Reminder: Before installing the ULH-40B lens hood, you need to unscrew the plastic ring on the lens, and then install the lens hood.
The lens hood is a common photographic accessory set in front of the camera lens. It has the following uses:
1. The hood can make your lens look longer, cooler and more professional;
2. The lens hood can prevent the lens flare from sunlight or flash from entering the lens and making the photo whitish;
3. The hood can also protect your beloved lens to prevent it from being scratched or broken.
Due to the design problem of Olympus 45mm f1.8 lens, there will be a slight looseness after attaching the lens hood. The original factory is also the same, please know, please be careful if you mind.
