This is the question most beginner photographers will have in their mind. If all you do is street photography or shooting portraits, you don’t actually need a remote. For those cases, the default shutter control is the right option. However, there are some situations where a remote is necessary. If you are shooting long exposures at night or trying to capture a picture of the milky way, even the slightest movement of the camera can ruin the picture. A remote will let you release the shutter without touching or shaking the camera. Another less common scenario is taking group selfies.
