Massa step-up adapter ring 67mm to 77mm SB1828

The Massa step-up adapter ring 67mm to 77mm SB1828 allows lenses with a 67mm front thread to accept 77mm filters, hoods and other accessories. This mechanical adapter provides a lightweight solution for mounting larger-diameter filters or converters on lenses with smaller filter threads, enabling photographers to share 77mm accessories across multiple lenses without changing the lens itself.

Advantages

The adapter is constructed to maintain a low profile and minimal added weight while providing a secure threaded connection between 67mm lens threads and 77mm accessories. By using a step-up ring you avoid vignetting that can occur when stacking incompatible filter sizes and reduce the need to buy duplicate filters. Its simple screw-on design makes it easy to attach and remove in the field.

Suitable for

• Attaching 77mm screw-on filters (ND, polarizer, UV) to lenses with 67mm threads
• Mounting 77mm lens hoods or converters on 67mm lenses
• Sharing larger filters among camera bodies and lenses during shoots or travel

Key specifications

• Thread conversion: 67mm (male) to 77mm (female)
• Type: step-up adapter ring (mechanical screw-on)
• Material: lightweight metal alloy (corrosion-resistant finish)
• Profile: low-profile design to minimize added length

How to use

Screw the adapter onto the lens front by matching the adapter's 67mm male thread to the lens' 67mm female thread and turn clockwise until finger-tight. Then screw the 77mm filter or accessory onto the adapter's 77mm female thread until secure. Remove accessories by reversing the process. Ensure the threads are clean and free of grit before mounting to prevent cross-threading and damage.

Usage recommendations

For best results, check for vignetting with wide-angle lenses after attaching large filters; remove any stacked filters that cause darkening in the corners. Store the adapter in a padded pouch when not in use to protect threads and maintain smooth operation.
