Step-down filter adapter B&W 67→58 mm 1102869 (67mm to 58mm)

Step-down filter adapter B&W 67→58 mm 1102869 is a precision reduction ring that allows attaching 58 mm filters to lenses with a 67 mm front thread. Machined from metal for stable mounting, this adapter sits between the lens and the filter and provides a reliable, compact solution when you need to use smaller-diameter filters on a larger lens thread. The adapter preserves optical alignment and keeps the filter securely in place while minimizing added bulk.

Advantages

The B&W reduction ring provides a snug fit and accurate thread engagement, reducing the risk of cross-threading or loosening during use. Its metal construction ensures durability and consistent performance under normal shooting conditions. By converting a 67 mm thread to 58 mm, the adapter enables flexible use of existing filter inventories without requiring additional larger filters, helping to reduce cost and carry weight for photographers who own multiple lenses.

Suitable for

• Attaching 58 mm screw-in filters (UV, polarizer, ND) to lenses with 67 mm threads
• Using a single filter across different lenses to minimize gear needed
• Situations where a compact, lightweight filter solution is preferred

Key specifications

• Input thread diameter: 67 mm (lens side)
• Output thread diameter: 58 mm (filter side)
• Material: machined metal construction for secure mounting
• Form factor: slim reduction ring designed to minimize vignetting on compatible lenses

How to use

Screw the adapter onto the lens front thread (67 mm) until it seats securely without cross-threading. Then screw the 58 mm filter onto the adapter until it is hand-tight. Check for any signs of vignetting at wide focal lengths and adjust mounting order if you use additional accessories, such as hoods or step-up rings. Remove filters and adapter by reversing the process and store them in protective cases when not in use.

Usage recommendations

Use the adapter primarily with filters that are thin or low-profile to reduce the chance of vignetting on wide-angle lenses. Avoid overtightening threads; hand-tighten to secure. Clean threads regularly and inspect for damage to maintain smooth attachment and prevent cross-threading.
