Hoya 67.0 Instant Action Adapter Ring

The new magnetic Hoya Instant Action filter holder system allows you to mount standard screw filters magnetically on your lens. Save a lot of time switching filters with the Hoya Instant Action System, so you never miss that one moment again. Here's how it works: 1. Screw the Hoya Instant Action adapter ring onto your lens - this can remain permanently on the lens. 2. Screw the separately available Hoya Instant Action conversion ring onto your screw filter. 3. You can now attach the filter magnetically to the lens. Since the Hoya Instant Action System is used together with the filter, the entire frame becomes thicker. Please note that this may cause vignetting on APS-C wide-angle lenses with a focal length of less than 14mm and on full-frame wide-angle lenses with less than 20mm.

• Ring diameter 70mm
