Lens Adapter Massa 27mm to 37mm Silver SB1104 — step-up ring

The Massa 27mm to 37mm Silver SB1104 step-up ring adapts a 27 mm threaded lens or device to accept 37 mm accessories. Finished in silver, this slim mechanical adapter provides a secure threaded connection for attaching 37 mm filters, caps or converters to equipment with a 27 mm thread. The adapter maintains alignment between lens and accessory while adding minimal extension, preserving optical characteristics and allowing use of a wider range of accessories without changing lenses.

Advantages

The step-up ring offers a lightweight, durable metal construction with a precision thread fit to reduce wobble and ensure stable attachment. Its silver finish blends with silver or neutral-colored lens barrels and minimizes reflections. The simple, tool-free design makes it quick to mount and remove while providing a reliable mechanical interface for photographic accessories.

Suitable for

• Attaching 37 mm screw-on filters to lenses or devices with a 27 mm thread
• Using 37 mm lens caps or protective covers on 27 mm equipment
• Mounting small 37 mm converters or step rings in compact photography setups
• Adapting accessories for compact cameras, action cameras, or small optics with 27 mm thread

Key specifications

• Material: metal construction for durability
• Finish: silver exterior coating
• Thread conversion: female 27 mm to male 37 mm
• Compatibility: designed for devices and lenses with 27 mm external thread
• Profile: low-profile, slim design to minimize added length

How to use

Screw the female side of the step-up ring onto the 27 mm thread of your lens or device until it is finger-tight and aligned. Then screw the 37 mm accessory, such as a filter or cap, onto the exposed male 37 mm thread until secure. To avoid cross-threading, start threads carefully and tighten by hand only; if necessary, back off and realign before re-screwing. Remove by reversing the process and store the adapter with protective caps when not in use to prevent damage to the threads.

Usage recommendations

For reliable results, use the Massa step-up ring with accessories that match the 37 mm thread standard and avoid overtightening. If using filters with polarizers or heavy glass, consider supporting the filter during adjustment to reduce stress on the lens mount. Clean threads periodically to remove dust and grit and keep the adapter in a dry place to maintain the finish and thread integrity.
