Filter holder adapter ring Hoya Instant Action Adapter Ring

The Hoya Instant Action Adapter Ring is a magnetic filter adapter ring for screw-type filters, designed to fit lenses with a 58 mm thread. It provides a quick way to mount compatible filters by combining the adapter ring on the lens with a separate Hoya Instant Action Conversion Ring on the filter. The adapter is finished in black and supplied as a single unit.

Advantages

The adapter enables one-move attachment and removal of screw-type filters using magnetic coupling, reducing the time needed to change filters and helping you avoid missing decisive moments. It also lowers the risk of dropping filters during mounting or dismounting.

Suitable for

• Photographers who use 58 mm screw-type filters
• Street, travel and event photography where fast filter changes are required
• Situations that demand quick switching between clear and filtered lenses

Key specifications

• Thread size: 58 mm
• Color: Black
• Package contents: 1 adapter ring
• Compatibility: Works with Hoya Instant Action Conversion Ring (sold separately) and compatible 58 mm screw filters

How to use

Screw the Hoya Instant Action Adapter Ring onto the lens thread (58 mm). Attach the Hoya Instant Action Conversion Ring to the screw-type filter you plan to use (conversion ring sold separately). Align the filter with the adapter and let the magnetic coupling secure the filter in place. To remove, pull the filter away from the lens; the magnetic connection will release cleanly.

Usage recommendations

Use with filters and conversion rings of the correct 58 mm size. Ensure both the adapter ring and conversion ring are clean and free of grit before attaching to avoid scratches on the filter or lens. Store separately when not in use to protect the magnet surfaces.
