Filter adapter ring B&W 77mm to 67mm model 1102876 (77→67mm)

B&W filter adapter ring 77→67mm model 1102876 allows lenses with a 77 mm filter thread to accept 67 mm screw-in filters. This reduction ring provides a secure mechanical connection between a larger lens thread and smaller 67 mm filters, preserving proper alignment and enabling the use of UV, polarizing, neutral density and other standard 67 mm photographic filters without vignetting on compatible lenses.

Advantages

The adapter ring is machined to ensure concentric alignment and a reliable screw fit, reducing the risk of cross-threading when mounting smaller filters. Its slim profile minimises additional extension beyond the lens front, helping to prevent vignetting with wide-angle lenses when combined with appropriately thin filters. The metal construction offers durability for repeated attachment and removal during field use.

Suitable for

• Attaching 67 mm UV filters to lenses with 77 mm threads
• Using 67 mm circular polarizers on lenses that have larger threads
• Mounting 67 mm neutral density filters for exposure control
• Adapting small screw-in filters for travel or when using a single filter across multiple lenses

Key specifications

• Thread conversion: 77 mm female to 67 mm male
• Material: metal construction for strength and longevity
• Profile: low-profile design to minimise added extension
• Finish: matte or black coating to reduce reflections
• Compatible filter type: 67 mm screw-in photographic filters

How to use

Gently screw the adapter ring into the lens front thread (77 mm) until it seats securely without forcing; then screw the 67 mm filter into the adapter in the same way. Check alignment visually and confirm the filter turns smoothly while threaded. When using polarizers, mount the adapter and filter combination, then rotate the polarizer to adjust the effect. Remove by reversing the process, avoiding excessive torque to protect threads.

Usage recommendations

For best results, use slim-profile 67 mm filters on wide-angle lenses to minimise the chance of vignetting. Clean threads on both lens and filter before mounting to ensure smooth operation and to reduce wear. Store the adapter with a protective cap or inside a pouch when not in use to prevent dents or debris from affecting thread engagement.
