## Long description

The Massa SB900 lens adapter reduces a 25 mm thread to a 37 mm thread in a silver finish. It is designed to enable mounting 37 mm filters and accessories on lenses or devices that have a 25 mm female/male thread, providing a straightforward mechanical connection for photography and videography. The adapter maintains alignment between the accessory and the optical axis while preserving a compact profile and a neutral appearance.
Advantages
The Massa SB900 adapter offers a durable and lightweight connection that expands compatibility between accessories of different thread sizes. Its silver finish resists corrosion and blends with many camera setups. The adapter is simple to attach and remove without tools, allowing quick swaps between filters or other 37 mm threaded accessories. It provides a low-profile solution that minimizes added bulk and helps maintain balance on small lenses or devices.
Suitable for
 Attaching 37 mm screw-on filters to lenses or devices with a 25 mm thread
 Mounting 37 mm step-up or step-down accessories such as lens caps, hoods, or converters

Key specifications
 Function: thread size reduction from 25 mm to 37 mm
 Material: metal construction (silver finish)
 Finish: silver-coloured surface treatment
 Form factor: low-profile ring adapter for screw-on accessories
 Compatibility: fits devices with a 25 mm external or internal thread to accept 37 mm screw-on items
How to use
Screw the Massa SB900 adapter onto the device or lens with the matching 25 mm thread until it sits securely but without excessive force. Then, attach the 37 mm accessory by screwing it onto the adapter’s 37 mm thread in a clockwise direction until snug. To remove, reverse the process: unscrew the accessory first, then the adapter. Avoid cross-threading by aligning threads carefully before applying pressure.
Usage recommendations
Check thread orientation and fit before full tightening. If the adapter feels loose or does not seat properly, inspect both threads for damage or debris. Use finger torque for attachment; avoid tools that may deform the adapter. Store the adapter in a dry place to preserve the silver finish.
