■The role of eye mask■
The eyecup is mainly used to prevent light from entering the eyecup during long-term B-bulb exposure, and is an essential small part for taking pictures; it can also prevent the eyecup from scratching when the camera is not used; and prevent debris from entering the viewfinder when the camera is stored.
■How to use the eye mask ■
Remove the rubber eyecup before use, and then insert the eyecup into the card slot outside the viewfinder.![](https://img.alicdn.com/imgextra/i3/1047775531/TB29d_2k.UIL1JjSZFrXXb3xFXa_!!1047775531.jpg)
