The FinePix S2995 has a mechanical camera shutter which is better than most digital cameras that were released around the same time as it. Most cameras of this age and spec have an electronic camera shutter. A mechanical shutter controls how much light reaches the image sensor. Using a mechanical shutter usually results in a higher image quality as more space is available on the image sensor to capture light rather then controlling an electronic shutter.
A mechanical camera shutter is in fact the best camera shutter type across all digital cameras that are a similar age to the FinePix S2995.
The worst camera shutter type amongst comparable types of camera is electronic.
