## Summary description

Massa reduction/adapter ring for photographic use that converts a 39mm thread to a 42mm thread (39→42). Compact metal accessory designed to allow mounting of 42mm filters, lenses, or accessories onto 39mm-threaded optics. Useful for photographers needing compatibility between filter sizes and lens threads without replacing existing equipment.

## Long description

The Massa lens adapter ring from 39mm to 42mm, model SB3602, is a compact metal reduction/adapter designed to convert a 39mm male or female thread to a 42mm thread (39→42). It enables mounting of 42mm filters, step-up/step-down accessories or small lens attachments onto optics with a 39mm thread without modifying the original lens. The adapter preserves thread alignment and provides a simple mechanical interface for combining existing filters and accessories across these two common filter sizes.
Advantages
This metal adapter offers a lightweight and durable solution for matching 39mm lens threads to 42mm accessories. Its compact profile minimizes added bulk at the front of the lens while maintaining secure threaded connections. The adapter removes the need to purchase duplicate filters or swap multiple rings, improving workflow efficiency for photographers who use multiple lenses and want accessory compatibility between 39mm and 42mm items.
Suitable for
 Mounting 42mm screw-on filters on lenses with a 39mm thread
 Attaching small 42mm accessories such as close-up lenses or converters to 39mm optics
 Adapting existing 42mm filters or caps for use with older or compact lenses that have 39mm threads
Key specifications
 Material: metal construction for durability and thread stability
 Thread conversion: 39mm to 42mm (39→42)
 Finish: matte or plated metal surface to reduce reflections
 Form factor: low-profile ring that adds minimal extension to the lens front
 Compatibility: designed for standard 39mm and 42mm screw-type filter threads
How to use
Screw the Massa adapter gently onto the 39mm thread of the lens until it seats securely without forcing. Then screw the 42mm accessory or filter onto the outer 42mm thread of the adapter in the same manner. Ensure threads are clean and free of grit before assembly to avoid cross-threading. When removing, reverse the process by unscrewing the accessory and then the adapter. The adapter can remain on the lens if regular use of 42mm accessories is required.
Usage recommendations
The adapter is intended for mechanical thread conversion only and does not provide optical correction. Check for compatibility of filter thickness and accessory clearance to avoid vignetting on wide-angle lenses. Store the adapter in a small protective pouch when not in use to prevent scratches and keep threads clean.
