## Summary description

Step-down filter adapter B&W 49mm to 46mm (model 1102852) allows mounting 46mm filters on lenses with a 49mm filter thread. Metal construction ensures secure fit and alignment; useful for photographers who need to use smaller-diameter filters across lenses with larger threads. Enables consistent use of filters such as polarizers or ND filters without buying duplicates.

## Long description

The Filter Step-Down Adapter B&W 49mm to 46mm model 1102852 enables the use of 46mm screw-in filters on lenses that have a 49mm filter thread. Constructed from metal, the adapter provides a precise and secure connection between the lens and a smaller-diameter filter, allowing photographers to reuse compact filters such as polarizers or neutral density elements across multiple lenses without adding bulk or purchasing extra filters.
Advantages
The metal construction ensures a stable fit and accurate alignment of the filter plane relative to the lens, reducing the risk of slippage or light leaks. By allowing smaller filters to be mounted on larger lens threads, the adapter saves cost and storage space while maintaining optical compatibility for common filter types. Its low-profile design minimizes vignetting on lenses where the filter stack remains compact.
Suitable for
Photographers who own 49mm-thread lenses and 46mm screw-in filters
Use with circular polarizers, neutral density filters and clear protective filters
Travel and field photography where reducing carried accessories is important
Mixing filter sizes across lens kits to achieve consistent effects
Key specifications
Step-down adapter size: from 49mm (lens thread) to 46mm (filter thread)
Material: metal construction for durability and precise threading
Thread standard: female-to-male screw threads compatible with standard photographic filter threads
Finish: machined surface to ensure smooth engagement and alignment
Profile: low-profile design to reduce risk of vignetting with moderate wide-angle use
How to use
Screw the adapter onto the lens filter thread with the larger (49mm) side engaging the lens. Ensure the adapter is seated and threaded evenly without cross-threading. Then screw the 46mm filter into the adapter until snug; do not overtighten. Check for any rotation needed for orientation-sensitive filters such as graduated or polarizing types and make final adjustments after the filter is mounted.
Usage recommendations
Inspect threads on both lens and filter before mounting to prevent damage; keep the adapter clean and free of grit. When using wide-angle lenses, verify that the adapter plus filter do not introduce vignetting at the desired focal length. For stacked filter setups, be aware that additional elements may increase the risk of vignetting and mechanical stress on the threads.
