- Wouldn't you want the same thing in a camera body? If you were to drop it
- wouldn't you want the delicate "inards" and fragile lens elements to be
- cushioned against the shock when it hit the ground. Yes, there is the
- chance that the case will split, but the camera will probably still
- function. With a metal camera you might put a dent in it that could
- jam up a critical part of the mechanism, or the shock of the drop might
- make things quit altogether. Note the use of "might" and "could". All
- I am saying is that there are two sides to this issue. "Plastic" is
- not always bad, nor is metal always good.
