Have you ever wondered what's meant by "effective" megapixels? So have I. In the case of Fujifilm's FinePix S5 Pro, the CCD image sensor uses technology that splits the pixels into two groups: S-pixels and R-pixels. S-pixels are concerned with main image information, while R-pixels primarily store detail in the highlights (Fujifilm also used this "SR double pixel technology" in the FinePix S3 Pro). The S5 Pro has 6.17 S-megapixels and 6.17 R-megapixels, which gives us 12.34 megapixels "effectively." The result, theoretically anyway, is better color and reduced noise. Other "super" features include a Nikon F-mount for compatibility with most Nikkor lenses and the ominously named "face detection technology." Now your mom can press a button, detect up to 10 faces in an image and zoom in on your mug to make sure your tongue stayed in your mouth. We expect this camera to drop in February 2007; no price yet. — Elliot Black
