## Summary description

Massa step-up adapter reducing or adapting a 40.5mm lens thread to accept 49mm filters and accessories. Model SB3329 provides mechanical connection between lenses and larger-diameter filters, enabling use of 49mm screw-on filters, caps or converters on lenses with 40.5mm threads. Useful for photographers who want to standardize filter sizes or reuse existing 49mm accessories.

## Long description

The Massa 40.5mm to 49mm step-up adapter (model SB3329) lets you attach 49mm screw-on filters and accessories to lenses with a 40.5mm front thread. This mechanical adapter preserves the lens thread while expanding the attachment diameter, so existing 49mm filters, caps or converters can be reused on smaller lenses without modifying the lens or filter.
Advantages
The adapter is lightweight and low-profile, providing a stable screw connection between a 40.5mm lens thread and 49mm accessories. It reduces the need to buy duplicate filters by enabling compatibility across different lenses. Its straightforward metal construction ensures consistent alignment and easy mounting and removal of filters or caps.
Suitable for
Attaching 49mm screw-on filters (UV, ND, polarizers) to lenses with 40.5mm threads
Using 49mm lens caps or protective covers on smaller lenses
Connecting 49mm adapters or converters to 40.5mm lenses
Standardizing filter sizes across a mixed lens kit
Key specifications
Input thread diameter: 40.5mm (lens side)
Output thread diameter: 49mm (filter/accessory side)
Material: metal alloy construction for dimensional stability
Finish: black matte coating to reduce stray reflections
Type: step-up (thread enlarger) adapter
Mounting: screw-in on both lens and accessory threads
How to use
Screw the adapter onto the lens front thread until it seats firmly but do not overtighten. After the adapter is in place, screw the 49mm filter or accessory onto the adapter’s outer thread until secure. To remove, reverse the process: unscrew the filter first, then unthread the adapter from the lens. Check thread alignment before tightening to avoid cross-threading.
Usage recommendations
For best results, use the adapter with slim-profile filters to minimize the risk of vignetting on wide-angle lenses. Regularly inspect threads for dust and grit and clean with a soft brush or cloth to maintain smooth operation.
