Lens Adapter JJC for Canon — 67mm Filter Thread (model SB4523)

The JJC lens adapter for Canon — 67mm filter thread (model SB4523) is an accessory that provides a standardized 67mm screw-in interface for compatible Canon lenses and adapters. Designed to accept 67mm filters such as UV, CPL and ND, this adapter allows photographers to mount commonly used screw-in filters on lenses that do not have a native 67mm thread. The adapter is intended to simplify filter attachment and expand compatibility across lenses used for landscape, portrait and travel photography.

Advantages

This adapter allows the use of widely available 67mm filters on Canon lenses without a matching thread, reducing the need to buy multiple filter sizes. It keeps filter mounting straightforward and secure with a standard screw-in connection. The adapter supports common filter types (UV, CPL, ND) used to control reflections, light intensity and color, enabling consistent results across different shooting situations.

Suitable for

• Landscape photography where ND or CPL filters are used to control reflections and exposure
• Portrait photography requiring UV protection or subtle polarization
• Travel and street photography when quick attachment of a neutral density filter is needed
• Photographers who own multiple lenses with varying filter sizes and want to standardize on 67mm filters

Key specifications

• Filter thread size: 67mm screw-in connection for standard round filters
• Compatibility: Designed for use with Canon camera lenses and compatible lens adapters that can accept an external thread adapter
• Supported filter types: UV, CPL, ND and other 67mm screw-in filters
• Material: durable metal and/or precision-machined components for secure mounting (manufacturer-specified materials)
• Mount style: external screw-in adapter that provides a male 67mm thread

How to use

Align the adapter with the front of the compatible Canon lens or existing adapter and gently screw it in until it seats securely, taking care not to cross-thread. Once mounted, attach a 67mm screw-in filter by rotating it clockwise until snug. To remove, unscrew the filter first and then the adapter from the lens. Ensure the contact surfaces are clean before installation to maintain a firm fit and avoid damage to threads.

Usage recommendations

Inspect threads on both the lens and filter for dirt or damage before mounting. Use only filters that match the 67mm thread size. Avoid over-tightening to prevent thread wear; hand-tighten until firm. When carrying the camera with a filter attached, support the filter to reduce stress on the adapter threads.
