The 4.3v and 4700 are not the number of megapixels. These cameras have, just like all of the others, somewhere around 2.7 real megapixels. Divided by four, of course, because each pixel has a filter over it. For each four pixels, there is one red, one blue, and two green pixels. So a 2 megapixel sensor really only has 500k full color pixels. This is also why some of the new (very expensive) cameras have three sensors and a light splitting prism (Foveon) and why most hi res backs for LF cameras (BetterLight) have a very hi res single line of pixels and scan the image three or four times. Subject can't move. Exposure time from high seconds to many minutes. They no longer use those high rez 24 squillion lp.mm lenses for making chips. It is all done via computer files and computer driven process equipment. Those lenses were super super sharp only at one wave length of light, somewhere in the green spectrum, so totally unusable for photography. Jim
