The H30B base mounts to HoodLoupe optical modules to give you the ability to fit up to 3" LCD screens. The HoodLoupe optical module is placed over the base with the latches snapped into the locking position. You can easily switch between mounting bases to accommodate the LCD screen size you will be viewing for the day. The base integrates with all Hoodman live view mounting plates.

*This base fits all Nikon LCDs (except models D5, D750, D500 & D5600 which requires the H32B base)
**Optical Module not included
