What are the disadvantage of digital camera?

Answer 1

The early models seemed to use more electricity than General Motors and they ought to have been supplied with bandoleers for holding the spare AA cells. Typically 1.6 amps at six volts would be needed and AAs don't last long under that current drain. In actual fact "basic" budget quality cells could barely get the camera to boot Modern cameras seem to be less greedy on the current but beware of cameras with custom batteries that cannot be recharged in the field.

In Arctic weather film is probably more reliable if one has a clockwork camera. (the problem is that batteries do not like the cold)
