The Inon 45-degree viewfinder is a perfect solution for critical focus and tired eyes.
The 45° Viewfinder is an interchangeable finder unit to extend the eye-point of the camera's viewfinder without changing the image size (x1.0) to see all finder image areas even through a mask without vignetting. The eyepiece is at a 45-degree angle to the camera's optical axis which helps to shoot lower subjects like a goby on the seabed. Also, the eyepiece is rotatable 360 degrees making it easy to shoot vertical composition from a low angle.
