Updated: 3 days ago
The OLJ Type 2 lens hood was developed specifically for the legendary Nikkor-N 5cm F1.1, combining classic craftsmanship with an innovative, patented design.
Precision-crafted from solid brass and finished in elegant black paint, the Type 2 weighs approximately 198.73 grams, compared with just 23.523 grams for the original plastic Nikon hood. Its substantial construction reflects our commitment to durability, quality, and the preservation of exceptional vintage photographic equipment.
Innovative Filter Compatibility
The Type 2 lens hood offers versatile filter options:
62mm filters can be accommodated when the hood is mounted in its reversed position.
67mm filters can be installed within the hood system, making it particularly suitable for variable ND filters.
Patented Reversible Design
Unlike conventional lens hoods, the OLJ Type 2 can be reversed and securely screwed into position, providing additional protection for the valuable Nikkor-N 5cm F1.1 lens during storage and transportation.
This innovative reversible design is protected by Japanese Patent No. 7650527, granted on January 17, 2025.
Designed and developed by Old Lens Junkies (OLJ), Japan, the Type 2 represents our dedication to preserving the character of historic lenses while introducing practical improvements for modern photographers.
