The cameras, technical data
We have enrolled three digital cameras against G800. The first is Fujifilm’s FinePix A500, an entry-level compact camera, which has been announced more than two years ago. The 5 megapixel camera represents those cameras, present in many households, that are mostly used for recording family events. The second one used, is a more advanced compact camera from Samsung (Digimax S600), which is although just as old as the one from Fujifilm, it still has more features and has manual settings. As for the third we have chosen an entry-level digital single lens reflex (DSLR) camera, which is although obviously not a concurrent of G800, but it’s good to have an example of what a top phone knows compared to a “real” camera. We have used a 18-55 mm kit lens with 3X zoom, which has a larger angle of view than the lens on the compact cameras, but it has a smaller focal distance in tele mode due to this.
Pentax K100D Super
Comprehending the major specs of the cameras will probably be no problem to anyone, knowing the information from the previous pages. Unfortunately we have no exact information about the image sensor in G800, the manufacturer guards the secret of it very well, as neither the manufacturer, nor the size are known. We suppose that it is a 1/4” CMOS sensor, although some sources say that the phone has a 1/2.5” one, made by the manufacturer.

* - unofficial data
G800 is somewhere in the middle between a completely entry-level and a somewhat better camera, based on its features. We can set exposure correction (+/- 2 exposure value), ISO sensitivity and white balance on it, but there are no such settings for shutter speed and aperture. There are lots of theme presets, which is very welcome: portrait, landscape, sport, interior, snow, sunrise, autumn colors, night mode, counterlight, fireworks, text. There are three different resolutions available (5, 3, 2, 1.3 megapixel and VGA), JPEG compression can be set in three steps. Autofocus can be turned off in the menu, which is something I don’t really understand, as we cannot set it manually.
There is 3X optical zoom, that can be further expanded with a 3X digital zoom, and let me skip answering: why? Light metering can also be altered by the user, and the list of functions also includes image sequences, panorama and self timer. Macro mode is set separately; the lower aspis is around five cm. At the flash we can set a pre-flash mode for red eye reduction, but unfortunately the flash itself has a very limited use, no matter the Xenon technology. The reason for this is that we cannot set charge level, and neither does the camera’s software set it, which results in the same power of flash at any distance, so we get a burnt, white picture when we’re close to the theme; I think the ideal distance is about 1-1.5 meters. To tell the truth the Xenon flash doesn’t even give light on a longer distance.
