Massa lens step-up adapter 28mm to 37mm silver — Massa SB898

The Massa lens step-up adapter 28mm to 37mm silver is a metal adapter designed to permit the use of 37 mm filters, caps and accessories on lenses or devices with a 28 mm thread. The adapter provides a simple mechanical solution to adapt filter size without altering optical characteristics, allowing photographers and videographers to standardize accessories or fit larger filters when required.

Advantages

The silver metal construction offers durability and reliable thread engagement while maintaining a low profile on the front of the lens. The adapter preserves the original lens optics because it only changes the filter attachment size and does not introduce additional glass elements. Its precision threading reduces the risk of cross-threading and ensures secure attachment of 37 mm accessories to 28 mm threaded lenses.

Suitable for

• Photographers who need to fit 37 mm filters to lenses with a 28 mm thread
• Videographers unifying filter sizes across multiple compact lenses or accessories
• Users who want to use standard 37 mm caps, lens hoods or adapters on smaller-threaded optics

Key specifications

• Material: metal
• Finish: silver
• From thread: 28 mm (female side for lens)
• To thread: 37 mm (male side for filters/accessories)
• Type: step-up (increases filter thread size)
• Compatibility: designed for lenses and accessories with matching 28 mm and 37 mm metric threads

How to use

Screw the adapter onto the lens front by aligning the 28 mm female thread of the adapter with the lens’ 28 mm male thread and turning it clockwise until gently seated. Do not force the adapter if resistance is felt; back off and realign to avoid cross-threading. Once the adapter is mounted, attach 37 mm filters, caps or other accessories by screwing them onto the adapter’s 37 mm thread in the usual way. Remove accessories and adapter by turning counterclockwise.

Usage recommendations

Check that the adapter does not cause vignetting with wide-angle lenses at intended apertures. For best results, tighten by hand only and avoid over-tightening. Keep threads clean and free of grit to maintain smooth attachment and prevent damage.
