What are the problems associated with built-in electronic flashes?
This integrated flash system irons out the major problems photographers face with an external flash such as the flash guide number calculuation for the flash-to-subject distance, the film speed and the aperture setting. [ Also, remember the aperture problem with zoom lenses we pointed out on the topic on F-Stop and Aperture!The built-in flash is handy and useful but it too has its share of
limitations. First, it consumes your camera battery since it uses the same battery as the one that powers your camera. Second, it is a low power flashlight as camera designers have to compromise on flash power and battery life! This built-in flashlight has a working range of 12 feet or 4 meters. Zoom compact may have as little as 6 feet or 2 meters on the telephoto end!
Built-in flash is almost useless when you zoom your camera lens to full telephoto. This is one of the reasons why we prefer a 3 times zoom rather than a 10 times zoom camera. You can improve the flash working range by changing the ISO setting to a higher ISO on a digital camera or use a higher speed film like ISO400 instead of ISO100. Changing from ISO 100 to ISO 400 will double your built-in-flash's working range. ]
