model's 8-megapixel charge-coupled device (CCD) image sensor offers 3,360 pixels by 2,460 pixels, equivalent to 11-by-17-inch prints at 200 dots per inch or 8.5-by-11-inch prints at 300 dots per inch, the company said in statement.

The camera's processor is also designed to improve responsiveness, reducing shutter lag and cycle time, Sony said. With about a 40 percent cut in processing time, it can capture an 8-megapixel image in almost half the time that a 5-megapixel camera takes. The new camera also has manual controls, giving photographers a range of mechanisms to determine focus, exposure and recording modes.

Digital camera makers have been emphasizing style and ease-of-use over technology to gain market share at the entry level. But with its new launch, Sony is targeting experienced users and professional photographers.

The new model is expected to hit store shelves in mid-November and will cost $1,200.
