Inon 180° Straight Viewfinder for Inon & Isotta Underwater Housings

 The Straight Viewfinder is an interchangeable finder unit to extend eyepoint of camera's viewfinder without changing image size (x1.0) to see all finder image area even through a mask without vignetting. The eyepiece is level to camera's optical axis to position camera/housing closer to a subject without changing your position.
