The Mamiya Angle Viewfinder enables viewing, focusing and composition from a comfortable posture for low-angle, macro, copy work and other photography.
When mounted on the camera, the finder can be rotated 360 degrees perpendicular to the camera's viewfinder, allowing for photography at positions other than eye level
The view through the Angle Finder shows the same amount of information from the focusing screen as you would see without the finder mounted on the camera
It is attached by merely sliding it up into the camera's viewfinder and securing it with a locking lever
Diopter adjustment is possible in the Angle Finder with a range of -5 to +3, to accommodate near or farsighted vision
