Ultra-compact Digital Cameras
The ultra-compact camera is immensely popular right now, mainly because it is so small. It fits in your purse, it fits in your pocket; you can take it with you anywhere, and it's always ready to go. It's a nice handy point-and-shoot camera.
The downfall to the camera's small size is that the lens has also become much smaller to fit inside the camera body. The viewfinder enables us to view the image without using the camera's LCD screen. The smaller camera's viewfinder, if it has one, is not accurate. The LCD screen is handy but it also takes away from the camera's power source. Having an accurate viewfinder is quite helpful.
Another compromise to the camera's small size is the elimination of buttons and external features that allow us to access the camera's more basic functions. Removing the buttons keeps the camera nice and sleek but it means navigation now requires going through the camera's menu system, which will slow you down while you're shooting.
