Imaging Resource Reviews HP Photosmart R707
Imaging Resource have just reviewed the new HP Photosmart R707, a stylish 5 megapixel digital camera.
“High barrel distortion at wide angle. “Purple fringing” at wide angle, severe coma at telephoto. Geometric distortion on the R707 is a good bit higher than average at the wide-angle end, where I measured approximately 1.17 percent barrel distortion. The telephoto end fared a little better, as I measured approximately 0.2 percent barrel distortion. While chromatic aberration seems low, the wide angle images show a fair bit of what looks to be “purple fringing”, a bright purple fringe around dark objects against bright backgrounds. At telephoto focal lengths, severe coma blurs the corners of the image badly, extending a fair ways into the image area. Overall, its lens appears to be one of the weaker elements of the R707’s design.”
