Lens Step-Up Adapter Massa from 30mm to 37mm SB897

The Massa Lens Step-Up Adapter SB897 converts a 30 mm filter or accessory thread to a 37 mm thread, enabling attachment of larger 37 mm filters, caps and other accessories to lenses with a 30 mm thread. Constructed from metal, the adapter creates a reliable mechanical connection between lens and accessory while maintaining a compact profile. The adapter is compatible with lenses and accessories that share the stated thread diameters and is intended to help standardize filter sizes or use a wider range of accessories without replacing existing equipment.

Advantages

The metal construction provides a stable and durable connection while remaining lightweight. The step-up design allows photographers to use more commonly available 37 mm filters on lenses that originally accept 30 mm threads, reducing the need to purchase multiple filter sizes. The adapter preserves lens functionality and alignment by mounting externally on the lens thread, and its simple screw-on installation ensures repeatable, secure attachment of filters and caps.

Suitable for

• Attaching 37 mm filters (UV, polarizing, ND) to lenses with a 30 mm thread
• Using standard 37 mm caps and hoods on lenses with 30 mm threads
• Standardizing filter sizes across a set of lenses to reduce accessory inventory
• Macro, compact or specialty lenses that use nonstandard small threads

Key specifications

• Step-up from 30 mm (female) to 37 mm (male) thread
• Material: metal construction for mechanical stability
• Finish: matte/neutral finish to minimize reflections
• Weight: low-profile, lightweight design for minimal added bulk
• Mounting: screw-on installation to lens filter thread

How to use

Screw the female 30 mm side of the Massa SB897 adapter onto the lens' 30 mm filter thread until it is hand-tight and properly seated. Then attach the desired 37 mm filter, cap or accessory by screwing it onto the adapter's 37 mm thread. Ensure threads are clean and free of debris before installation to prevent cross-threading. For removal, unscrew the accessory first and then remove the adapter from the lens.

Usage recommendations

Use the adapter when you need to expand filter options or standardize accessory sizes; avoid overtightening to protect thread integrity. When working in dusty or humid environments, store the adapter and attached accessories in protective cases to prevent contamination and corrosion.
