Ewa-Marine ZOOM-Extension Ring for Lens Port of 3D Underwater Housing
Key Features
  • Compatible with 3D Housings Only
  • Increase Zoom without Touching Glass
This ZOOM-Extension Ring from Ewa-Marine is inserted into the lens port from the inside of their 3D housings prior to installing your camera. It has no thread but simply sits in the port after easily sliding in. The extension allows you to zoom in more with your camera's lens without risking contact between the lens and the port's glass front element. It is recommended for use with longer focal lengths because it may cause vignetting at wide angles. It is compatible exclusively with 3D housings and is included with the 3D-L housing. The extension is made from Desmopan, a plastic material with a rubber-like feel.
