The eyecup is made of soft and durable silicone, so it allows for more comfortable viewing through the camera's viewfinder. Meanwhile, it can prevent scratching and damage to eyeglasses. What's more, the dome-shaped eyecup effectively shields light that may enter the viewfinder and cause flare. It also can be mounted to the viewfinder easily and securely.
It replaces Fujifilm EC-XT L Eyepiece and compatible with camera as below:
Fujifilm X-T5, X-T4, X-T3, X-T2, X-T1, X-H1, X-H2, X-H2S, GFX 100, GFX 100S, GFX 50S and GFX 50S II Camera.
