The new Kodak EasyShare DX7590 looks essentially identical to its predecessor externally, but replaces the older model's 4.2 megapixel (4.0 megapixel effective) imager with a 5.36 megapixel (5.0 megapixel effective) CCD sensor that yields a maximum image size of 2576 x 1932 pixels. Amongst other changes, the AF system has been upgraded, and now offers a choice of multi-zone, center-weighted, and spot (left, center, right) modes, and the new electronic viewfinder now sports 70% more resolution, for a total of 311,000 pixels. The fastest shutter speed is now 1/1700 second, and an extra white balance setting (open shade) has been added.
