INON 45 degree Viewfinder

The 45° Viewfinder is an interchangeable finder unit to extend eye-point of camera's viewfinder without changing image size (x1.0) to see all finder image area even through a mask without vignetting. The eye piece is at 45 degree angle to camera's optical axis which helps to shoot lower subject like a goby on seabed.

This 45 degree viewfinder is of prism design using bright, high light transmission multicoated glass optics and offers full-sized 1:1 viewing. The viewfinder swivels 360 degrees for vertical or horizontal orientation. Constructed of lightweight corrosion-resistant aluminium. Waterproof to 100.

SPECS
The viewfinder swivels 360 degrees for vertical or horizontal orientation.
Constructed of lightweight corrosion-resistant aluminium. Waterproof to 100 m.
The 45 degree Viewfinder extends the eyepoint without changing the viewfinder image size (as when viewing the camera’s finder directly, i.e. by x1.0) so that 100% of the camera's finder image can be seen without vignetting even when viewing through housing/mask.
The eyepiece is positioned at a 45 degree angle relative to the camera's optical axis which helps in shooting situations like imaging a small subject on the seafloor, by enabling the diver to keep their body off the ground and head at a more natural position relative to the housing.
Also the eyepiece rotates 360 degrees to help when shooting vertical compositions, especially from low angles.
Anti-reflective multi-coated glass optics for high light transmission and bright, clear viewfinder image. Lens construction: 4 lens groups with 6 lens elements.
