## Summary description

Step-down filter adapter B&W 1102871 reduces a 67mm lens filter thread to 49mm. Designed to allow use of 49mm filters or accessories on lenses with a 67mm thread, it preserves mechanical alignment and secure attachment. Suitable for photographers needing to adapt existing 49mm filters to larger lenses for shooting, travel, or kit consolidation.

## Long description

The B&W step-down adapter 67mm to 49mm model 1102871 is a mechanical thread reducer that lets photographers attach 49mm filters and accessories to lenses with a 67mm filter thread. It maintains the correct alignment of the filter plane and provides a secure, threaded connection without adding significant bulk to the optical system. The adapter supports use of existing 49mm glass or plastic filters on larger lenses, enabling convenient consolidation of filter kits and flexibility when changing lenses during shoots or travel.
Advantages
The adapter delivers a precise thread fit between a 67mm lens and 49mm accessories, preventing wobble and ensuring stable mounting during handheld or tripod work. Its slim profile minimizes vignetting on wide-angle lenses while keeping the optical distance close to the original lens design. The metal construction provides reliable mechanical strength and consistent performance over repeated attachment cycles. The simple, screw-on operation makes attachment and removal quick and tool-free.
Suitable for
Photographers who own 49mm filters and need to use them on lenses with a 67mm thread
Travel and field work where reducing kit weight and number of items is beneficial
Portrait, street, and landscape shooting where filter changes are required on multiple lenses
Key specifications
Thread conversion: from 67mm (lens side) to 49mm (filter side)
Construction: slim, low-profile design to limit vignetting
Material: metal alloy for durability and stable threading
Attachment: screw-on threaded connection for secure mounting
Weight: lightweight to avoid substantially altering lens balance
How to use
Screw the adapter onto the front filter thread of the lens by aligning the threads and turning clockwise until hand-tight. Then attach the 49mm filter or accessory to the adapter by screwing it on in the same manner. To remove, unscrew the filter first and then the adapter, taking care not to apply sideways force that could stress the lens threads. Regularly check for tightness during extended shoots to prevent accidental loosening.
Usage recommendations
Use the adapter primarily when you need to reuse 49mm filters on lenses with a 67mm thread; avoid stacking multiple adapters or thick filter stacks on wide-angle lenses to reduce the risk of vignetting. Store the adapter in a protective pouch when not in use to preserve thread integrity and keep both lens and filter threads clean.
