Using shutter priority mode is the best option when you are filming things in motion and you want to achieve a sharp, crystal clear image.

In these instances, you would turn the dial to have the fastest possible shutter speed.

Conversely, in some creative endeavors it is appealing to have a slightly blurred image to give the essence of speed or motion.

With that in mind, you can turn the shutter speed dial down to a slower speed in order to achieve this effect.

It’s important to be aware that there is a minimum shutter speed you should shoot at when taking hand held photographs.

There’s no hard and fast rule between shutter speed and lens size, but a good rule of thumb is that you should not shoot at a shutter speed that is lower than the side of the lens.

For instance, if you have a 50mm f1.8 on, you shouldn’t drop the shutter speed below 1/60s as the resulting image will likely be blurry.

If you’ve got an 80mm f1.8 on, then you shouldn’t drop the shutter speed below 1/125s.

Using this kind of rule in low light conditions with you lenses will help you to get the sharp images you’re after.
