The size if the chip is sometimes given in the camera spec, but you can also guesstimate the size by the "focal length multiplier" and/or the focal length of the so-called normal lens. For example, if the normal lens is 14 mm, then you can guess that the CCD array has a diagonal of around 14 mm. That would be an equivalent to a focal-length-multiplier of 50/14= 3.6. rafe b. - Please: Stay on topic. Trim quoted messages. http://www.leben.com/lists for list instructions.
